The restraints control module (RCM) checks all of the impact sensor circuits for faults. If the RCM detects 1 of the following faults on any of the impact sensor circuits, it will store diagnostic trouble code (DTC) B2296 in memory and flash, depending on the fault, either lamp fault code (LFC) 42, 43, 44, 45 or 46 (or higher priority code if 1 exists) on the air bag indicator.
