Observe these precautions when working on SRS:

When working around steering column and before any repairs are performed, disable SRS. See DISABLING & ACTIVATING AIR BAG SYSTEM .
Always ensure radio is in OFF position before disconnecting battery. This will prevent damage to radio microprocessor.
Before performing any body damage straightening or electrical arc-welding, disable SRS and disconnect front sensors. See DISABLING & ACTIVATING AIR BAG SYSTEM .
Wait about 5 minutes after disabling SRS. SRS control unit maintains SRS voltage for about 5 minutes after system is disabled. Servicing SRS before 5-minute period may cause accidental air bag deployment and possible personal injury.
Always wear safety glasses and gloves when handling a deployed air bag module. Air bag module may contain sodium hydroxide deposits, which is irritating to the skin.
Always use caution when handling any sensors. Never strike or jar sensors. All sensors and mounting bracket bolts must be torqued to specification to ensure proper sensor operation. See TORQUE SPECIFICATIONS table.
Never use any SRS component that has been dropped from 3 feet or higher.
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. No repairs should be performed on any portion of SRS wiring circuit.
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.
Never expose SRS components to temperatures in excess of 212°F (100°C).
Never expose any SRS system components to cleaning agents such as solvents, gasoline, lye, etc.
