Two mechanics have now spent a total of 5 hours on my son's car and we are not much further on with the engine problem that I described here 20 February. (It starts OK then cuts out after about 2-3 minutes, then starts instantly, then cuts out again etc.)
Today we were told that the engine coolant temperature sender was not connected due to corroded terminals so the ECU permanently thinks the engine is cold. Bypassing the sensor with a resistor made the engine run smoother but it still cuts out after a couple of minutes. The mechanic suspects that there is an ECU fault.
Can anyone tell me please:
- Where is the Cedric ECU located?
- How does the self-diagnosis system work i.e. what do I have to do to get it to perform a self-test? and
- When I have the readout, how do I interpret it?
As I said a couple of weeks ago, very few Cedrics came to the UK so owner-maintenance manuals are not available. I'd really appreciate any help that you can give me. Thanks.
