Diagnostic Strategies

"Check Connection" means inspect connector for proper seating to mating connector, inspect terminals for good contact and inspect wiring for proper crimping to terminal.

All continuity checking is done with the system deactivated. This means that the driver air bag is disconnected and a jumper wire is installed.

"Disconnect" does not mean removal. A disconnected part is not reconnected until specific reconnect instruction is given.

The following test equipment is used:
- Dwell-Tach-Volt-Ohms Tester Rotunda 059-00010 or equivalent.
- Jumper Wire

NOTE: Attach positive (+) lead to circuit voltage and negative (-) lead to specified ground. (If a Digital Voltmeter is used on Circuit 608 with monitor disconnected, the readout will not indicate the correct voltage).

All resistance checks must be made with the negative lead of the ohmmeter at vehicle ground not battery ground, unless specifically directed otherwise. Three places are recommended; the metal bracket of starter relay, the ignition lock cylinder on the steering column, or a ground wire from harness under instrument panel.
