Handling the air bag module improperly can accidentally deploy the air bag module, which may seriously injury you. Read the air bag system service warnings and cautions before handling the air bag module. (See (See AIR BAG SYSTEM SERVICE WARNINGS [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .) (See AIR BAG SYSTEM SERVICE CAUTIONS [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .)

Disconnect the negative battery terminal and wait for 1 min or more. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)
Remove the driver-side air bag module. (See DRIVER-SIDE AIR BAG MODULE REMOVAL [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .) (See DRIVER-SIDE AIR BAG MODULE INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .)
Disconnect the clock spring connector (part wiring harness-side).

Measure the resistance between clock spring terminals 3E and 3A (part wiring harness-side) using a ohmmeter.
