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. 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.

      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 diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To Step  2
  2. CHECK THE (A943) FUSED B(+) CIRCUIT FOR AN OPEN OR SHORT

    1. Turn the ignition off.
    2. Disconnect the Tire Pressure Module harness connector.
    3. Using a 12-volt test light connected to ground, check the (A943) Fused B(+) circuit.

      Does the test light illuminate brightly?

      Yes 

      • Go To Step  3

      No 

      • Repair the open or short in the (A943) Fused B(+) circuit.
      • Perform the TPM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  3. CHECK THE (Z911) GROUND CIRCUIT FOR AN OPEN

    1. Using a 12-volt test light connected to 12 volts check the (Z911) Ground circuit.

      Does the test light illuminate brightly?

      Yes 

      • Go To Step  4

      No 

      • Repair the open in the (Z911) Ground circuit.
      • Perform the TPM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  4. CHECK THE (D93) AND (D94) CAN C BUS CIRCUITS FOR AN OPEN

    1. Disconnect the Rear CAN C Star Connector C3 harness connector.
    2. Measure the resistance of the (D93) CAN C Bus (+) circuit between the Rear CAN C Star Connector C3 harness connector and the Tire Pressure Module harness connector.
    3. Measure the resistance of the (D94) CAN C Bus (-) circuit between the Rear CAN C Star Connector C3 harness connector and the Tire Pressure Module harness connector.

      Are the resistances below 5.0 Ohms?

      Yes 

      No 

      • Repair the open in the (D93) CAN C Bus (+) or (D94) CAN C Bus (-) circuit.
      • Perform the TPM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
