Diagnostic Test

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

TEST FOR INTERMITTENT CONDITION
NOTE:
If the scan tool is unable to identify the vehicle, a CAN C bus concern may be present. Refer to DIAGNOSIS AND TESTING and perform the CAN C BUS NO RESPONSE diagnostic procedure.

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 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
CHECK THE (A903), (A904), (A905) AND (A906) FUSED B(+) CIRCUITS FOR AN OPEN OR SHORT CIRCUIT

1. Turn the ignition off.
2. Disconnect the BCM B and C harness connectors.
3. Using a 12-volt test light connected to ground, check each Fused B(+) circuit.
  Does the test light illuminate brightly for each circuit?
  
  Yes
  - Go To 3
  No
  - Repair the open or short in the (A903), (A904), (A905) or (A906) Fused B(+) circuit.
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECK THE (Z904) GROUND CIRCUIT FOR AN OPEN

1. Using a 12-volt test light connected to 12-volts, check the (Z904) Ground circuits.
  Does the test light illuminate brightly for each circuit?
  
  Yes
  - Go To 4
  No
  - Repair the open in the (Z904) Ground circuit.
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECK THE (D45) AND (D46) CAN C BUS (+) CIRCUITS FOR AN OPEN

1. Turn the ignition off.
2. Disconnect the Rear CAN C Star Connector C2 harness connector.
3. Measure the resistance of the (D45) CAN C Bus (+) circuit between the Rear CAN C Star Connector C2 harness connector and the BCM E harness connector.
4. Measure the resistance of the (D46) CAN C Bus (-) circuit between the Rear CAN C Star Connector C2 harness connector and the BCM E harness connector.
  Are the resistances below 5.0 Ohms?
  
  Yes
  - Replace the BCM in accordance with the Service Information. Refer to MODULE, BODY CONTROL, REMOVAL .
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Repair the open in the (D45) CAN C Bus (+) or (D46) CAN C Bus (-) circuit.
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
