Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hi there, I am Cam. Attached is the digram. This is the front drivers side of the transmission. You will see the thermostat outlet there and on the top right the filler for the transmission. Your ground wires are below there, 3 of them.
The fuses only stop over amperage of the circuit, but surges can kill it. I would verify none of the connections are bad at the abs module, and if you find no issues there, verify power and ground to the module, as well as the data line. If those are good, then it confirms the module is indeed faulty.
Power and ground you check with the test light, the data line, check that to the data plug purple wire with the key off.
Yes, I suspect you have a ground connection between the body and the engine is bad. I would check that main cable and see.
That where the issue comes, that one I cannot find a good picture. The cable I am thinking about is attached on the passenger side of the underhood area to the body by it. Myself I would check that and even get a jumper cable, attache it to the body and then engine ground and evaluate the issue after that.
