Observe these precautions when working on SRS:
- When working around steering column and before any repairs are performed, disable SRS. See procedures under DISABLING & ACTIVATING AIR BAG SYSTEM .
- Always ensure radio is off before disconnecting battery. This will prevent damage to radio microprocessor.
- Before straightening damaged metal or arc-welding, disable SRS and disconnect front sensors. See procedures under DISABLING & ACTIVATING AIR BAG SYSTEM .
- After disabling SRS, wait at least 5 minutes before servicing vehicle. SRS control unit maintains SRS voltage for about 5 minutes after system is disabled. Servicing SRS before 5 minutes 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 irritates skin.
- Handle sensors carefully. Never strike or jar sensors. All sensors and mounting bracket bolts must be tightened to specification to ensure proper sensor operation. See TORQUE SPECIFICATIONS .
- Never use any SRS component that has been dropped from 2 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. DO NOT repair any part 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.
- Never expose SRS components to temperatures greater than 167°F (75°C).
- Never expose any SRS system components to cleaning agents such as solvents, gasoline, lye, etc.
