NTC-4: Speed Control Resume/ACCEL Switch

Possible Causes

Turn ignition off. Disconnect RESUME/ACCEL switch. Inspect connectors. Clean or repair as necessary. Connect a jumper wire between S/C switch signal circuit and ground. Turn ignition on. Using scan tool, read S/C switch voltage. If voltage is less than one volt, replace RESUME/ACCEL switch. Perform TEST VER-4A under VERIFICATION TESTS. If voltage is one volt or more, go to next step.
Turn ignition off. Using an ohmmeter, check resistance of RESUME/ACCEL switch ground circuit at RESUME/ACCEL switch connector. If resistance is 5 ohms or more, repair open ground circuit. Perform TEST VER-4A under VERIFICATION TESTS. If resistance is less than 5 ohms, repair open S/C switch signal circuit. Perform TEST VER-4A under VERIFICATION TESTS.
