7 years 3 weeks ago - 7 years 3 weeks ago #27009 by Paul6004 Holden Epica/Daewoo Tosca steering angle sensor issue was created by Paul6004 9 Months ago this came in with a fault for the steering angle sensor - code C0460-4B. It has returned with the same fault. It is a 2011 Holden Epica (re-badged Daewoo Tosca). I can't seem to re-calibrate it and called the dealers who advised getting another new sensor under warranty before replacing the ABS module. We did that with no change. I ordered a good(?) used ABS pump and fitted that and immediately got C0460, C0131 "pressure sensor" and C0186 "lateral sensor". All the codes cleared except C0460 "SAS not calibrated'. I tried with several scan tools to calibrate it. Finally the old Launch X431 said it was successful but the code showed again. I connected the oscilloscope to the sensor wiring - it has 6 wires. Ground, Positive 2 X CAN hi and 2 X CAN lo. The wiring diagram shows that it shares CAN wiring with the lateral sensor. L8B14F02.png The poitive and ground are good - when I clear the code the positive falls away for a second - maybe that's normal but it doesn't fall away with the engine running. The CAN wiring seems to have some spikes on it - I'm not sure though whether that is a problem or not? Interested in suggestions. pastedImage.png pastedImage1.png Attachments:
