Diagnostic Procedure

Step	Inspection		Action
1	VERIFY REAR BODY CONTROL MODULE (RBCM) DTCs AGAIN • Clear rear body control module (RBCM) DTCs using the M-MDS. (See CLEARING DTC [REAR BODY CONTROL MODULE (RBCM)].) • Perform the DTC inspection for the rear body control module (RBCM) using the M-MDS. (See DTC INSPECTION [REAR BODY CONTROL MODULE (RBCM)].) • Is DTC U2100:00 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 with the As-Built data. (See REAR BODY CONTROL MODULE (RBCM) CONFIGURATION (USING AS-BUILT DATA).) • Clear rear body control module (RBCM) DTCs using the M-MDS. (See CLEARING DTC [REAR BODY CONTROL MODULE (RBCM)].) • Perform the DTC inspection for the rear body control module (RBCM) using the M-MDS. (See DTC INSPECTION [REAR BODY CONTROL MODULE (RBCM)].) • Is DTC U2100:00 displayed?	Yes	Using the M-MDS, re-perform the rear body control module (RBCM) configuration using the As-Built data, 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 rear body control module (RBCM) DTCs using the M-MDS. (See CLEARING DTC [REAR BODY CONTROL MODULE (RBCM)].) • Perform the DTC inspection for the rear body control module (RBCM) using the M-MDS. (See DTC INSPECTION [REAR BODY CONTROL MODULE (RBCM)].) • Is DTC U2100:00 displayed?	Yes	Replace the rear body control module (RBCM), then go to the next step. (See REAR BODY CONTROL MODULE (RBCM) REMOVAL/INSTALLATION.)
3		No	Go to the next step.
4	VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed?	Yes	Repair the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [REAR BODY CONTROL MODULE (RBCM)].)
4		No	DTC troubleshooting completed.
