I just bought from Auction, a 1999 F150 for my son. It runs fine and is in great shape. I want the ABS working. This looks like a job we can do together.
TheABS light is lite. I plugged in my OBD2 analyzer and read off the following codes. We looked up the codes. Is there this many individual problems?
Several are related to the rear speed sensor on the rear differential, so we replace that, it was cheap and easy to get to. NO CHANGE, same codes displayed.
We looked up the the ABS control Module, but we don't get an error on it, C1225
What is the best way to troubleshoot this?
C1145 RT Front
C1230 Speed Wheel Sensor Read Input circuit Failure
C1234 Rt Front Wheel Speed Sensor Input signal missing
C1237 Speed Rear Input Signal Missing
C1148 Speed Wheel Sensor RF Coherency Fault
C1229 Speed Wheel Sensor Rear sensor Coherency Fault
C1226 Lamp Brake Warning Output Short to groud
have the same problem?
