Hello!

I've got a problem with my wheel speed sensors and I need to troubleshoot the ABS wiring harness. Does anybody have the wiring diagram or pin assignment schematic for a 1992 Cadillac Seville STS EBCM? It's a Bosch system. I think the Bosch ABS schematic is the same for all Cadillac Seville/Eldorados from 1991-1993 w/o traction control.

Thanks

Most often such things are simply a connector pulled of a wheel speed senor, or a disconnected wheel height sensor. The wheel speed sensors are in the center of the hub in each wheel. What are the OBD codes? Check the link in my signature block for how to read the OBD codes.

I pulled the codes yesterday, got code 25 - LF wheel speed sensor fault. I wanted the wiring schematic so that I could troubleshoot the wiring all the way from the module to the sensors, to be able to rule out any bad or broken wires. The wheel speed sensors are integrated with the wheel hub and they go for about $120 each. Just want to make sure I don't buy anything I don't need.

You probably don't need a hub or sensor. It's common to knock the connector off when getting the car serviced.
