- With the scan tool, read ABS DTCs.
Does this DTC reset?
Yes
- Go to step 2
No
- The condition that caused the symptom is currently not present. Inspect the related wiring for a possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires.
- Perform the ABS-INTERMITTENT CONDITION TEST. See DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
- CHECK FOR ANY OF THE FOLLOWING ACTIVE DTCs
- With the scan tool, read all active DTCs from all CAN C Bus modules.NOTE: Check for CAN C hardware electrical, VIN Missing/Mismatch, battery or ignition related DTCs.
Does the scan tool display any active DTCs related to the conditions listed above?
Yes
- Diagnose and repair the DTC(s). Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Diagnosis and Testing .
No
- Go to step 3
- With the scan tool, read all active DTCs from all CAN C Bus modules.
- CHECK IF ECM OR PCM DTCs ARE PRESENT
- With the scan tool, read ECM or PCM DTCs.
Are any DTCs present?
Yes
- Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Diagnosis and Testing for gas engine applications and perform the appropriate diagnostic procedure.
No
- Go to step 4
- With the scan tool, read ECM or PCM DTCs.
- VERIFY CORRECT ECM OR PCM IS INSTALLED IN THE VEHICLE
- With the scan tool, verify that the ECM or PCM part number is correct for the vehicle.
Is the correct ECM or PCM installed in the vehicle?
Yes
- Go to step 5
No
- Replace and program the ECM or PCM in accordance with the Service Information.
- Perform appropriate VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .

- VERIFY ECM OR PCM IS PROGRAMMED WITH CORRECT VIN
- With the scan tool, verify that the ECM or PCM is programmed with the correct VIN.
Is the ECM or PCM programmed with the correct VIN?
Yes
- Go to step 6
No
- Using the scan tool, update the VIN in the ECM/PCM.
- Perform the appropriate VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
- With the scan tool, verify that the ECM or PCM is programmed with the correct VIN.
- CHECK FOR ADDITIONAL COMMUNICATION RELATED DTCs
- With the scan tool, select Network View and select Advanced.
Is there more than one module with active DTCs "Logged Against" the ECM or PCM?
Yes
- Replace/update the ECM or PCM in accordance with the service information.
- Perform the appropriate VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
No
- Using the schematics as a guide, check the Anti-Lock Brake Module pins, terminals, and connectors for corrosion, damage, and terminal push out. Pay particular attention to all Communication circuits. If no problems are found, replace the Anti-Lock Brake Module in accordance with the Service Information.
- Perform the ABS VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
- With the scan tool, select Network View and select Advanced.
