Resistance Inspection

Warning

•  Handling the driver-side air bag module improperly can accidentally operate (deploy) the air bag module, which may seriously injure you. Read the service warnings and cautions before handling the air bag module. (See AIR BAG SYSTEM SERVICE WARNINGS [STANDARD DEPLOYMENT CONTROL SYSTEM].) (See AIR BAG SYSTEM SERVICE CAUTIONS [STANDARD DEPLOYMENT CONTROL SYSTEM].) (See AIR BAG SYSTEM SERVICE WARNINGS [TWO-STEP DEPLOYMENT CONTROL SYSTEM].) (See AIR BAG SYSTEM SERVICE CAUTIONS [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

1.  Switch the ignition off.

2.  Disconnect the negative battery cable and wait for 1 min or more. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

3.  Remove the driver-side air bag module. (See DRIVER-SIDE AIR BAG MODULE REMOVAL [STANDARD DEPLOYMENT CONTROL SYSTEM].) (See DRIVER-SIDE AIR BAG MODULE INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM].)(See DRIVER-SIDE AIR BAG MODULE REMOVAL [TWO-STEP DEPLOYMENT CONTROL SYSTEM].) (See DRIVER-SIDE AIR BAG MODULE INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

4.  Remove the steering wheel. (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION.)

5.  Measure the resistance between cruise control switches E and A under the following conditions:
