WARNING:
To avoid deployment when troubleshooting the SRS, DO NOT
use electrical test equipment such as a battery powered or ac-powered voltmeter, ohmmeter, etc., or any type of electrical equipment other than that specified in this article. DO NOT
use a non-powered probe type tester. Instructions in this article must be followed carefully, otherwise personal injury may result.
The diagnostic procedures used in this section are designed to find and repair SRS malfunctions. To get the best results, it is important to use the diagnostic charts and follow the sequence listed below:
- Perform the SRS DIAGNOSTIC SYSTEM CHECK. The SRS DIAGNOSTIC SYSTEM CHECK must be the starting point of any SRS diagnostics. The "SRS Diagnostic System Check" checks for proper "AIR BAG" warning lamp operation, the ability of the DERM to communicate through the "Serial Data" line and whether SRS diagnostic trouble codes exist.
- Refer to the proper diagnostic chart as directed by the SRS DIAGNOSTIC SYSTEM CHECK. The SRS DIAGNOSTIC SYSTEM CHECK will lead you to the correct chart to diagnose any SRS malfunctions. Bypassing these procedures may result in extended diagnostic time, incorrect diagnosis and incorrect parts replacement.
- Repeat the SRS DIAGNOSTIC SYSTEM CHECK after any repair or diagnostic procedures have been performed. Performing the SRS DIAGNOSTIC SYSTEM CHECK after all repair or diagnostic procedures will ensure that the repair has been made correctly and that no other malfunctions exist.
