BTW the sequence to reset the ECU from the drivers seat is (where each number is a one second verbal count i.e. "one-Mississippi, "two-Mississippi" or the UK version "one thousand, two-thousand" etc): -

Press START to Acc mode

count 1 second - Press START to ignition on (foot OFF the brake)

count 3 seconds - Fully depress and release the accelerator pedal five time in quick secession (under 5 seconds)

count 7 seconds - Fully depress and hold accelerator for 10 seconds

release and count 10 seconds

depress and hold 10 seconds

Release, count one second and press START to turn ignition off.
As long as this has been done to within time tolerances the ECU will reset (well mine did). There was no visible notification of success. The car started and I was now able to connect via ODB port. This is a 'harder' reset than disconnecting the battery.

This could be tested by forcing the ECU to throw an error - e.g. disconnect the MAF and start the car.
