C0063-54: (VCM) TROUBLESHOOTING DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	PURPOSE: INSPECT VEHICLE CONTROL MODULE (VCM) AND BODY CONTROL MODULE (BCM) FOR MALFUNCTION Switch the ignition off/main power OFF, and then switch it ON (engine off)/(READY off). Perform the DTC inspection for the vehicle control module (VCM) and body control module (BCM). (See DTC INSPECTION .) Is a DTC related to an internal malfunction displayed?	Yes	Repair or replace the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [VCM] .) (See DTC TABLE [BCM] .)
1		No	Go to the next step.
2	PURPOSE: VERIFY SAS CONTROL MODULE AND BODY CONTROL MODULE (BCM) REPLACEMENT RECORD Verify if the SAS control module or body control module (BCM) has been replaced before performing this troubleshooting procedure. Has the SAS control module or body control module (BCM) been replaced?	Yes	After implementing the required servicing when replacing a module again, perform the repair completion verification 1. (Refer to SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA/ISRAEL SPEC.] in service information.) (Refer to BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION in service information.)
2		No	Go to the next step.
3	PURPOSE: SAS CONTROL MODULE FOR MALFUNCTION Perform the DTC inspection for the SAS control module. (See DTC INSPECTION .) Are any DTCs displayed?	Yes	Repair or replace the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [SAS] .)
3		No	Go to the next step.
4	PURPOSE: PERFORM REQUIRED PROCEDURE AGAIN AFTER MODULE REPLACEMENT Perform the procedure required for the body control module (BCM) replacement again according to the BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION . (Refer to BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION in service information.) Perform the VCM initial setting using the M-MDS. (See VCM INITIAL SETTING [CONTROL SYSTEM] .) Switch the ignition off/main power OFF. Clear the DTC recorded in the memory. (See CLEARING DTC .) Perform the DTC inspection for the vehicle control module (VCM). (See DTC INSPECTION .) Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See MALFUNCTION DIAGNOSIS FLOW [CONTROLLER AREA NETWORK (CAN)] .) If the CAN communication is normal, perform the diagnosis from Step 1. If the malfunction recurs, replace the SAS control module and perform the repair completion verification 1. (Refer to SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA/ISRAEL SPEC.] in service information.)
4		No	Perform the repair completion verification 2.
Repair completion verification 1	PURPOSE: VERIFY THAT VEHICLE IS REPAIRED Install/connect the part removed/disconnected during the troubleshooting procedure. Clear the DTC recorded in the memory. (See CLEARING DTC .) Replicate the vehicle conditions at the time the DTC was detected using the following procedure. Implement the repeatability verification procedure. (See REPEATABILITY VERIFICATION PROCEDURE .) Perform the DTC inspection for the vehicle control module (VCM). (See DTC INSPECTION .) Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See MALFUNCTION DIAGNOSIS FLOW [CONTROLLER AREA NETWORK (CAN)] .) If the CAN communication is normal, perform the diagnosis from Step 1. If the malfunction recurs, replace the body control module (BCM), then go to the next step. (Refer to BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION in service information.)
Repair completion verification 1		No	Go to the next step.
Repair completion verification 2	PURPOSE: VERIFY IF OTHER DTCs DISPLAYED Perform the DTC inspection. (See DTC INSPECTION .) Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning location according to the applicable DTC troubleshooting.
