Diagnostic Test

WARNING: This page is about a different car, the 2013 Dodge Avenger and 2013 Chrysler 200. However, it is still accessible from the selected car via links, so may be relevant.

CHECK FOR RELATED TRANSMISSION DTCS
1. With the scan tool, read Transmission DTCs.
  Are there any TCM Power Input or Transmission Control Relay DTCs present also?
  
  Yes
  - Refer to the DIAGNOSTIC CODE INDEX and perform the appropriate diagnostic procedure.
  No
  - Go To 2
CHECK FOR LOSS OF PRIME DTC
1. With the scan tool, check for other Transmission DTCs.
  Is the DTC P0944 present also?
  
  Yes
  - Refer to the DIAGNOSTIC CODE INDEX and perform the appropriate diagnostic procedure.
  No
  - Go To 3
CHECK IF THE DTC IS CURRENT
1. With the scan tool, view DTCs.
  Is the status Active or is the Starts Since Set counter 2 or less for this DTC?
  
  Yes
  - Go To 4
  No
  - Go To 8
CHECK THE PCM AND WIRING WITH THE TRANSMISSION SIMULATOR
1. Turn the ignition off to the lock position.
2. Remove the Ignition Switch Feed fuse from the TIPM.
  CAUTION:
  Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being started in gear.
  
  WARNING:
  The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in possible serious or fatal injury.
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, turn the Pressure Switch selector to 2/4.
6. With the scan tool, monitor the 2/4 Pressure Switch state while pressing the Pressure Switch Test button on the Transmission Simulator.
  Did the 2/4 Pressure Switch state change?
  
  Yes
  - Replace the Transmission Solenoid/Pressure Switch Assembly in accordance with the Service Information.
  - Perform the 40/41TE VERIFICATION TEST. Refer to 40/41TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 5
CHECK THE (T47) 2/4 PRESSURE SIGNAL CIRCUIT FOR AN OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the PCM C1 harness connector.
3. Disconnect the Transmission Simulator (special tool #8333B, Simulator, Transmission) and the Electronic Transmission Adapter kit.
4. Measure the resistance of the (T47) 2/4 Pressure Signal circuit between the PCM C1 harness connector and the Transmission Solenoid/Pressure Switch Assembly harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T47) 2/4 Pressure Signal circuit for an open.
  - Perform the 40/41TE VERIFICATION TEST. Refer to 40/41TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 6
CHECK THE (T47) 2/4 PRESSURE SIGNAL CIRCUIT FOR A SHORT TO GROUND

1. Measure the resistance between ground and the (T47) 2/4 Pressure Signal circuit.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the (T47) 2/4 Pressure Signal circuit for a short to ground.
  - Perform the 40/41TE VERIFICATION TEST. Refer to 40/41TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 7
CHECK THE (T47) 2/4 PRESSURE SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE

Courtesy of CHRYSLER GROUP, LLC
1. Ignition on, engine not running.
2. With the scan tool under TIPM, actuate the Transmission.
3. Measure the voltage of the (T47) 2/4 Pressure Signal circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T47) 2/4 Pressure Signal circuit for a short to voltage.
  - 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. 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.
