Warning lights when the engine is up to temperature?
Discussion
Ford Focus Mk3 1.6 diesel 115hp 2012 112k (w/Rear Drums)
I have had an issue the past few weeks with an intermittent ABS/TC/TPMS/Stop-Start/Hill Assist warning on the dash... which after time became more and more permanent.
Codes are for the Rear Left (Passenger) Wheel (C0037)
I've replaced the Hub, Sensors and the underbody wiring extension... none of which worked.
Trying to get an appointment at Ford for a diagnostic session, 3 week wait. It went in, they "found" a corroded plug at the under body extension and replaced it. The car seemed fine for 24 hrs (30 minutes of driving) and then on the motorway the same warnings popped up.
Its back to being very intermittent rather than more constant and I think it now it might have something to do with the engine temperature? It only seems to pop up now after the car has finally reached normal operating temperature. It will come on for a few minutes / miles and then reset itself.
Am I maybe looking at the ABS module itself? Its booked in at Ford, again got to wait 2-3 weeks and its a further investigation so double the cost of a basic diagnostic session.
Any thoughts or ideas are GREATLY appreciated! Thanks in advance!

This is the exact same symptom I had on a Smart car which was caused by the steering angle sensor being out of calibration. If would never cause a problem around town or on twisty A/B roads, but a few miles on a DCW or motorway and I'd get a warning light and no ABS or stability control. This is because the mismatch between the yaw sensor and steering angle is stable and can persist for long enough when driving in a straight line.
Interesting, so going in a straight line, it thinks something is wrong? Gassing Station | Suspension, Brakes & Tyres | Top of Page | What's New | My Stuff
