Check SET/ACCEL Switch Operation
Turn ignition off. Disconnect speed control servo/actuator connector C152 (located on left shock tower). Using an ohmmeter, check resistance between speed control servo/actuator connector C152 terminals No. 5 and 6 while pressing speed control SET/ACCEL switch. See Figure . If resistance is 610-750 ohms, replace speed control servo/actuator and retest system operation. If resistance is not 610-750 ohms, replace speed control switch and retest system operation.
