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 TO SEE IF DTC IS CURRENT
1. With the scan tool, view DTCs.
  Is the status Active for this DTC or is Starts Since Set counter 2 or less?
  
  Yes
  - Go To 2
  No
  - Go To 6
CHECK THE PCM AND WIRING WITH THE TRANSMISSION SIMULATOR
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 (special tool #8333B, Simulator, Transmission) and the Electronic Transmission Adapter kit.
4. Ignition on, engine not running.
5. With the Transmission Simulator, turn the Input/Output switch to OFF.
6. With the scan tool, monitor the TRANS TEMP VOLTS while turning the Thermistor Voltage switch to all three positions on the Transmission Simulator.
7. Compare the scan tool readings with the numbers listed on the Transmission Simulator.
  Do the readings on the Transmission Simulator match the scan tool readings ± 0.2 of a volt?
  
  Yes
  - Replace the Transmission Temperature Sensor (in the TRS Assembly) in accordance with the Service Information. Refer to SENSOR, TRANSMISSION RANGE, REMOVAL .
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to 40/41 TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 3
CHECK THE (T54) TRANSMISSION TEMPERATURE SIGNAL CIRCUIT FOR AN OPEN
1. Turn the ignition off to the lock position.
2. Disconnect the (special tool #8333B, Simulator, Transmission) and the Electronic Transmission Adapter kit.
3. Disconnect the PCM C1 harness connector.
4. Disconnect the TRS harness connector.
5. Measure the resistance of the Transmission Temperature Signal circuit between the PCM C1 harness connector and the TRS harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the Transmission Temperature Signal circuit for an open.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to 40/41 TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 4
CHECK THE (K900) SENSOR GROUND CIRCUIT FOR AN OPEN
1. Disconnect the PCM C2 harness connector.
2. Measure the resistance of the (K900) Sensor Ground circuit between the PCM C2 harness connector and the TRS harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (K900) Sensor Ground circuit for an open.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to 40/41 TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 5
CHECK THE (T54) TRANSMISSION TEMPERATURE SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE
1. Ignition on, engine not running.
2. Measure the voltage of the (T54) Transmission Temperature Signal circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T54) Transmission Temperature Signal circuit for a short to voltage.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to 40/41 TE 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 TRANSMISSION VERIFICATION TEST. Refer to 40/41 TE TRANSMISSION VERIFICATION TEST .
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.
5. Check for any Service Information Tune-ups or Service Bulletins for any possible causes that may apply.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to 40/41 TE TRANSMISSION VERIFICATION TEST .
  No
  - Test Complete.
