Diagnostic Test

WARNING: This page is about a different car, the 2013 Dodge Avenger and 2013 Chrysler 200. However, it is still accessible from the selected car via links, so may be relevant.

TEST FOR INTERMITTENT CONDITION
NOTE:
Check for any Technical Service Bulletins (TSBs) 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 IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.
2. Using the scan tool, select ECU View.
  NOTE:
  A red "X" will be next to the module that is not communicating, indicating that the module is not active on the Bus network. A green check indicates that the module is active on the Bus network.
  
  Does the scan tool display a red "X" next to the module?
  
  Yes
  - Go To Step 2
  No
  - 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.

1. Turn the ignition off.
2. Disconnect the WCM harness connector.
3. Using a 12-volt test light connected to ground, check the (A411) Fused B(+) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To Step 3
  No
  - Repair the (A411) Fused B(+) circuit for an open or short.
  - Perform the WCM VERIFICATION TEST. Refer to STANDARD PROCEDURE .

  Does the test light illuminate brightly?
  
  Yes
  - Go To Step 4
  No
  - Repair the (Z910) ground circuit for an open.

1. Turn the ignition on.
2. Using a 12-volt test light connected to ground, check the (F20) Ignition Switch Output (Run-Start) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To Step 5
  No
  - Repair the (F20) Ignition Switch Output (Run-Start) circuit for an open or short.
  - Perform the WCM VERIFICATION TEST. Refer to STANDARD PROCEDURE .

NOTE:
One open circuit will not cause this condition.
1. Measure the voltage between the (D54) CAN B Bus (-) circuit and ground.
2. Measure the voltage between the (D55) CAN B Bus (+) circuit and ground.
  Is there any voltage present on either circuit?
  
  Yes
  - Replace the Wireless Control Module in accordance with the Service Information.
  - Perform the WCM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Repair the (D55) and (D54) CAN B Bus circuits for an open. Inspect the connector for damage.
  - Perform the WCM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
