Diagnostic Test

WARNING: This page is about a different variant/trim than selected.

CHECK FOR RELATED DTCS
1. With the scan tool, check transmission DTCs.
  Are there any Transmission Control Relay or TCM Power Input DTCs present?
  
  Yes
  - See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Diagnosis and Testing and perform the appropriate diagnostic procedure.
  No
  - Go to 2
CHECK THE WIRING AND CONNECTORS
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 Transmission Simulator 8333A.
4. Ignition on, engine not running.
5. With the scan tool, actuate the MS Solenoid.
6. Monitor the MS Solenoid LED on the Transmission Simulator.
  Did the MS Solenoid LED on the Transmission Simulator blink on and off?
  
  Yes
  - Go to 3
  No
  - Go to 5
CHECK THE TRANSMISSION SOLENOID/TRS ASSEMBLY
1. With the scan tool, continue to actuate the MS Solenoid for the period of two minutes with the Transmission Simulator still connected.
2. After two minutes of actuation, with the scan tool, stop the actuation and check for transmission DTCs.
  Did the DTC P2706 reset during the actuation test?
  
  Yes
  - Go to 5
  No
  - Go to 4
WIGGLE TEST WITH TRANSMISSION SIMULATOR
1. With the Transmission simulator still connected, continue to actuate the 4C solenoid for another two minutes while wiggling the related wiring harness and connectors.
2. With the scan tool, stop the actuation and check for transmission DTCs.
  Did the DTC P0770 reset during the actuation test?
  
  Yes
  - Repair wiring harness or connectors as necessary.
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Replace the Transmission Solenoid/TRS Assembly in accordance with the appropriate service information.
    NOTE: Do NOT replace the entire Valve Body.
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
CHECK THE (T140) MS SOLENOID CONTROL CIRCUIT FOR A SHORT TO ANOTHER CIRCUIT

1. Turn the ignition off to the lock position.
2. Disconnect the Transmission Simulator 8333A.
3. Disconnect the PCM harness connectors.
4. Measure the resistance between the (T140) MS Solenoid Control circuit and all other circuits in the Transmission Solenoid/TRS Assembly harness connector.
  Is the resistance below 5.0 Ohms between the (T140) MS Solenoid Control circuit and any other circuit(s) in the Transmission Solenoid/TRS Assembly harness connector?
  
  Yes
  - Repair the (T140) MS Solenoid Control circuit for a short to another circuit(s).
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to 6
CHECK THE (T140) MS SOLENOID CONTROL CIRCUIT FOR AN OPEN

1. Connect the PCM Pinout Box 8815 to the PCM C4 harness connector.
  CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install the PCM Pinout Box 8815 to perform diagnosis.
2. Measure the resistance of the (T140) MS Solenoid Control circuit from the Transmission Solenoid/TRS Assembly harness connector to the appropriate terminal of the PCM Pinout Box 8815.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T140) MS Solenoid Control circuit for an open.
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to 7
CHECK THE (T140) MS SOLENOID CONTROL CIRCUIT FOR A SHORT TO GROUND

Courtesy of CHRYSLER LLC
1. Measure the resistance between ground and the (T140) MS Solenoid Control circuit.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the (T140) MS Solenoid Control circuit for a short to ground.
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  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. If no problems are found, replace and program the PCM in accordance with the appropriate service information. With the scan tool, perform Quick Learn.
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
