CAUTION: The order in which diagnostic trouble codes are diagnosed is very important. Failure to diagnose the diagnostic trouble codes in the order specified may result in extended diagnostic time, incorrect diagnosis and incorrect parts replacement.

The diagnostic procedures used in this section are designed to find and repair air bag system malfunctions.

To get the best results, it is important to use the diagnostic flow tables and follow the sequence in the following.
1. Perform the "Air Bag Diagnostic System Check Flow".
(The "Air Bag Diagnostic System Check Flow" must be the starting point of any air bag system diagnosis.

The "Air Bag Diagnostic System Check Flow" checks for proper "AIR BAG" warning lamp operation through "AIR BAG" warning lamp and whether air bag diagnostic trouble codes exist.)

2. Refer to the proper diagnostic table as directed by the "Air Bag Diagnostic System Check Flow:
(The "Air Bag Diagnostic System Check Flow" will lead you to the correct table to diagnose any air bag system malfunctions. Bypassing these procedures may result in extended diagnostic time, incorrect diagnosis and incorrect parts replacement.)
