well the harness didnt get here until yesterday,but I spoke to the mechanic and he was saying the right front hub signal fades after you drive it for a few minutes..hopefully this harness fixes it..more to follow
Well just got the car and they feel the module is bad. They cleaned all the ground areas up but it's still failing.
They gave me a number off of it and it is:
3621 7317-469 052 0
Is that what I'm looking for?
Thanks
mace
Sorry..I have been busy getting our house together to sell and have left this alone. I will hopefully get back to it tomorrow.
Tell you about the results very soon
Thanks to all

I forgot to add but forgot to the coded doesn't pop until about 35-40 miles an hour
Does that have any bearing.
Also I'me getting tpms errors so could that be the problem?
well..i worked with my mechanic we checked connections and ohmed some areas , everything looked good.
He put his scanner on the car and most times it had trouble talking to module ..grrrr
I know you had a new hub installed, but there is a test mentioned in the service manual to test it with a DMM and spinning the wheel. Might check that to be sure the hub is ok. Looks like it is intermittent. And the c1233 says there is an open/short in there somewhere. Sounds more like a hub issue or wiring. Check the wiring to that wheel from the hub to the connector on the EBCM. Info below shows which wires in the graphic. ABS wiring at the bottom of the page shows the connector to the EBCM. You can do the same test on pins 14 and 30 there to see how far upstream the problem is when spinning the wheel. If it works fine at the connector to the EBCM then the module could be the problem, otherwise, you can better follow the problem down to the wheel hub. These GIF images are tough to read so I added the PDF files as well.
