SET Button Check (Response Code 1-3-1)
- Turn ignition on. Slide cruise control selector switch to ON position. Using a voltmeter, measure voltage between control unit terminal No. 6 and ground. See Figure . Slide cruise control switch to RESUME position. Voltmeter should indicate battery voltage. With switch in other positions, voltmeter should indicate zero voltage.
- If voltage is not as indicated, check wiring and connectors for open or short circuit. If voltage is as indicated, go to SELECTOR CHECK. If selector checks okay, repeat SYSTEM COMPONENT CHECK. If no response code is generated during SYSTEM COMPONENT CHECK, go to CONTROL UNIT CHECK.
