Diagnostic Test
1.VERIFY DTC IS ACTIVEDoes this DTC reset?
Yes
- Go To 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.
- Refer to the ABS-INTERMITTENT CONDITION TEST. (Refer to 5 - BRAKES - DIAGNOSIS AND TESTING)
2.CHECK FOR ANY OF THE FOLLOWING ACTIVE DTCs
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 the Table of Contents in the applicable Section.
No
- Go To 3
3.CHECK IF TIPM DTCs ARE PRESENT
Are any DTCs present?
Yes
- Diagnose and repair the DTC(s). Refer to the Table of Contents in the applicable Section.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
- Go To 4
4.VERIFY TIPM IS CONFIGURED CORRECTLY
Is the correct TIPM installed in the vehicle?
No
- Replace and program the TIPM in accordance with the Service Information.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
Yes
- Go To 5
5.CHECK IF ECM OR PCM DTCs ARE PRESENT
Are any DTCs present?
Yes
- Diagnose and repair the DTC(s). Refer to 9 - ENGINE - DIAGNOSIS AND TESTING.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
- Go To 6
6.VERIFY CORRECT ECM OR PCM IS INSTALLED IN THE VEHICLE
Is the correct ECM or PCM installed in the vehicle?
Yes
- Replace and program the ECM or PCM in accordance with the Service Information.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
- Go To 7
7.VERIFY ECM OR PCM IS PROGRAMMED WITH CORRECT VIN
Is the ECM or PCM programmed with the correct VIN?
Yes
- Using the scan tool, perform PCM Replaced to update the VIN in the PCM.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
- Go To 8
8.CHECK FOR ADDITIONAL COMMUNICATION RELATED DTCs
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 POWERTRAIN VERIFICATION TEST. Refer to 9 - ENGINE - DIAGNOSIS AND TESTING.
No
- Using the schematics as a guide, check the Anti-Lock Brakes 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 Brakes Module in accordance with the Service Information.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
