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.
  1. CHECK IF 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  3

      No 

      • Go To  8
  2. CHECK THE (T16) TRANSMISSION CONTROL OUTPUT OPEN OR HIGH RESISTANCE

    1. Turn the ignition off to the lock position.
    2. Disconnect the Transmission Solenoid/TRS Assembly harness connector.
    3. Ignition on, engine not running.
    4. Using a scan tool, actuate the TCM relay.
    5. Using a test light connected to ground, check the (T16) Transmission Control Output circuit.
      NOTE:

      The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

      Does the test light illuminate brightly on the (T16) Transmission Control Output circuit?

      Yes 

      • Go To  3

      No 

  3. CHECK THE (T84) EMCC VFS CONTROL CIRCUIT FOR AN OPEN

    1. Turn the ignition off to the lock position.
    2. Disconnect the PCM C1 harness connector.
    3. Measure the resistance of the (T84) EMCC VFS Control circuit between the Transmission Solenoid/TRS Assembly harness connector and the PCM C1 harness connector.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go To  4

      No 

  4. CHECK THE (T84) EMCC VFS CONTROL CIRCUIT FOR A SHORT TO GROUND 
    Fig 3: Checking EMCC VFS Control Circuit For A Short To Ground

    1. Measure the resistance between ground and the (T84) EMCC VFS Control circuit.

      Is the resistance below 100k Ohms?

      Yes 

      No 

      • Go To  5
  5. CHECK THE (T84) EMCC VFS CONTROL CIRCUIT FOR A SHORT TO VOLTAGE 
    Fig 4: Checking EMCC VFS Control Circuit For A Short To Voltage

    1. Ignition on, engine not running.
    2. Measure the voltage of the (T84) EMCC VFS Control circuit.

      Is the voltage above 0.5 of a volt?

      Yes 

      No 

      • Go To  6
  6. CHECK THE (T84) EMCC VFS CONTROL CIRCUIT FOR A SHORT TO ANOTHER CIRCUIT 
    Fig 5: Checking EMCC VFS Control Circuit For A Short To Another Circuit
    GC0150175Courtesy of CHRYSLER GROUP, LLC
    1. Turn the ignition off to the lock position.
    2. Measure the resistance between the (T84) EMCC VFS Control circuit and all other circuits in the Transmission Solenoid/TRS Assembly harness connector.

      Is the resistance below 100k Ohms between the (T84) EMCC VFS Control circuit and any other circuit in the Transmission Solenoid/TRS Assembly harness connector?

      Yes 

      No 

      • Go To  7
  7. CHECK THE EMCC VFS SOLENOID 
    1. Turn the ignition off to the lock position.
    2. Measure the resistance of the EMCC VFS Solenoid between the (T84) EMCC VFS Control and the (T16) Transmission Control Output on the Transmission Solenoid/TRS Assembly connector.

      Is the resistance of the EMCC VFS SOLENOID 5.0 Ohms (± 0.5 Ohms) at 21° C (70° F)?

      Yes 

      • Using the schematics as a guide, check the Powertrain Control Module (PCM) pins, terminals, and connectors 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. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
      • Perform the 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST  .

      No 

  8. CHECK 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. Check for any Service Bulletins that may apply.

      Were there any problems found?

      Yes 

      No
