Never use any SRS component that has been dropped from 3 feet or more.
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 perform any repair on any portion of SRS wiring circuit.
