Cruise Control Indicator Light Circuit
- Turn ignition on. Measure voltage (backprobe) between ground and terminal No. 4 (Yellow/Black wire) of cruise control ECU. Battery voltage should be present with cruise control switch in OFF position. Voltage should be less than 1.2 volts with cruise control switch in ON position.
- 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.
