Cruise Control Indicator Light Circuit
- Turn ignition switch to ON position. Measure voltage by backprobing between cruise control ECU terminal No. 4 (Green/Red wire) and ground. With cruise control switch in OFF position, battery voltage should be present. With cruise control switch in ON position, voltage should be less than 1.2 volts.
- If voltage is as specified, no problem is indicated at this time. Fault may be intermittent. If sent here from SYMPTOM TESTS, perform next test under appropriate symptom. If voltage is not as specified, check instrument cluster. See appropriate INSTRUMENT PANELS article. Repair as necessary. If instrument cluster is okay, replace cruise control ECU and retest system.
