Possible Causes

A RCM configuration fault can be caused by a RCM configured incorrectly, incorrect RCM installed in vehicle, incorrect seat assembly installed in vehicle or incorrect seat component installed in vehicle.

1. Perform on-demand self-test
   
   Turn ignition switch to OFF position. Connect scan tool to Data Link Connector (DLC). See USING SCAN TOOL  under DIAGNOSTICS. Turn ignition switch to RUN position. Retrieve and record any continuous Diagnostic Trouble Codes (DTCs). See RETRIEVING FAULT CODES  under DIAGNOSTICS. Perform on-demand self-test. See ON-DEMAND SELF-TEST  under DIAGNOSTICS. If DTC B2477 was retrieved during on-demand self-test, go to next step. If DTC B2477 was not retrieved during on-demand self-test, DTC B2477 is continuous fault. Perform RCM configuration. See RESTRAINTS CONTROL MODULE (RCM) CONFIGURATION  under DIAGNOSTICS.
2. Check vehicle for correct part content
   
   Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Check part numbers of RCM, right front seat cushion and right and left front seat backs against numbers listed in master parts catalog. If part numbers match part numbers listed in master parts catalog, go to next step. If part numbers DO NOT match part numbers listed in master parts catalog, replace incorrect parts as necessary. Activate air bag system. See ACTIVATING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Clear all DTCs. See CLEARING FAULT CODES  under DIAGNOSTICS.
3. Check RCM module
   
   Perform RCM configuration. Perform on-demand self-test. If DTC B2477 was retrieved during on-demand self-test, replace RCM. See RESTRAINTS CONTROL MODULE (RCM)  under REMOVAL & INSTALLATION. Activate air bag system. Clear all DTCs. If DTC B2477 was not retrieved during on-demand self-test, fault is corrected. Activate air bag system. Clear all DTCs.
