Service Precautions

Observe these precautions when working with air bag systems:

• Always disable SRS before performing any air bag repairs. See DISABLING & ACTIVATING AIR BAG SYSTEM .
• Always ensure radio is off before disconnecting battery. This will prevent damage to radio microprocessor.
• Always wear safety glasses and gloves when handling a deployed air bag module and/or seat belt tensioners. Air bag module and/or seat belt tensioners may contain sodium hydroxide deposits, which irritate skin.
• Use caution when handling sensors. Never strike or jar sensors. All sensors and mounting bracket bolts must be tightened carefully to ensure proper sensor operation.
• Never apply power to SRS if any SRS crash sensor is not securely mounted to vehicle.
• Never make any measurement directly on air bag module(s) or seat belt tensioners. A fault in these components is determined by a process of elimination using Special Test Resistor (998 8695).
• To avoid accidental 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. when air bag module(s) or seat belt tensioners are connected to SRS.
• When called for during diagnostics, use a DVOM with ohmmeter ranges of 2000 ohms and 200,000 ohms with a one-percent error tolerance.
• Wiring repairs should not be performed on any portion of SRS wiring harness.
• Always handle air bag modules with trim cover away from your body. Always place air bag module on workbench with trim cover facing up, away from loose objects.
