Yes

Diagnose and repair the DTC(s). Refer to the Table of Contents in the applicable Section.

Go To 3

3.CHECK IF FDCM 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).

Go To 4

4.VERIFY CORRECT FCM CONFIGURATION

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

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).

Go To 6

6.VERIFY CORRECT ECM OR PCM IS INSTALLED IN THE VEHICLE

Yes

Go To 7

7.VERIFY ECM OR PCM IS PROGRAMMED WITH 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

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).

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).
