Test F: Set/ACCEL 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. 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 SET/ACCEL switch pressed. See Figure. If resistance is 646-714 ohms, replace speed control servo/actuator. See SPEED CONTROL SERVO/ACTUATOR CABLE  under REMOVAL & INSTALLATION. If resistance is not 646-714 ohms, replace speed control switch and retest system operation. See SPEED CONTROL SWITCHES  under REMOVAL & INSTALLATION.
