Pinpoint Test K : DTC P0702, P0882, P0883

WARNING: This page is about a different variant/trim than selected.
  1. Refer to Transmission Controls for schematic and connector information.

    Normal Operation and Fault Conditions 

    The PCM monitors the supplied voltage and sets a DTC if supply voltage rises below or above threshold.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    PCM P0702:00 Transmission Control System Electrical: No Sub Type Information Sets in continuous memory and during the on-demand self-test when the PCM detects the supply voltage is greater than 16 volts.
    PCM P0882:00 TCM Power Input Signal Low: No Sub Type Information Sets in continuous memory and during the on-demand self-test when the PCM detects the supply voltage is lower than 9 volts.
    PCM P0883:00 TCM Power Input Signal High: No Sub Type Information Sets in continuous memory and during the on-demand self-test when the PCM detects the supply voltage is greater than 16 volts.

    Possible Sources 

    • Charging system concern
    • High resistance ground condition
    • Low voltage to the PCM

  2. NOTE: DTC U3003:17 may be stored in the module memory due to past battery charging or vehicle jump starting events.

  3. K1 RECHECK FOR THE HIGH VOLTAGE DTC (DIAGNOSTIC TROUBLE CODE) IN THE SUSPECT MODULE

    • Ignition OFF.

    • Ignition ON.

    • Using a diagnostic scan tool, clear the DTC for the PCM.

    • Wait 10 seconds.

    • Using a diagnostic scan tool, carry out the PCM self-test.

    Are DTCs P0702, P0882, P0883 still present? 

    Yes  GO to  K2
    No  The system is operating correctly at this time. The DTC may have been set previously during battery charging or while jump starting the vehicle.

  4. K2 CHECK FOR HIGH VOLTAGE DIAGNOSTIC TROUBLE CODES (DTCS) SET IN OTHER MODULES

    • Ignition ON.

    • Using a diagnostic scan tool, retrieve the Continuous Memory Diagnostic Trouble Codes (CMDTCs).

    Are any charging or over-voltage related voltage Diagnostic Trouble Codes (DTCs) present in multiple modules? 

    Yes  DIAGNOSE the overcharging condition. REFER to Charging System .
    No  GO to  K3

  5. K3 CHECK THE PCM SUPPLY VOLTAGE

    • Ignition OFF.

    • Disconnect PCM CXXX.

    • Measure:

    Are the voltages greater than 11 volts? 

    Yes  GO to  K4
    No  REPAIR the circuit in question.

  6. K4 CHECK THE PCM GROUND CIRCUITS

    • Ignition OFF.

    • Measure:

    Are the resistances less than 3 ohms? 

    Yes  Refer to PCM GUIDED ROUTINE TESTING
    After programming the new PCM, CARRY OUT the transmission strategy download. REFER to: Transmission Strategy Download .
    No  REPAIR the circuit in question.
