Test E: Set/ACCEL Switch Is Inoperative

Turn ignition off. Disconnect speed control servo/actuator connector C146 (located near master cylinder). While pressing SET/ACCEL switch and rotating steering wheel from stop to stop, check resistance between speed control servo/actuator connector C146 terminals No. 5 (Light Blue/Black wire) and No. 6 (Dark Green/Orange wire). See Figure . If resistance is 612-748 ohms, replace speed control servo/actuator and retest system operation. If resistance is not 612-748 ohms, replace speed control switch and retest system operation.
