Customer Question

Hey Chris. I have a 2006 Mazda 3 Sport. Have a small electrical issue. Hooked up the battery and as soon as the negative cable touches the battery post, you can hear a pump or motor start running behind the battery box. My guess was the ABS pump. But started pulling fuses and relays until it stopped. The ABS fuses stopped the pump running. I checked for voltage at the fuse terminals. 10A fuse has no power. But both 20A and 30A terminals have 12V at them. Are these getting backed from somewhere?

Welcome I'm Chris aka Moose

Help to understand a little better. Which fuse removed stopped the ABS pump from running: ABS IG 10A, ABS 1 30A, or ABS 2 20A?

The 20 and 30 amp fuses out will still have power at one terminal, since they are powered all the time from within the fuse box. The 10 amp will only have power with the key on. The current information is pointing to a faulty ABS module.

It is the ABS1 30A which kills the constant power issue.

Thanks, ***** ***** removed, to stop the ABS motor constantly running means the ABS module will need to be replaced.
