Test E: Set/ACCL Switch Is Inoperative

Turn ignition switch to LOCK position. Disconnect speed control servo/actuator harness connector C833. Measure resistance between terminals No. 5 (White wire) and No. 6 (Black wire) at speed control servo/actuator harness connector C833 while pressing speed control SET/ACCL switch. See Figure . If resistance is 646-714 ohms, replace speed control servo/actuator. If resistance is not 646-714 ohms, replace speed control/horn switch.
