Diagnostic Test

WARNING: This page is about a different variant/trim than selected.
  1. CHECK FOR TCM TIPM DTCS 
    1. With the scan tool, read DTCs.

      Are there any TIPM TCM Power Control Circuit DTCS present?

      Yes 

      No 

      • Go to step  2
  2. CHECK TO SEE IF DTC P0883 IS CURRENT 
    1. With the scan tool, check the Starts Since Set counter.
      NOTE: This counter only applies to the last DTC set.

      Is the Starts Since Set counter set to 0?

      Yes 

      • Go to step  3

      No 

      • Go to step  6
  3. (T16) TRANSMISSION OUTPUT CIRCUIT SHORTED TO VOLTAGE

    1. Turn the ignition off to the lock position.
    2. Disconnect the PCM C4 harness connector and connect the PCM Pinout Box 8815.
    3. Disconnect the TIPM C10 harness connector.
      CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install the PCM Pinout Box 8815 to perform diagnosis.
    4. Ignition on, engine not running.
    5. Measure the voltage of the (T16) Transmission Control Output circuits in the PCM Pinout Box 8815.

      Is the voltage above 0.5 of a volt on any (T16) Transmission Control Output circuit?

      Yes 

      • Go to step  4

      No 

      • Go to step  5
  4. CHECK THE TRANSMISSION SOLENOID/TRS ASSEMBLY

    1. Turn the ignition off to the lock position.
    2. Disconnect the Transmission Solenoid/TRS Assembly harness connector.
    3. Ignition on, engine not running.
    4. Measure the voltage of the (T16) Transmission Control Output circuits in the PCM Pinout Box 8815.

      Is the voltage above 0.5 of a volt?

      Yes 

      No 

  5. CHECK THE (T515) TRANSMISSION CONTROL CIRCUIT FOR A SHORT TO VOLTAGE 
    Fig 3: Checking Transmission Control Circuit

    1. Measure the voltage of the (T515) Transmission Control circuit.

      Is the voltage above 0.5 of a volt?

      Yes 

      No 

      • Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace and program the PCM in accordance with the Service Information. With the scan tool, perform Quick Learn.
      • Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure .
  6. CHECK WIRING AND CONNECTORS 
    1. The conditions necessary to set this DTC are not present at this time.
    2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
    3. Wiggle the wires while checking for shorted and open circuits.
    4. With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.

      Where there any problems found?

      Yes 

      No
