c1235

Hi, first timer! Thanks everyone for the many times I've used what I have read here to help solve my problems. Here's my first post. C1235 fault code. Have recently changed the EBCM (second hand) for other reasons including the C1235 and I've installed a new RR wheel bearing and speed sensor. RR is passenger rear wheel? Checked the wire plug to make sure there is good contact. Can I check the input wires for voltage/resistance?

What are you working on?

Sorry, 2002 Cadillac Seville STS.

Normal range for the abs sensor is about 1050 ohms. A scan with abs function scanner can look at wheel speed sensor inputs, this is a comparative test to confirm the input matches other wheel speeds.
