Check SET/ACCEL Switch Operation

Turn ignition off. Disconnect speed control servo/actuator connector C171 (located near right front fenderwell). Using an ohmmeter, check resistance between speed control servo/actuator connector C171 terminals No. 5 and 6 while pressing speed control SET/ACCEL switch. See Figure . If resistance is 612-748 ohms, replace speed control servo/actuator and perform SELF-DIAGNOSTIC TEST. If resistance is not 612-748 ohms, replace speed control switch and perform SELF-DIAGNOSTIC TEST.
