Diagnostic Test

WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

DETERMINE IF RELATED TCM POWER INPUT DTCS ARE PRESENT
1. With the scan tool, read Transmission DTCs
  Are any TCM Power Input DTCs present?
  
  Yes
  - Refer to DIAGNOSIS AND TESTING and perform the appropriate diagnostic procedure.
  No
  - Go To 2
TRANSMISSION SOLENOID/TRS ASSEMBLY
1. Turn the ignition OFF.
2. Remove the Starter Relay from the PDC.
  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 (special tool #8333B, Simulator, Transmission).
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
  - Replace the Transmission Solenoid/TRS Assembly in accordance with the Service Information.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 3
TRANSMISSION SOLENOID/TRS ASSEMBLY
1. With the scan tool, continue to actuate the MS Solenoid for the period of two minutes using the Transmission Simulator.
2. After two minutes of actuation, with the scan tool, stop the actuation and check for transmission DTCs.
  Did DTC P2706 reset during the actuation test?
  
  Yes
  - Go To 4
  No
  - Replace the Transmission Solenoid/TRS Assembly in accordance with the Service Information.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE .
(T140) MS SOLENOID CONTROL CIRCUIT SHORTED TO ANOTHER CIRCUIT
1. Turn the ignition OFF.
2. Disconnect the Transmission Simulator (special tool #8333B, Simulator, Transmission).
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 TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 5
(T140) MS SOLENOID CONTROL CIRCUIT OPEN
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 Miller tool 8815A to perform diagnosis.
1. Measure the resistance of the (T140) MS Solenoid Control circuit between the Transmission Solenoid/TRS Assembly harness connector and the appropriate terminal of the PCM C1 harness connector.
  Is the resistance above 5.0 ohms?
  
  Yes
  - Repair the (T140) MS Solenoid Control circuit for an open.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 6
(T140) MS SOLENOID CONTROL CIRCUIT SHORTED TO GROUND
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 TRANSMISSION VERIFICATION TEST. Refer to 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 Service Information. With the scan tool, perform a Quick Learn.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE .
