Engine running and taken for a drive, while live data running. Still 0 volts displayed, at all times.
No pedal trick, besides don't see how that can give anything above what code reader I have.
Still think it is the ABS pump, as it never says any positive volts, speed sensor data, everything else looks good.
You keep saying you've checked the fuse by looking at ... since when have your eyes been electrically continuous Put a meter on the fuse and check for continuity .. it is the ONLY way to correctly check a fuse ... how do you know the visible bit has not broken off one of the legs in the corner
Might not be that, but for the sake of doing a job PROPERLY... it would rule it out once and for all ... I can see you being very pissed off if a new fuse were to fix the problem .....
Tested with MultiMeter, all good for ABS fuses.
