[QUOTE="MacGuyver, post: 456136, member: 18877"] I'm unsure how jscan tests the lights or how the light circuits work. What I mean is there may be a mechanism for just testing the bulb itself that does not verify if the sensor is doing it's job. Same with the cluster self test. Anyone have insight? What method did you use for resetting the ECU? Disconnect positive battery, touch to ground for 30 seconds, replace. Turn key to on, not start, Turn the lights on then off. Turn the key off. Here is a more step by step version.
