The front impact severity sensor provides data to the restraints control module (RCM) for use in calculating impact severity. This is accomplished using various electrical and electromechanical sensor(s) throughout the vehicle. Refer to Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) in this article.
The RCM checks all of the impact sensor circuits for faults. If the RCM detects one of the following faults on any of the impact sensor circuits, it will store diagnostic trouble code (DTC) B2296 in memory and flash lamp fault code (LFC) 42 (or higher priority code if one exists) on the air bag indicator.
