2013 Dodge and Ram Dart GTSECTION Diagnostic Test
  1. TEST FOR INTERMITTENT CONDITION 
    NOTE:

    Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.

    1. Turn the ignition on.
      NOTE:

      Make sure the battery voltage is between 10.0 and 16.0 volts.

    2. With the scan tool, read the module status.
      NOTE:

      Check the BCM for any active CAN hardware DTCs, perform DTC before proceeding. Refer to BODY CONTROL MODULE (BCM) - DIAGNOSTIC CODE INDEX .

      Does the scan tool indicate that the module is active on the bus?

      Yes 

      • The no response condition is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring for chafed, pierced, pinched, and partially broken wires and the wiring harness connectors for broken, bent, pushed out, and corroded terminals.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To  2

    1. Turn the ignition off.
    2. Disconnect the Park Assist Module C1 harness connector.
    3. Turn the ignition on.
    4. Using a 12-volt test light connected to ground, check the (F923) Fused Run Relay Output circuit.

      Does the test light illuminate brightly?

      Yes 

      • Go To  3

      No 

      • Repair the open or short in the (F923) Fused Run Relay Output circuit.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  3. CHECK THE (Z924) GROUND CIRCUIT FOR AN OPEN 
    1. Turn the ignition off.
    2. Using a 12-volt test light connected to 12-volts, check the (Z924) Ground circuit.

      Does the test light illuminate brightly?

      Yes 

      • Go To  4

      No 

      • Repair the open in the (Z924) Ground circuit.

  4. CHECK THE (D77) AND (D78) CAN IHS BUS CIRCUITS FOR AN OPEN 
    1. Disconnect the CAN C Body C3 Star Connector.
    2. Measure the resistance of the (D78) CAN IHS Bus (-) circuit between the CAN C Body C3 Star Connector and the Park Assist Module C1 harness connector.
    3. Measure the resistance of the (D77) CAN IHS Bus (+) circuit between the CAN C Body C3 Star Connector and the Park Assist Module C1 harness connector.

      Are the resistances below 5.0 Ohms?

      Yes 

      No 

      • Repair the open in the (D77) or (D78) CAN IHS Bus circuit.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
