Air Bag Diagnostic System Check

WARNING: Use of any type of electrical test equipment other than test equipment specified in this manual for performing diagnosis on the air bag/pretensioner systems, including use of a battery-powered or AC-powered voltmeter or ohmmeter or a non-powered probe-type tester, can cause the air bag module or seat belt pretensioner to be activated, possibly causing personal injury. Never use any electrical test equipment other than test equipment specified in this manual and be sure to carefully follow the instructions provided.

CAUTION: Failure to use proper air bag diagnostic and repair procedures can result in extended diagnostic time, false diagnosis results, parts damage, or inappropriate parts replacement.

Be sure to diagnose DTCs in the order specified.
Be sure to use the correct terminal adapter from the connector test adapter kit (special tool) for resistance or voltage measurement.
Do not try to repair a faulty air bag wire harness if you find an open circuit, defective connector, or damaged terminal. Replace the wire harness as an assembly.

NOTE: When a check for proper connection is required, refer to INSPECTION OF INTERMITTENT AND POOR CONNECTIONS: EXCEPT ADVANCED AIR BAG .
