Hi matt I have a corolla verso (2005 2.0 diesel) the trc and vsc lights are on. my local garge has checked the error codes twice. After cjecking the codes clear but return a few days later. the code recorded yesterday was C1201 and the garge mentioned heater plugs as well. The garge don't seem to know exactly what the problem is. Any ides. Thanks david
The first time the error appeared (mid April) the codes were c1201 ecu, c0371 yaw rate sensor and p0380 glow plugs.
Thank you for your reply - I think you have explained things clearly and identified what I need to do.
These are the codes and descriptions given to me by my garage:
c0371 yaw rate sensor signal fault
c1201 engine control unit
p0380 glow plugs/heater a malfunction
The garage cleared these and said I should wait and see if any of the warning lights came back on.
After about 3 weeks the lights came on again (the TRC and VSC together with the engine symbol). I took the car back to the garage on 14 April and the only code was c1201 engine control unit, but the garage wrote "plus glow plugs" on the invoice.
They cleared the faults but the warning lights came on again the next day.
A few weeks before the faults first appeared I had a puncture and the tyre shop had to knock the rust of the rear brake disc with a hammer - could this have caused any of the problems?
