I wish to clear the ECU error log (I'm trying to trace an ABS sensor fault) - everything I've read says to pull a fuse or disconnect the battery. I've disconnected the battery overnight(!) but it still remembers the faults. If I can't clear the fault history, I can't see what any new faults are as I do things with the sensors. It's a Honda CR-V 1999 model in the UK, with a 2 pin ECU connector, ie pre-OBDII. I have an appropriate reading tool, which gives me the various error codes on the ABS light.
