i was wondering if anybody has had trouble with their door locks? my locks currently will unlock (all doors) with the door lock button and the factory remote, but will not lock unless manualy locking the doors. dose anybody know what i have to replace?

 

If you are talking that once you turn off the truck and open your door, the others do not unlock then you can change that via the turn the key forward, backward x times and perssing the door lock/unlock button. My 07 was this way and it was a pain getting the kids out of the back. Look in your owners manual and it should be right there. Easy to do. The way mine works now is once a door in the front is opened, all the doors unlock.

 

no it dosent matter if the truck is running or not or where the key is. the locks wont lock unless they are manually pushed down by hand, but they can be unlocked by either the remote or the unlock button.

 

I guess I'm not exactly understanding what you want...

Do you want your doors to lock automatically when you hit a certain speed (think my 07 is like 15 mph) or something different?

 

well i want to be able to lock the doors with the remote or the lock button.
the locks used to lock when the truck would start moving like 10-15 mph.
the problem is i have to use the keys to get in and after everybody gets out i have to manualy lock all the doors by hand instead of using the lock button/switch or remote.

 

Does the door switch work? To LOCK the doors from the inside?

Im guessing the actuators are out(common thing on foxbody mustangs)
BUT, I dont see why all of them would go out at the same time, and I also dont see why they would still unlock, but not lock.
It might be a job for the dealership crooks

 

in my megacab i have to press the lock button ATLEAST three times for it to lock the other doors. I;m gonna take it into the shop for the reflash just to see if it would help.

 

the switch will unlock the doors and the remote will unlock the doors, but they(switch and remote) will not lock them. no matter how manny times i push them.

 

DIAGNOSIS AND TESTING - POWER LOCKS
The most reliable, efficient, and accurate means to diagnose the power lock system requires the use of a DRBIII® scan tool and the proper Diagnostic Procedures manual. The DRBIII® scan tool can provide confirmation that the PCI data bus is functional, that all of the electronic modules are sending and receiving the proper messages on the PCI data bus, and that the power lock motors are being sent the proper hard wired outputs by the relays for them to perform their power lock system functions.

Following are tests that will help to diagnose the hard wired components and circuits of the power lock system. However, these tests may not prove conclusive in the diagnosis of this system. In order to obtain conclusive testing of the power lock system, the Programmable Communications Interface (PCI) data bus network and all of the electronic modules that provide inputs to, or receive outputs from the power lock system components must be checked.

The instrument cluster will set Diagnostic Trouble Codes (DTC) for the power lock system.

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.

PRELIMINARY DIAGNOSIS
As a preliminary diagnosis for the power lock system, note the system operation while you actuate both the Lock and Unlock functions with the power lock switches and with the Remote Keyless Entry (RKE) transmitter. Then, proceed as follows:

If the entire power lock system fails to function with either the power lock switches or the RKE transmitter, check the fused B(+) fuse in the Integrated Power Module (IPM).
If the power lock system functions with both power lock switches, but not with the RKE transmitter, proceed to diagnosis of the Remote Keyless Entry (RKE) system. (Refer to 8 - ELECTRICAL/POWER LOCKS/KEYLESS ENTRY TRANSMITTER - DIAGNOSIS AND TESTING) or (Refer to 8 - ELECTRICAL/POWER LOCKS/REMOTE KEYLESS ENTRY MODULE - DIAGNOSIS AND TESTING).
If the power lock system functions with the RKE transmitter, but not with one or both power lock switches, proceed to diagnosis of the door lock switches. (Refer to 8 - ELECTRICAL/POWER LOCKS/POWER LOCK SWITCH - DIAGNOSIS AND TESTING).
If the driver side power lock switch operates only the driver side front door power lock motor, but all other power lock motors operate with the passenger side power lock switch or the RKE transmitter, use a DRBIII® scan tool and the appropriate diagnostic information to diagnose the Programmable Communications Interface (PCI) data bus.
If only one power lock motor fails to operate with both power lock switches and the RKE transmitter, proceed to diagnosis of the power lock motor. (Refer to 8 - ELECTRICAL/POWER LOCKS/POWER LOCK MOTOR - DIAGNOSIS AND TESTING).

 

Sorry, got a little ahead of myself. The doors will not lock anytime the keys are in the ignition. You may try to lube the ignition lock cylinder. There is a possibility that the key in switch is stuck. Does the chime sound like they keys are in the ignition all the time? ( keys out, ign switch off, and door open?) That would be the first thing I would try.

 

the chime works like it should. truck off key in the ignition,door open chime starts until i pull the key out. i am going to check the fuse right now.

 

Fuse is more than likely fine because they work , all be it partially! Next thing to check would be to unplug one or the other door lock switches. Then see if they work. One or more switches may be bad. Try the cluster test. Hold the TRIP/ODO butt and turn the key on. Any codes will be in the odo screen. Have a pen handy, there could be more than one.

 

the fuses are good, must need scanned the switch and remote will open the doors but won't lock them.

 

well i held the trip thing in and turned it on and it said c code then AB 00, then 00 00. anybody know what that means?

 

AB= TCM messages not received
00= 0 key cycles since set

00-00= end of codes.
