As per Taffybhoy's thread in chat, I have had intermittant spanner light for months, and it now seems to be getting worse.
At first I had numerous codes relating to thermostat and misfires but I have slowly got rid of most of them.
But still the spanner light! Only codes left are:
and p1565 which is cruise control servo related; don't think this one is causing spanner as rarely use CC. If anyone knows about this code tho please explain.
I know these codes relate to the radiator fan. I have checked and cleaned the fan ECM, also the two main ECU connectors. My car (z18xe) does not seem to have the silver box connector on the battery box that the diesels have (i read about this and saw pictures in an old thread)
What I want to know is there anything else like wiring or connectors I can check? I am reluctant to replace the fan ECM until I rule everything else out, but spanner light is doing my head in.
