This DTC sets if the SECM receives invalid data from the RCM. Using a diagnostic scan tool, RETRIEVE and DIAGNOSE all RCM DTCs. REFER to appropriate Supplemental Restraint System (SRS) article. If the diagnostic scan tool cannot communicate with the RCM, REFER to appropriate Module Communications Network article. If no DTCs are set in the RCM, the concern may be intermittent. SET the ignition to OFF and WAIT one minute. DISCONNECT and INSPECT all RCM electrical connectors and related in-line connectors for corrosion, bent pins, pushed-out pins and spread terminals. REPAIR as necessary.
