Check SET/ACCEL Switch Operation

Turn ignition off. Disconnect speed control servo/actuator connector C165 (located in right rear of engine compartment). Using an ohmmeter, check resistance between speed control servo/actuator connector C165 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-test diagnostics using NGS tester. If resistance is not 612-748 ohms, replace speed control switch and perform self-test diagnostics using NGS tester.
