DTC C0063:54 (VEHICLE CONTROL MODULE) DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	INSPECT VEHICLE CONTROL MODULE (VCM) AND BODY CONTROL MODULE (BCM) FOR MALFUNCTION Switch the ignition OFF, and then switch it ON (engine off). Perform the DTC inspection for the vehicle control module (VCM) and the body control module (BCM). (See DTC INSPECTION .) Is a DTC related to an internal malfunction displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE: [VEHICLE CONTROL MODULE (US)] .) (See DTC TABLE [BODY CONTROL MODULE (BCM) (US)] .)
1		No	Go to the next step.
2	VERIFY SOPHISTICATED AIRBAG SENSOR (SAS) CONTROL MODULE AND BODY CONTROL MODULE (BCM) REPLACEMENT RECORD Verify if the Sophisticated Airbag Sensor (SAS) control module or body control module (BCM) has been replaced before performing this troubleshooting procedure. Has the Sophisticated Airbag Sensor (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. (See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .) (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION [(US)] .)
2		No	Go to the next step.
3	INSPECT SOPHISTICATED AIRBAG SENSOR (SAS) CONTROL MODULE FOR MALFUNCTION Perform the DTC inspection for the Sophisticated Airbag Sensor (SAS) control module. (See DTC INSPECTION .) Is a DTC displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.)] .)
3		No	Go to the next step.
4	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]. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION [(US)] .) Perform the yaw rate initial setting for the vehicle control module (VCM) using the M-MDS. (See VCM INITIAL SETTING .) Switch the ignition 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	Replace the Sophisticated Airbag Sensor (SAS) control module and perform the repair completion verification. (See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .)
4		No	Go to repair completion verification 2.
Repair completion verification 1	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 .) 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 CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(US)] .) 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. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION [(US)] .)
Repair completion verification 1		No	Go to the next step.
Repair completion verification 2	VERIFY IF OTHER DTCs ARE DISPLAYED Perform the DTC inspection. (See DTC INSPECTION .) Is a DTC displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
