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.

CHECK IF RELATED TCM DTCS ARE PRESENT
1. With the scan tool, read DTCs
  Are there any TCM Power Input DTCs present also?
  
  Yes
  - Refer to the DIAGNOSTIC CODE INDEX and perform the appropriate transmission diagnostic procedure.
  No
  - Go To 2
CHECK FOR LOSS OF PRIME DTC
1. With the scan tool, check for other DTCs.
  Is the DTC P0944 present also?
  
  Yes
  - Refer to the DIAGNOSTIC CODE INDEX and perform the appropriate transmission diagnostic procedure.
  No
  - Go To 3
CHECK TO SEE IF P0841 IS CURRENT
1. With the scan tool, view DTCs.
  Is the status active for this DTC or is the Starts Since Set counter 2 or less?
  
  Yes
  - Go To 4
  No
  - Go To 8
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.
4. Ignition on, engine not running.
5. With the Transmission Simulator, turn the Pressure Switch selector to L/R.
6. With the scan tool, monitor the L/R Pressure Switch state while pressing the Pressure Switch Test button on the Transmission Simulator.
  Did the L/R Pressure Switch state change?
  
  Yes
  - Replace the Transmission Solenoid/TRS Assembly in accordance with the Service Information. Refer to ASSEMBLY, TRANSMISSION SOLENOID AND PRESSURE SWITCH, REMOVAL .
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 5
(T50) L/R PRESSURE SIGNAL CIRCUIT OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the PCM C1 harness connector.
3. Disconnect the Transmission Solenoid/TRS Assembly harness connector.
4. Measure the resistance of the (T50) L/R Pressure Signal circuit from the appropriate terminal of the PCM C1 harness connector and the Transmission Solenoid/TRS Assembly harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T50) L/R Pressure Signal circuit for an open.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 6
(T50) L/R PRESSURE SIGNAL CIRCUIT SHORTED TO GROUND

1. Measure the resistance between ground and the (T50) L/R Pressure Signal circuit.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the (T50) L/R Pressure Signal circuit for a short to ground.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 7
(T50) L/R PRESSURE SIGNAL CIRCUIT SHORTED TO VOLTAGE

1. Remove the Transmission Control Relay.
2. Connect a jumper wire between the (A104) B (+) circuit and (T16) Transmission Control Relay Output circuit.
3. Ignition on, engine not running.
4. Measure the voltage of the (T50) L/R Pressure Signal circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T50) L/R Pressure Signal circuit for a short to voltage.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Replace and program the Powertrain Control Module 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 .
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 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Test Complete.
