Diagnostic Test

WARNING: This page is about a different car, the 2009 Dodge Caliber. 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: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.
    2. With 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 Figure 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.
  2. (A415) FUSED B(+) CIRCUIT OPEN OR SHORTED

    1. Turn the ignition off.
    2. Disconnect the Intrusion Transceiver Module C1 and C2 harness connectors.
    3. Using a 12-volt test light connected to ground, check the (A415) Fused B(+) circuit.

      Does the test light illuminate brightly?

      Yes 

      • Go to Step  3.

      No 

  3. (Z941) GROUND CIRCUITS OPEN

    1. Using a 12-volt test light connected to 12-volts, check the (Z941) ground circuits.

      Does the test light illuminate brightly for each circuit?

      Yes 

      • Go to Step  4.

      No 

  4. (D55) AND (D54) CAN B BUS CIRCUITS OPEN

    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 

      No
