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.
  1. CHECK IF THE DTC IS CURRENT 
    1. With the scan tool, read DTCs.

      Is the status Active or is the Starts Since Set counter 0 for this DTC?

      Yes 

      • Go To  2

      No 

      • Go To  5
  2. CHECK THE (T16) TRANSMISSION CONTROL OUTPUT 
    1. Turn the ignition OFF.
    2. Disconnect the PCM C2 harness connector.
    3. Ignition ON, Engine Not Running.
    4. Measure the voltage on all of the (T16) Transmission Control Output circuits on the appropriate terminals of the PCM C2 harness connector.

      Is the voltage above 0.5 of a volt on any of the (T16) Transmission Control Output circuits?

      Yes 

      • Go To  3

      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  .
  3. CHECK THE (T16) TRANSMISSION CONTROL OUTPUT CIRCUIT FOR A SHORT TO VOLTAGE 
    1. Turn the ignition OFF.
    2. Disconnect the PDC C3 harness connector.
    3. Disconnect the Transmission Solenoid/TRS Assembly harness connector.
    4. Ignition ON, Engine Not Running.
    5. Measure the voltage at the (T16) Transmission Control Output circuit in the appropriate terminals of the PCM C2 harness connector.

      Is the voltage above 0.5 volts?

      Yes 

      • Repair the (T16) Transmission Control Output circuit for a short to voltage.
      • Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE  .

      No 

      • Go To  4
  4. CHECK THE (T15) TRANSMISSION CONTROL CIRCUIT FOR A SHORT TO VOLTAGE 
    1. Ignition ON, Engine Not Running.
    2. Measure the voltage of the (T15) Transmission Control circuit.

      Is the voltage above 0.5 volts?

      Yes 

      • Repair the (T15) Transmission Control circuit for a short to voltage.
      • Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE  .

      No 

      • Using the schematics as a guide, check the Power Distribution Center (PDC) terminals for corrosion, damage or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace the PDC in accordance with the Service Information.
      • Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE  .
  5. CHECK 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 set.

      Where any problems found?

      Yes 

      • Repair as necessary.
      • Perform the TRANSMISSION VERIFICATION TEST. Refer to STANDARD PROCEDURE  .

      No 

      • Test Complete.
