Test H: Off Switch Is Inoperative

Turn ignition switch to LOCK position. Disconnect speed control servo/actuator harness connector C177. Speed control servo/actuator is located in engine compartment, behind power steering fluid reservoir. See Figure. Using an ohmmeter, measure resistance between speed control servo/actuator harness connector C177 terminals No. 5 (Red/Yellow wire) and No. 6 (Red/Blue wire), with speed control OFF switch pressed. See Figure. If resistance is less than 5 ohms, replace speed control servo/actuator and retest system operation. See SPEED CONTROL SERVO/ACTUATOR CABLE  under REMOVAL & INSTALLATION. If resistance is 5 ohms or more, replace speed control switches and retest system operation. See SPEED CONTROL SWITCHES  under REMOVAL & INSTALLATION.
