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. ACTIVE DTC 
    NOTE:

    If this DTC sets intermittently, it is possible that the controller is overheating in extremely hot temperatures. This is considered a normal protection operation. No repair is necessary.

    NOTE:

    Low battery voltage can cause excessive current draw in very hot and cold ambient temperatures. Make sure the battery can pass a load test before continuing. Review Freeze Frame information to determine the ambient temperature when the DTC set.

    NOTE:

    If P2072 is also set, this indicates that the cold weather ice blockage routine has run. No repair action is necessary.

    NOTE:

    Diagnose and repair any Throttle Position sensor, system voltage, or 5-Volt supply DTCs before continuing with this test.

    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.

    2. With the scan tool, select View DTCs.

    1. Turn the ignition off.
    2. Measure the resistance between the (K124) ETC Motor (+) circuit and the (K126) ETC Motor (-) circuit.

      Is the resistance above 10k Ohms?

      Yes 

      • Go To  6

      No 

      • Repair the short to between the (K124) ETC Motor (+) circuit and the (K126) ETC Motor (-) circuit.
