Diagnostic Test
1. VERIFY DTC IS ACTIVENOTE: This DTC must be active for the results of this test to be valid. If DTC C2206-VEHICLE CONFIGURATION MISMATCH is present it must be repaired before continuing.
Turn the ignition on.
With the scan tool, read and record ABS DTCs.
With the scan tool, read and record Environmental Data (EV Data).
With the scan tool, erase ABS DTCs.
Cycle the ignition switch.
With the scan tool, read ABS DTCs.
Does 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
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 the Table of Contents in the applicable Section.
No
- Go To 3
3. CHECK IF FDCM DTCS ARE PRESENT
With the scan tool, read FDCM DTCs.
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 CORRECT FCM CONFIGURATION
With the scan tool, verify that the FCM part number is correct for the vehicle and programmed correctly.
Is the correct FCM installed in the vehicle?
No
- Replace and program the FCM 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
With the scan tool, read ECM or PCM DTCs.
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
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?
No
- Replace and program the ECM or PCM in accordance with the Service Information.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
Yes
- Go To 7
7. 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?
No
- Using the scan tool, perform PCM Replaced to update the VIN in the PCM.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
Yes
- Go To 8
8. 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 POWERTRAIN VERIFICATION TEST. Refer to 9 - ENGINE - DIAGNOSIS AND TESTING.
- Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
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).
