Same thing ! Light pops on at about 30 miles driven. Pull negative terminal to reset. After 30 miles engine won't start after turning off . Thus the reset . Any body around Reno NV that won't charge 100 dollars to code it for me ? ? Tried Auto Zone & Oriellys unfortunately they don't have a clue .

Well it popped up today .

I have a feeling someone is trying to get in my pocket?
It's driving like it's just rolled off the showroom floor . I've tried the reset twice & three times no go it's still there . Any ideas?

Thanks now to see if that's the one my kids play with !

Hello volvo land. Before I pull my front tire can anybody tell me the bolt size for the wheel sensor. Torx socket or MM ?

Remember I took my battery out of it for 3/4 days too
Waiting for used module

Once I noticed it after buying the car !! Like a bone head !! It was shoddy work to say the least .

The original was taken apart and was DIY fix and put back in . The one I put in after # match the first . Are you thinking memory in the original?

We Shall See. I'll post when I get the bad news .

I know the previous owner rewired the rear . It's got to be a short somewhere where the start point is baffles me . Maybe the 4 sensors on the wheels? I think I can do that one at a time being cost prevented for me . Any thoughts on that ?

The module or computer I call it ... under the kick panel and then one in the engine compartment by the radiator over flow .
