Safety Information

WARNINGS:

TO AVOID ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY, THE BACKUP POWER SUPPLY MUST BE DEPLETED BEFORE REPAIRING OR REPLACING ANY AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) COMPONENTS. TO DEPLETE THE BACKUP POWER SUPPLY ENERGY, DISCONNECT THE BATTERY GROUND CABLE AND WAIT ONE MINUTE.

FAILURE TO FOLLOW THIS INSTRUCTION MAY RESULT IN PERSONAL INJURY.

Do not use a multimeter to probe the restraints control module. It is possible for the power from the meter battery to trigger the activation of the airbags. Failure to follow this instruction may result in personal injury

NOTES:

It is advisable not to use a cellular phone or to have a cellular phone in close proximity when working on the restraints control module or associated systems

Given the legal implications of a restraints system failure, harness repairs to Air Bag module circuits are not acceptable. Where the text refers to 'REPAIR the circuit', this will normally mean the replacement of a harness

Power Supply Depletion

Before beginning any work on the restraints control module/supplemental restraints system or related components:

1. Remove the ignition key

2. Disconnect the battery leads, ground first

3. Wait 2 minutes for the power circuit to discharge

There are comprehensive instructions on the correct procedures for supplemental restraints system repairs in the manual.

Refer to the relevant section of the workshop manual

Inspection and Verification

CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle

NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests

1. Verify the customer concern

2. Visually inspect for obvious signs of damage and system integrity
