Diagnostic Procedure

Step	Inspection		Action
1	VERIFY REAR BODY CONTROL MODULE (RBCM) DTCs AGAIN • Clear the DTC for the rear body control module (RBCM) using the M-MDS. (See CLEARING DTC [REAR BODY CONTROL MODULE (RBCM)].) • Retrieve the rear body control module (RBCM) DTCs using the M-MDS. (See DTC INSPECTION [REAR BODY CONTROL MODULE (RBCM)].) • Is the same DTC displayed?	Yes	Go to the next step.
1		No	Go to Step 4.
2	PERFORM REAR BODY CONTROL MODULE (RBCM) CONFIGURATION (USING AS-BUILT DATA) • Using the M-MDS, perform the rear body control module (RBCM) configuration (using As-Built data). (See REAR BODY CONTROL MODULE (RBCM) CONFIGURATION (USING AS-BUILT DATA).) • Clear the DTC for the rear body control module (RBCM) using the M-MDS. (See CLEARING DTC [REAR BODY CONTROL MODULE (RBCM)].) • Retrieve the rear body control module (RBCM) DTCs using the M-MDS. (See DTC INSPECTION [REAR BODY CONTROL MODULE (RBCM)].) • Is the same DTC displayed?	Yes	Using the M-MDS, perform the rear body control module (RBCM) configuration (using As-Built data) again, then go to the next step. (See REAR BODY CONTROL MODULE (RBCM) CONFIGURATION (USING AS-BUILT DATA).)
2		No	Go to Step 4.
3	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Clear the DTC for the rear body control module (RBCM) using the M-MDS. (See CLEARING DTC [REAR BODY CONTROL MODULE (RBCM)].) • Retrieve the rear body control module (RBCM) DTCs using the M-MDS. (See DTC INSPECTION [REAR BODY CONTROL MODULE (RBCM)].) • Is the same DTC displayed?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the rear body control module (RBCM). (See REAR BODY CONTROL MODULE (RBCM) REMOVAL/INSTALLATION.) Go to the next step.
3		No	Go to the next step.
4	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 [REAR BODY CONTROL MODULE (RBCM)].)
4		No	DTC troubleshooting completed.
