Air Bag Control Module Diagnosis

LFC 24 / DTC B1342 (Step 1 And 2):

Normal Operation
The air bag diagnostic monitor monitors the backup power supply, accelerometer operation and memory. If the diagnostic monitor detects a failure in any of these components, it will store a DTC B1342 in memory and flash a LFC 24 on the air bag indicator.

Possible Causes
An air bag diagnostic monitor internal fault could be caused by:
- the internal accelerometer not operating properly.
- the backup power supply not operating properly.
- an internal module circuit fault detected.
- a microcontroller RAM/ROM/EEPROM failure.
