SUBJECT:
TIPM Flash - DTC's Indicating Short Circuits In The Wiring On The Trailer Or No Engine Crank With DTC P1277 - Starter Control Circuit 2 Low
OVERVIEW:
This bulletin involves a discussion and reprogramming of the Totally Integrated Power Module (TIPM).
MODELS:
2006
(DR/DH/D1)
Ram Truck
NOTE:
This bulletin applies to vehicles built prior to April 03, 2006 (MDH 0403XX).
SYMPTOM/CONDITION:
Customer may experience any of the following TIPM Diagnostic Trouble Codes (DTC's):
B166B - Left Trailer Tow Lamp Control Circuit Low. Trailer harness left lamp circuit is shorted to ground.
B166C - Left Trailer Tow Lamp Control Circuit High. Trailer harness left lamp circuit is shorted to battery voltage.
B178C - Left Trailer Tow Lamp Control Circuit Over Current. Trailer harness left lamp circuit is intermittently grounding.
B166F - Right Trailer Tow Lamp Control Circuit Low. Trailer harness right lamp circuit is shorted to ground.
B1670 - Right Trailer Tow Lamp Control Circuit High. Trailer harness right lamp circuit is shorted to battery voltage.
B166E - Right Trailer Tow Lamp Control Circuit Over Current. Trailer harness right lamp circuit is intermittently grounding.
B1667 - Back Up Lamp Feed Low. Trailer harness back up circuit is shorted to ground.
B2215 - Front Control Module Internal (TIPM). An internal fault code counter has exceeded its limit of 250 counts and one or more electrical outputs
controlled by the TIPM have been disabled.
P1277 - Starter Control Circuit 2 Low (TIPM). The output feed current to the starter solenoid has exceeded the upper current limit of 75 amps. This may
result in a no-crank condition.
DISCUSSION:
DTC's B1667, B166B, B166E, B166F, B178C and B2215:
1.
These DTC's indicate that a (hard or intermittent) short circuit to GROUND exists in the wiring of one or more of the TRAILER electrical harness
circuits.
2.
The TIPM retries the output on each ignition cycle or request (brake or turn signal activation) in an attempt to enable the output in case the fault is
intermittent.
3.
DTC's B1667, B166B, B166E, B166F, and B178C may occur individually or in combination with each other.
4.
For the two over current DTC's, B166E and B178C, the fault is set when the TIPM has detected electrical loads on the circuit greater than 15
