Test M: LFC 42, 43 And 44/DTC B2296 - Restraint System - Impact Sensor Fault

PINPOINT TEST M: LFC 42, 43 AND 44/DTC B2296 - RESTRAINT SYSTEM - IMPACT SENSOR FAULT

Normal Operation
The impact sensor(s) provide data to the restraints control module (RCM) for use in calculating impact severity. This is accomplished using various electrical and electro-mechanical sensor(s) throughout the vehicle.

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 DTC B2296 in memory and flash either LFC 42, 43 or 44 depending on the fault (or higher priority code if one exists) on the air bag warning indicator.







This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Impact sensor
- Incorrect sensor mounting
- RCM
