Diagnostic Test

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FOR TCM TIPM DTCS 
    1. Remove the PCM/TCM Relay and install a known good relay.

      Is the Starts Since Set counter set to 0?

      Yes 

      No 

      • Go To  2
  2. CHECK 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  3

      No 

      • Go To  6
  3. CHECK THE (T16) TRANSMISSION OUTPUT CIRCUIT FOR A SHORT TO VOLTAGE

    1. Turn the ignition off to the lock position.
    2. Disconnect the PCM C1 harness connector.
    3. Remove the PCM/TCM Relay.
    4. Ignition on, engine not running.
    5. Measure the voltage of the (T16) Transmission Control Output circuits in the PCM C1 harness connector.

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

      Yes 

      • Go To  4

      No 

      • Go To  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 C1 harness connector.

      Is the voltage above 0.5 of a volt?

      Yes 

      • Repair the (T16) Transmission Control Output circuit for a short to voltage.
      • Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST  .

      No 

  5. CHECK THE (T15) TRANSMISSION CONTROL CIRCUIT FOR A SHORT TO GROUND 
    Fig 3: Checking Transmission Control Circuit For A Short To Ground
    GC0150051Courtesy of CHRYSLER GROUP, LLC
    1. Measure the resistance of the (T15) Transmission Control circuit between ground and the PCM C1 harness connector.

      Is the resistance below 100k Ohms?

      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. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL . With the scan tool, perform Quick Learn.
      • Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST  .
  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
