After doing my motor mounts everything was fine, till this evening.
When I back up at speed (or even rev the engine in reverse with the brakes applied) the ABS pump comes on and I can feel it in the brake pedal.
Never had that happen before. Didn't know the pump would come on without the brakes being depressed or when the wheels were static.
Gonna check in the morning to see if I knocked something loose. But a quick glance doesn't indicate anything wrong. I may have leaned on the ABS computer connector and need to clean/reattach it. But that's a long shot.
