Diagnostic Test

WARNING: This page is about a different variant/trim than selected.
  1. CHECK IF THE DTC IS CURRENT 
    1. With the scan tool, check the Starts Since Set counter for P0882.
      NOTE: This counter only applies to the last DTC set.

      Is the Starts Since Set counter equal to 0?

      Yes 

      • Go to  2

      No 

      • Go to  9
  2. (A104) FUSED B(+) CIRCUIT OPEN

    1. Turn the ignition off to the lock position.
    2. Remove the Transmission Control Relay.
      NOTE: Check connectors - Clean/repair as necessary.
    3. Ignition on, engine not running.
    4. Using a 12-volt test light connected to ground, check the (A104) Fused B(+) circuit in the Transmission Control Relay connector.
      NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

      Does the test light illuminate brightly?

      Yes 

      • Go to  3

      No 

  3. (Z915) TRANSMISSION CONTROL RELAY GROUND CIRCUIT OPEN

    1. Turn the ignition off to the lock position.
    2. Using a 12-volt test light connected to 12-volts, check the (Z915) Transmission Control Relay Ground circuit in the Transmission Control Relay connector.

      Does the test light illuminate brightly?

      Yes 

      • Go to  4

      No 

  4. TRANSMISSION CONTROL RELAY 
    1. Install a substitute relay in place of the Transmission Control Relay.
    2. Start the vehicle.
    3. With the scan tool, check transmission DTCs.

      Did the DTC P0888 reset?

      Yes 

      • Go to  5

      No 

  5. (T16) TRANSMISSION CONTROL RELAY OUTPUT CIRCUIT OPEN

    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 Transmission Solenoid/TRS Assembly 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. Connect a jumper wire between the (A104) Fused B(+) circuit and the Transmission Control Relay Output circuit in the Transmission Control Relay connector.
    5. Ignition on, engine not running.
    6. Using a 12-volt test light connected to ground, check all four (T16) Transmission Control Relay Output circuits in the PCM C4 harness connector and Transmission Solenoid/TRS Assembly harness connector.

      Does the test light illuminate brightly on all four (T16) Transmission Control Relay Output circuits?

      Yes 

      • Go to  6

      No 

  6. (T16) TRANSMISSION RELAY OUTPUT CIRCUIT SHORTED TO GROUND 
    Fig 4: Checking Transmission Control Relay Output Circuit For Short To Ground

    1. Turn the ignition off to the lock position.
    2. Measure the resistance between ground and the (T16) Transmission Control Relay Output circuit.

      Is the resistance below 5.0 Ohms?

      Yes 

      No 

      • Go to  7
  7. (T15) TRANSMISSION CONTROL RELAY CONTROL CIRCUIT SHORTED TO GROUND 
    Fig 5: Checking Transmission Control Relay Control Circuit For Short To Ground
    GC0106942Courtesy of CHRYSLER LLC
    1. Measure the resistance between ground and the (T15) Transmission Control Relay Control circuit.

      Is the resistance below 5.0 Ohms?

      Yes 

      No 

      • Go to  8
  8. (T15) TRANSMISSION CONTROL RELAY CONTROL CIRCUIT OPEN 
    Fig 6: Checking Transmission Control Relay Control Circuit For Open
    GC0106943Courtesy of CHRYSLER LLC
    1. Measure the resistance of the (T15) Transmission Control Relay Control circuit between the Transmission Control Relay connector and the appropriate terminal of the PCM Pinout Box 8815.

      Is the resistance above 5.0 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 appropriate service information. With the scan tool, perform Quick Learn.
      • Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  9. CHECK THE 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 

      • Test Complete.
