Diagnostic Test

WARNING: This page is about a different car, the 2011 RAM Pickup. However, it is still accessible from the selected car via links, so may be relevant.
  1. ACTIVE DTC 
    NOTE:

    Diagnose any Misfire DTCs before continuing.

    1. Start the engine and allow it to reach normal operating temperature.
      WARNING:

      When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.

      NOTE:

      It may be necessary to test drive the vehicle in order for this DTC to set.

    2. With the scan tool, select View DTCs.

      Is the DTC Active at this time?

      Yes 

      • Go To  2.

      No 

  2. CHECKING PCM CONTROL SIDE FOR THE MDS SOLENOID (C140)

    1. Turn the ignition off.
    2. Disconnect the C140 harness connector.
    3. Using a 12-volt test light, jumper from the (Z903) Ground Circuit and the (K451) MDS Solenoid No. 1 Control Circuit in the C140 harness connector (PCM side).
    4. Turn the ignition on.
    5. With the scan tool, actuate the MDS Solenoid No. 1.
      NOTE:

      The test light should be illuminated and bright proportional to the maximum duty cycle allowed by the scan tool. For example, if the scan tool allows 100% actuation, the brightness should be as bright as a direct connection to the battery. If the scan tool allows a maximum 25% actuation, the brightness should be 25% as bright as a direct connection to the battery.

      Does the test light illuminate accordingly during the actuation?

      Yes 

      • Go To  3.

      No 

      • Go To  4.

      Is the resistance within an acceptable range?

      Yes 

      • Go To  7.

      No 

      • Visually and Physically inspect the wiring harness between the C140 connector and the MDS Solenoid connector. Repair as necessary. If OK, replace the MDS Solenoid in accordance with the Service Information.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  4. (Z903) GROUND CIRCUIT OPEN (PCM SIDE)

    1. Turn the ignition off.
    2. Using a 12-volt test light connected to 12-volts, probe the (Z903) Ground circuit in the C140 harness connector (PCM side).

      Does the test light illuminate brightly?

      Yes 

      • Go To  5.

      No 

  5. (K451) MDS SOLENOID NO. 1 CONTROL CIRCUIT SHORTED TO GROUND (PCM SIDE)
