Re: couple a quick ?'s
 

Does the Service LTPWS light come on after a couple miles every time you take the car out?

If so, then one of the tire sensors is bad. It also could be the receiving unit is bad, but thats a small chance.

You can check the codes by jumping pins AB on the ALDL connector and counting the flashes of the light, just like the SES light. But you cant clear codes from the LTPWS light by removing battery power, only by shorting the AB pins 3 times in 10 seconds. Very tricky, but it does work if you're persitent. If there are stored codes, that pesky LTPWS light comes on even when the system is working correctly.

Yes, it comes on after a couple of miles of driving. I've been told though that the sensors can be dangerous if the break free from the clamp, so I will probably get rid of all of them & remove the bulbs....but thank you for the info.
