P0201 Generic Injector Circuit / Open - Cylinder 1
DOES ANYONE KNOW WHAT THIS ONE MEANS AND THIS ONE
P0602 Generic Powertrain Control Module Programming Error
i have gotton the 602 for some time i just figured it was another by product of the tst. but have never got the 201 before and i am wondering if it might be the culprit of some white smoke i have been noticing?
any answers?

Update your smarty to get rid of the 602 code. as for the 201 it could be a bad injector or bad wiring. Need to get the dvom out to know for sure.

i have not updated smarty since i bought back in october of last year they have probably changed a little since then

TEST ACTION APPLICABILITY
1 With the DRBIIIt, read DTCs.
Are all 6 of the injector DTC’s (P0201 - P0206) present?
ENGINE- 5.9L
CUMMINS 24V
DIESEL
Yes ! Go To 2
No ! Go To 3
2 Inspect wiring harness for signs of multiple open circuits between the ECM and the
injector pass through connectors. Inspect the wiring harness between the pass
through connectors to the injectors.
Are there open circuits in the wiring harness?
ENGINE- 5.9L
CUMMINS 24V
DIESEL
Yes ! Repair or replace the open connectors or wiring.
No ! Go To 3
3 Turn the ignition off.
Disconnect the pigtail nuts from the suspect injector. Using an Ohmmeter, check the
resistance between the solenoid posts of the injector.
NOTE: Be sure to zero the ohm meter prior to checking the injector circuit.
Is the resistance less than 1 ohm and greater than 0 ohms?
ENGINE- 5.9L
CUMMINS 24V
DIESEL
Yes ! Go To 4
No ! Replace the fuel injector.
4 Connect the pigtail nuts for the suspect injector.
Disconnect the injector harness connector for the suspect injector.
Measure the resistance of the injector harness circuit between the high side driver
pin and the low side driver pin for the suspect injector at the injector harness
connector.
NOTE: Be sure to zero the ohm meter prior to checking the injector circuit.
Is the resistance less than 1 ohm and greater than 0 ohms?
ENGINE- 5.9L
CUMMINS 24V
DIESEL
Yes ! Go To 5
No ! Replace or repair the injector harness.
5 Disconnect the ECM harness connectors.
Disconnect the Injector harness connector.
Check connectors - Clean/repair as necessary.
Measure the resistance of the Bank 1 high side driver wire between the ECM
connector and the injector harness connector.
Is the resistance less than 10 Ohms?
ENGINE- 5.9L
CUMMINS 24V
DIESEL
Yes ! Go To 6
No ! Replace or repair the open engine harness.

that sounds pretty thorough, even if everything is ok i could probly find something to replace after going through that check list. thanks fo the info

Everything won't be o.k. if it sets that code. The diagnostic tree will guide you to the problem.

The TST harness can also set the code
