I took my SLE to my mechanic to have it scanned, and what came up was:

C1214 System Relay Contact for Coil Circuit Open
C1248 EBCM Turn the Red Brake Light On.

Im a pretty fair shade-tree mechanic, but I have no idea where to proceed from here. Can someone tell me exactly what these mean, and maybe the best way to fix them?

Thanks.

The short answer is that the internal system relay for the electronic brake control module (EBCM) is defective. The FSM says that it is a non-serviceable part and the EBCM needs to be replaced. Replacements are outrageously expensive. You may want to send a private message to Harofreak00 to see about a used one.

The C1248 just says that the EBCM turned on the red brake light on the dash due to a fault in the system.

I fixed this exact same problem in my 03 LeSabre. I removed the electronic part of the EBCM through the driver's side inner fender (6 torx screws), popped it open, and resoldered everything that looked suspicious. There was a noticeably bad solder joint on the relay pins where it solders into the board. I sealed everything back up really well, plugged it in, and no code. The other option is to pull it and send it to:

Or he could find one from a junkyard.

From what I've read there needs to be some programming done to make it work with your ECM. I'm not sure if that's true... just what I read on the internet when mine failed. Seems to be a common problem.
