Section 1 (Air Bag Restraint System): Diagnosis: Notes
WARNING: This page is about a different car, the 1995 Toyota Tercel. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Failure to follow air bag service precautions may result in air bag deployment and personal injury. See SERVICE PRECAUTIONS . After component replacement, perform system operational check to ensure proper system operation. See SYSTEM OPERATION CHECK .
WARNING:
Some test procedures involve checking resistance across "spiral cable upper connector" or "passenger-side air bag connector". In each case, "connector" refers to half of the connector that leads to wiring harness, NOT half of the connector that leads to air bag. If resistance is measured across half of connector that leads to air bag, air bag may accidentally deploy.
CAUTION:
Ensure ignition switch is in LOCK position before disconnecting or connecting negative battery cable. If ignition switch is in ACC or ON position when negative battery cable is disconnected or connected, center air bag sensor may be damaged. To prevent damage to connector terminals, DO NOT
probe terminal ends. Instead, backprobe terminals (probe terminal where wire enters harness connector).
NOTE:
Spiral cable "upper" connector is connected to steering wheel pad. Spiral cable "lower" connector is located under steering column.
