For a complete wiring diagram Refer to Section 8W.

Theory of Operation


The Transmission Control Module request from the ECM/PCM to change the torque of the engine to avoid possible damage to the transmission.


  • When Monitored:

    Ignition on with system voltage between 9.0 and 16 volts.

    No PCM/ECM CAN Bus DTCs present.

  • Set Condition:

    When the TCM receives an implausible engine torque signal from the PCM over the CAN Bus for a period of 1.0 second.


Possible Causes
 
FCM/TIPM CAN BUS DTCS PRESENT
 
ENGINE MODULE DTCS PRESENT
 
POWERTRAIN CONTROL MODULE
 
TRANSMISSION CONTROL MODULE
