Test K: LFC 42/DTC B2296 - Restraint System - Impact Sensor Fault

PINPOINT TEST K: LFC 42/DTC B2296 - RESTRAINT SYSTEM - IMPACT SENSOR FAULT

Normal Operation
The restraints control module (RCM) monitors all of the impact sensor circuits for faults. If the RCM detects a low resistance, open circuit, a short to ground or a short to voltage on any of the impact sensor circuits, it will store DTC B2296 in memory and send a message to the instrument cluster (IC) module to flash LFC 42 (or higher priority code if one exists) on the air bag warning indicator.
