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.

CHECK IF THE DTC IS CURRENT
1. Start the engine in park.
2. Raise the drive wheels off of the ground.
  WARNING:
  Properly support the vehicle.
3. Firmly apply the brakes and place the transmission selector in drive.
  WARNING:
  Be sure to keep hands and feet clear of rotating wheels.
4. Release the brakes and allow the drive wheels to spin freely.
  NOTE:
  The drive wheels must be turning at this point.
5. With the scan tool, read the Transfer RPM
  Is the Transfer RPM below 100?
  
  Yes
  - Go To 2
  No
  - Go To 8
CHECK THE PCM AND WIRING USING 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 Transmission Simulator (special tool #8333B, Simulator, Transmission) and the Electronic Transmission Adapter kit.
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, read the Input and Transfer RPM.
  Does the Input RPM read 3000 and the Transfer RPM read 1250 (within 50 RPM)?
  
  Yes
  - Replace the Transfer Speed Sensor in accordance with the Service Information. Refer to SENSOR, SPEED, INPUT, REMOVAL .
  - Perform the 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 3
CHECK THE (T85) TRANSFER SPEED SIGNAL CIRCUIT FOR AN OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the PCM C1 harness connector.
3. Disconnect the Transfer Speed Sensor harness connector.
4. Measure the resistance of the (T85) Transfer Speed Signal circuit between the appropriate terminal of the PCM C1 harness connector and the Transfer Speed Sensor harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T85) Transfer Speed Signal circuit for an open.
  - Perform the 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 4
CHECK THE (T13) SPEED SENSOR GROUND CIRCUIT FOR AN OPEN

1. Measure the resistance of the Speed Sensor Ground circuit between the appropriate terminal of the PCM C1 harness connector and the Transfer Speed Sensor harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T13) Speed Sensor Ground circuit for an open.
  - Perform the 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 5
CHECK THE (T85) TRANSFER SPEED SENSOR SIGNAL CIRCUIT FOR A SHORT TO GROUND

1. Measure the resistance between ground and the (T85) Transfer Speed Signal circuit.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the (T85) Transfer Speed Signal circuit for a short to ground.
  - Perform the 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 6
CHECK THE (T85) TRANSFER SPEED SENSOR SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE

1. Remove the PCM/TCM relay and with a fused jumper wire, jumper the Transmission Control Output to B(+).
2. Ignition on, engine not running.
3. Measure the voltage of the (T85) Transfer Speed Signal circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T85) Transfer Speed Signal circuit for a short to voltage.
  - Perform the 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 7
CHECK THE (T13) SPEED SENSOR GROUND CIRCUIT FOR A SHORT TO VOLTAGE

NOTE:
Jumper must still be in place.
1. Measure the voltage of the (T13) Speed Sensor Ground circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T13) Speed Sensor Ground circuit for a short to voltage.
  - Perform the 62TE VERIFICATION TEST. Refer to 62TE 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 62TE 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 wiring and connectors 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 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 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Test Complete.
