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.

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.
  
  NOTE: Check the TIPM for any active CAN C hardware DTCs, perform DTC before proceeding.
  
  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.
(Z901) GROUND CIRCUITS OPEN

1. Turn the ignition off.
2. Disconnect the ABS harness connector.
3. Using a 12-volt test light connected to 12-volts, check both (Z901) ground circuits.
  Does the test light illuminate brightly for each circuit?
  
  Yes
  - Go to Step 3.
  No
  - Repair the (Z901) ground circuits for an open.
  - Perform the ABS VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
(F202) IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN OR SHORTED

1. Turn the ignition on.
2. Using a 12-volt test light connected to ground, check the (F202) Ignition Switch Output (Run-Start) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go to Step 4.
  No
  - Repair the (F202) Ignition Switch Output (Run-Start) circuit for an open or short.
  - Perform the ABS VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
(D65) CAN C BUS (+) CIRCUIT OPEN

1. Turn the ignition off.
2. Disconnect the TIPM C3 harness connector.
3. Measure the resistance of the (D65) CAN C Bus (+) circuit between the TIPM connector and the Antilock Brake Module connector.
  Is resistance below 5.0 ohms?
  
  Yes
  - Go to Step 5.
  No
  - Repair the (D65) CAN C Bus (+) circuit for an open.
  - Perform the ABS VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
(D64) CAN C BUS (-) CIRCUIT OPEN

1. Measure the resistance of the (D64) CAN C Bus (-) circuit between the TIPM connector and the Antilock Brake Module connector.
  Is resistance below 5.0 ohms?
  
  Yes
  - Replace the Antilock Brake Module in accordance with the Service Information.
  - Perform the ABS VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
  No
  - Repair the (D64) CAN C Bus (-) circuit for an open.
  - Perform the ABS VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
