07 ThunderRoad

Your 06 should be the same as my 07 5.9 our trucks wiring and modual comm buss are different from all other 5.9 trucks and different, to a lesser amount, from the the 6.7 What colors are the wire and the plug that are drawing amps from the tipm? I will look it up in my service manual. Is the truck an ST OR SLT OR LARAMIE?

gunnie

the wire is grey / red stripe, I think I have eliminated everything except the sentry key and cluster connections, just don't know how to disconnect them.
thanks

07 ThunderRoad

I do need to know what optoin level the truck is. It makes a differance in some of the wiring.

INSTRUMENT CLUSTER
WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the supplemental restraint system before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the proper precautions could result in accidental airbag deployment.

If all of the instrument cluster gauges and indicators are ineffective, be certain to check the instrument cluster fused B(+) fuse and the instrument cluster fused B(+) and ground circuits for shorts or opens. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

If an individual hard wired gauge or indicator is ineffective, refer to the diagnosis and testing service information for that specific gauge or indicator. If an individual Controller Area Network (CAN) data bus message-controlled gauge or indicator is ineffective, perform the Actuator Test as follows:

CAUTION: Instrument clusters used in this vehicle automatically configure themselves for compatibility with the features and optional equipment in the vehicle in which they are initially installed. The instrument cluster is programmed to do this by embedding the Vehicle Identification Number (VIN) and other information critical to proper cluster operation into electronic memory. This embedded information is learned through electronic messages received from other electronic modules in the vehicle over the Controller Area Network (CAN) data bus, and through certain hard wired inputs received when the cluster is connected to the vehicle electrically. Once configured, the instrument cluster memory may be irreparably damaged and certain irreversible configuration errors may occur if the cluster is connected electrically to another vehicle; or, if an electronic module from another vehicle is connected that provides data to the instrument cluster (including odometer values) that conflicts with that which was previously learned and stored. Therefore, the practice of exchanging (swapping) instrument clusters and other electronic modules in this vehicle with those removed from another vehicle must always be avoided. Failure to observe this caution may result in instrument cluster damage, which is not reimbursable under the terms of the product warranty. Service replacement instrument clusters are provided with the correct VIN, and the certified odometer and engine hours values embedded into cluster memory, but will otherwise be automatically configured for compatibility with the features and optional equipment in the vehicle in which they are initially installed.

NOTE: Certain indicators in this instrument cluster are automatically configured. This feature allows those indicators to be activated or deactivated for compatibility with certain optional equipment. If the problem being diagnosed involves improper illumination of the cruise indicator, the electronic throttle control indicator, the fog lamp indicator, any of the four-wheel drive indicators, the overdrive OFF indicator, the tow/haul indicator, the transmission overtemp indicator, the security indicator or the gear selector indicator, disconnect and isolate the battery negative cable. After about five minutes, reconnect the battery negative cable and turn the ignition switch to the ON position. The instrument cluster should automatically relearn the equipment in the vehicle and properly configure the configurable indicators accordingly.



ACTUATOR TEST
The instrument cluster actuator test will put the instrument cluster into its self-diagnostic mode. In this mode the instrument cluster can perform a self-diagnostic test that will confirm that the instrument cluster circuitry, the gauges, and the indicators are capable of operating as designed. During the actuator test the instrument cluster circuitry will position each of the gauge needles at various calibration points, illuminate all of the segments in the Vacuum Fluorescent Display (VFD) unit, and turn all of the indicators ON and OFF again.

Successful completion of the actuator test will confirm that the instrument cluster is operational. However, there may still be a problem with the CAN data bus, the Powertrain Control Module (PCM), the Engine Control Module (ECM), the Totally Integrated Power Module (TIPM), the Transmission Control Module (TCM), the Occupant Restraint Controller (ORC), the Controller Anti-lock Brake (CAB), the Sentry Key REmote Entry Module (SKREEM) (also known as the Wireless Control Module/WCM) or the hard wired inputs to one of these electronic control modules. Use a diagnostic scan tool to diagnose these components. Refer to the appropriate diagnostic information.


1. Begin the test with the ignition switch in the OFF position.
2. Depress the odometer/trip odometer switch button.
3. While still holding the odometer/trip odometer switch button depressed, turn the ignition switch to the ON position, but do not start the engine.
4. Release the odometer/trip odometer switch button.
5. The instrument cluster will simultaneously begin to illuminate all of the operational segments in the VFD unit and perform a bulb check of each operational LED indicator. The VFD segments and LED indicators remain illuminated as each gauge needle is swept to several calibration points and back. If a VFD segment or an LED indicator fails to illuminate, or if a gauge needle fails to sweep through the calibration points and back during this test, the instrument cluster must be replaced.
6. The actuator test is now completed. The instrument cluster will automatically exit the self-diagnostic mode and return to normal operation at the completion of the test. The actuator test will be aborted if the ignition switch is turned to the OFF position, or if a vehicle speed message indicating that the vehicle is moving is received from the PCM over the CAN data bus during the test.
7. Go back to STEP 1 to repeat the test, if necessary.

07 ThunderRoad

Disconnect and isolate the negative battery cable.
2. Remove the steering column opening cover. (Refer to 23 - BODY/INSTRUMENT PANEL/STEERING COLUMN OPENING COVER - REMOVAL)

3. Remove the screws (2) that secure the top of the instrument cluster bezel (1) to the instrument panel.
4. Using a trim stick C-4755 or equivalent, disengage the two retainer clips that secure the top of the instrument cluster bezel to the instrument panel.
5. Carefully disengage the instrument cluster bezel from the instrument panel opening and remove the bezel.

07 ThunderRoad

3. Remove the four screws (2) that secure the instrument cluster (1) to the instrument panel structural support (3).
4. Pull the instrument cluster rearward far enough to access and disconnect the three instrument panel wire harness connectors (2) from the connector receptacles (1), C1, C3 and C4 from right to left on the back of the cluster housing.
5. Remove the instrument cluster from the instrument panel.

Thanks for the info on how to run an instrument cluster check, I'll do that first thing tomorrow and get back with you.
The options are limited on this, no hands free device, no dvd player, stock radio without sat. It did come with Sentry Key but I don't have it. Anything else I can add let me know.

This is from the 07 service manual. The fuse location may not be in the same hole in an 06.

DESCRIPTION
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse that is disconnected within the Totally Integrated Power Module (TIPM) when the vehicle is shipped from the factory. Dealer personnel are to reconnect the IOD fuse in the TIPM as part of the new vehicle preparation procedures and then disconnect it again until new vehicle delivery to the customer.

A laser printed fuse layout map is integral to the TIPM cover to ensure proper fuse identification. The IOD fuse is a 20 ampere mini blade-type fuse. The fuse is secured within a black molded plastic fuse holder and puller unit that serves both as a tool for disconnecting and reconnecting the fuse in the TIPM cavity, and as a fuse holder that conveniently stores the fuse in the same cavity after it has been disconnected.

OPERATION
The term Ignition-Off Draw (IOD) identifies a normal condition where power is being drained from the battery with the ignition switch in the Off position. The IOD fuse feeds the memory and sleep mode functions for some of the electronic modules in the vehicle as well as various other accessories that require battery current when the ignition switch is in the Off position. The only reason the IOD fuse is disconnected is to reduce the normal IOD of the vehicle electrical system during new vehicle transportation and pre-delivery storage to reduce battery depletion, while still allowing vehicle operation so that the vehicle can be loaded, unloaded and moved as needed by both vehicle transportation company and dealer personnel.

The IOD fuse is disconnected from Integrated Power Module (IPM) fuse cavity # 51 when the vehicle is shipped from the assembly plant. Dealer personnel must reconnect the IOD fuse when the vehicle is being prepared for delivery in order to restore full electrical system operation. Once the vehicle is prepared for delivery, the IOD function of this fuse becomes transparent and the fuse that has been assigned the IOD designation becomes only another Fused B(+) circuit fuse.

The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery depletion when a vehicle is to be stored for periods not to exceed about thirty days. However, it must be remembered that disconnecting the IOD fuse will not eliminate IOD, but only reduce this normal condition. If a vehicle will be stored for more than about thirty days, the battery negative cable should be disconnected to eliminate normal IOD; and, the battery should be tested and recharged at regular intervals during the vehicle storage period to prevent the battery from becoming discharged or damaged.

The Sentry Key Immobilizer System (SKIS) is available as a factory-installed option on this vehicle. Vehicles equipped with this option can be readily identified by the illumination of the security indicator in the instrument cluster for about three seconds after the ignition switch is turned to the ON position as a SKIS bulb test.

The SKIS includes the following major components, which are described in further detail elsewhere in this service information:

Powertrain Control Module (1) - The Powertrain Control Module (PCM) is located in the engine compartment and provides the SKIS engine control logic. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/POWERTRAIN CONTROL MODULE - DESCRIPTION).
Security Indicator - A security indicator is integral to the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN). (Refer to 8 - ELECTRICAL/INSTRUMENT CLUSTER/SECURITY INDICATOR - DESCRIPTION).
Sentry Key Remote Entry Module (2) - The Sentry Key Remote Entry Module (SKREEM) (also known as the Wireless Control Module/WCM) is located on the right side of the steering column near the ignition lock cylinder housing and an integral molded plastic antenna ring circles the ignition lock cylinder like a halo. The SKREEM and its antenna are concealed beneath the steering column shrouds. Two SKREEM modules are available: one for vehicles equipped with Remote Keyless Entry (RKE) only, and one for vehicles equipped with RKE and SKIS.
Sentry Key Transponder (3) - The Sentry Key transponder is contained within the Remote Keyless Entry (RKE) transmitter on the ignition key.
Except for the Sentry Key transponders, which rely upon Radio Frequency (RF) communication, hard wired circuitry connects the SKIS components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the SKIS components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.

The Sentry Key Immobilizer System (SKIS) is designed to provide passive protection against unauthorized vehicle use by disabling the engine after about two seconds of running, whenever any method other than a valid Sentry Key is used to start the vehicle. The SKIS is considered a passive protection system because it is always active when the ignition system is energized and does not require any customer intervention. The SKIS uses Radio Frequency (RF) communication to obtain confirmation that the key in the ignition switch is a valid key for operating the vehicle. The microprocessor-based SKIS hardware and software also uses electronic messages to communicate with other electronic modules in the vehicle over the Controller Area Network (CAN) data bus. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/COMMUNICATION - OPERATION).

Pre-programmed Sentry Key transponders are provided with the vehicle from the factory. Each Sentry Key REmote Entry Module (SKREEM) (also known as the Wireless Control Module/WCM) will recognize a maximum of eight Sentry Keys. If the customer would like additional keys other than those provided with the vehicle, they may be purchased from any authorized dealer. These additional keys must be programmed to the SKREEM in the vehicle in order for the system to recognize them as valid keys. This can be done by the dealer using a diagnostic scan tool or, if Customer Learn programming is an available SKIS feature in the market where the vehicle was purchased, the customer can program the additional keys, as long as at least two valid Sentry Keys are already available. (Refer to 8 - ELECTRICAL/VEHICLE THEFT SECURITY - STANDARD PROCEDURE - TRANSPONDER PROGRAMMING).

The hard wired circuits between components related to the SKIS may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the SKIS or the electronic controls or communication between other modules and devices that provide some features of the SKIS. The most reliable, efficient, and accurate means to diagnose the SKIS or the electronic controls and communication related to SKIS operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

After reading the above, how could the truck have the system removed? Did you have the options list printed for the truck? I think it would be cheaper to fix the sentry key system than remove it. The sentry key system is not the vehicle theft security system. The two systems work together but the sentry key can be ordered in the truck without the security system.

gunnie

Not really wanting to remove the sentry key system, only attempting to eliminate all items that could be causing my battery drain, which is a continuous cycle of 1.67 amps for 30 seconds to a 1.2 amps for the same length of time then to .3 amps for only 10 seconds, It repeats this process indefinitely. I'm just not knowledgeable enough to make a determination of which component is drawing the power, so I'm trying to eliminate them one at a time.
thanks for the input I appreciate the help.

gunnie

tried the instrument cluster check as suggested and everything seems to be fine, the only light left on afterwards was check engine. this can't be that difficult, just something I'm missing from lack of electrical expertise. I guess the next step is to try to put the amp clamp over the wires feeding the sentry key and cluster to see if maybe I can tell that way.

gunnie

unplugged the inst cluster and radio and the draw went to zero, plugged the inst cluster back in and the fluctuation started again only up to 1.0 then down to .7 then to zero for 8-10 seconds like attempting sleep mode, then the process started all over again. with the radio plugged in also the readings are slightly higher 1.4 to .9 then to zero. with only the radio plugged in without the inst cluster it does draw like .2 or .3 amps. is this normal and does it sounds to you guys like the cluster is bad? if so can I get a used cluster? I bet that thing is way expensive from Dodge
thanks

mastertech

hi guys new here. i think your problem might be your windshield wiper motor because your power is pulsating. ive seen it a few times. tracking it threw the iod fuse isnt going to work very well

07 ThunderRoad

I agree. This is a list of circuits the cluster is connected to. First line is connector and its color and the number of pins. Numbered lines are the pin numbers, circuit number, wire size, wire color, name of circuit. The cluster is the source of power to some of the circuits or monitors that circuit for the gauges and message lights. The wipers will park with the ignition off, this is a good deduction that the wiper motor may be trying to park.

ok guys now I'm confused, so you're thinking maybe something else is waking the computer but I'm seeing the draw through the grey/red stripe wire feeding the cluster? It is the center connector, I can go count the pins if you want me to because I left the instr cluster and radio unplugged. One thing I did notice today, when I had the interior lights turned off and the doors open, when the drain went to zero on the amp clamp around the grey/red stripe wire the speedo mileage and door ajar light would go out, for about 8-10 seconds but when the draw went back to 1.0 amps they were back on.
Where do I go next with this? Start unhooking everything associated with this center connector? I also want to add I pulled every fuse when this started and the only one that changed anything was the IOD fuse.
