Diagnostic Test

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

PCM AND WIRING
1. Turn the ignition off to the lock position.
2. Remove the Starter Relay.
  CAUTION:
  Removal of the Starter Relay will prevent the vehicle from being started in gear.
  
  WARNING:
  The Starter Relay must be removed from the PDC. Failure to do so may result in possible serious or fatal injury.
  
  NOTE:
  Failure to remove the Starter Relay can cause a Transmission - No Response condition.
3. Install the Transmission Simulator (special tool #8333B, Simulator, Transmission) and the Electronic Transmission Adapter kit.
  NOTE:
  Check connectors - Clean/repair as necessary.
4. Ignition on, engine not running.
5. With the Transmission Simulator, set the "Input/Output Speed" switch to "ON" and the rotary switch to the "3000/1250" position.
6. With the scan tool, monitor the Input and Output Speed Sensor readings.
  Does the Input Speed read 3000 rpm and the Output Speed read 1250 rpm (± 50 rpm)?
  
  Yes
  - Go To 2
  No
  - Go To 3

1. Turn the ignition off to the lock position.
2. Disconnect the Transmission Simulator (special tool #8333B, Simulator, Transmission) and the Electronic Transmission Adapter kit.
3. Disconnect the PCM C1 harness connector.
4. Measure the resistance of the (T13) Speed Sensor Ground circuits between the PCM C1 harness connector and the Input and Output Speed Sensor harness connectors and the TRS harness connector.
  Is the resistance above 5.0 Ohms on any circuit(s)?
  
  Yes
  - Repair the (T13) Speed Sensor Ground circuit(s) for an open.
  - Perform the 40/41TE VERIFICATION TEST. Refer to 40/41TE TRANSMISSION VERIFICATION TEST .
  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. Check for Service Information Tune-ups or Service Bulletins for any possible causes that may apply. 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 40/41TE VERIFICATION TEST. Refer to 40/41TE TRANSMISSION VERIFICATION TEST .
CHECK THE WIRING AND CONNECTORS
1. The conditions necessary to set the 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.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the 40/41TE VERIFICATION TEST. Refer to 40/41TE TRANSMISSION VERIFICATION TEST .
  No
  - Test Complete.
