To avoid air bag deployment when trouble shooting SRS, DO NOT use self-powered electrical test equipment such as battery -powered or AC-powered voltmeter, ohmmeter, etc. DO NOT repair any portion of SRS wiring harness.
Always handle air bag module with trim cover away from your body. Always place air bag module on workbench with trim cover up, away from loose objects.
DO NOT expose any SRS component to temperatures in excess of 212°F (100°C).
DO NOT expose any SRS component to cleaning agents such as solvents, gasoline, lye, etc.
