For a complete wiring diagram Refer to Section 8WWhen Monitored:Once per ignition cycle, but not during cranking.Or, if low supply voltage faults are detected.Set Condition:If the Anti-Lock Brakes Module either fails to receive vehicle configuration data from the Engine Control Module (ECM) or Powertrain Control Module (PCM) or Totally Integrated Power Module (TIPM) or the configuration data it receives from the ECM or PCM or TIPM is invalidPossible CausesWIRING HARNESS, TERMINAL, CONNECTOR DAMAGEDTCs RELATED TO BATTERY VOLTAGE, IGNITION, OR VIN MESSAGESCAN C BUS CIRCUITS OPEN OR SHORTEDECM OR PCM DTCs PRESENTECM OR PCM NOT PROGRAMMED OR PROGRAMMED WITH INCORRECT VINTIPM NOT PROGRAMMED OR PROGRAMMED WITH INCORRECT INFORMATIONECM, PCM OR TIPMANTI-LOCK BRAKES MODULE1. VERIFY DTC IS ACTIVEThis 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?YesGo To 2 NoThe 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 DTCsWith the scan tool, read all active DTCs from all CAN C Bus modules.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?YesDiagnose and repair the DTC(s). Refer to the Table of Contents in the applicable Section.NoGo To 33. CHECK IF TIPM DTCs ARE PRESENTWith the scan tool, read TIPM DTCs.Are any DTCs present?YesDiagnose 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). NoGo To 44. VERIFY TIPM IS CONFIGURED CORRECTLYWith the scan tool, verify that the TIPM part number and configuration is correct for the vehicle.Is the correct TIPM installed in the vehicle?NoReplace and program the TIPM in accordance with the Service Information.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE). YesGo To 55. CHECK IF ECM OR PCM DTCs ARE PRESENTWith the scan tool, read ECM or PCM DTCs.Are any DTCs present?YesDiagnose and repair the DTC(s). Refer to 9 - ENGINE - DIAGNOSIS AND TESTING.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE). NoGo To 66. VERIFY CORRECT ECM OR PCM IS INSTALLED IN THE VEHICLEWith 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?NoReplace and program the ECM or PCM in accordance with the Service Information.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE). YesGo To 77. VERIFY ECM OR PCM IS PROGRAMMED WITH CORRECT VINWith 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?NoUsing the scan tool, perform PCM Replaced to update the VIN in the PCM.Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).YesGo To 88. CHECK FOR ADDITIONAL COMMUNICATION RELATED DTCsWith the scan tool, select Network View and select Advanced.Is there more than one module with active DTCs “Logged Against” the ECM or PCM?YesReplace/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).NoUsing 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).
