Speed Control Resume/ACCEL Switch: Cherokee
- Turn ignition on. Turn Speed Control (S/C) ON/OFF switch on. While observing scan tool, press RESUME/ACCEL switch several times. If scan tool displays RESUME/ACCEL switch PRESSED and RELEASED, test is compete. If scan tool does not display PRESSED and RELEASED, go to next step.
- Turn ignition off. Disconnect S/C RESUME/ACCEL switch. See SPEED CONTROL SWITCHES under REMOVAL & INSTALLATION. Inspect connector. Clean or repair as necessary. Connect a jumper wire between S/C RESUME/ACCEL switch connector terminal No. 2 (Red/Light Green wire) 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 between RESUME/ACCEL switch harness connector terminal No. 1 (Brown/Yellow wire) and ground. 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.
