Diagnostic Procedure

Step	Inspection		Action
1	VERIFY BCM DTCs AGAIN • Clear the DTC for the BCM using the M-MDS. (See CLEARING DTC [BCM].) • Switch the ignition ON (engine off or on) and wait for 3 s or more. • Retrieve the BCM DTCs using the M-MDS. (See DTC INSPECTION [BCM].) • Is the same DTC displayed?	Yes	Go to the next step.
1		No	Go to Step 5.
2	VERIFY SAS CONTROL MODULE DTCs • Retrieve the SAS control module DTCs using the M-MDS. (See DTC INSPECTION [STANDARD DEPLOYMENT CONTROL SYSTEM].) (See DTC INSPECTION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].) • Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [STANDARD DEPLOYMENT CONTROL SYSTEM].) (See DTC TABLE [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)
2		No	Go to the next step.
3	VERIFY IF MALFUNCTIONING LOCATION IS SAS CONTROL MODULE DEPENDING ON REPEATABILITY • Clear the DTC for the BCM using the M-MDS. (See CLEARING DTC [BCM].) • Switch the ignition ON (engine off or on) and wait for 3 s or more. • Retrieve the BCM DTCs using the M-MDS. (See DTC INSPECTION [BCM].) • Is the same DTC displayed?	Yes	Replace the SAS control module, then go to the next step. (See SAS CONTROL MODULE REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM].) (See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)
3		No	Go to Step 5.
4	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Clear the DTC for the BCM using the M-MDS. (See CLEARING DTC [BCM].) • Switch the ignition ON (engine off or on) and wait for 3 s or more. • Retrieve the BCM DTCs using the M-MDS. (See DTC INSPECTION [BCM].) • Is the same DTC displayed?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the BCM. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.) Go to the next step.
4		No	Go to the next step.
5	VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [BCM].)
5		No	DTC troubleshooting completed.
