TroubleLight - Failure Spoiler Control
Hello,
Periodically I get this light to come one and then it goes off somehow. Does anyone know why this is happening? I'm going check the connections when I find the sensor. Is this a known problem? The image has the trouble light symbol. Maybe this isn't a problem?

It is supposed to go on when the car first starts up, it then goes off after you start driving. (about 5MPH)
Otherwise, there is a fault - it is usually in the control module. You need a PST-2 or better to diagnose. AFJ

Wow! You're really an asset to this website!! Thank You!
Thinking about it, I think it only does come on when I first start the car (thats when I noticed it)...then it disappears after driving for a while. I'm going to double check that. Is there a workflow chart somewhere that shows at startup, what are all the checks and diagnostic steps that get executed?

Short answer is, everything gets checked at startup, hence all of the warning lights (notice ABS\ABD takes a second or two to turn off as well).
The Oxygen sensing system does a basic check at startup (Yes, I see oxygen sensors), but it takes up to 5 minutes to finish the sull systems check. The spoiler control logic just needs to "see" the car moving before it can signal "all systems OK"
