ABS Pump Motor Circuit Range/Performance
The pump motor responds, but its current draw or run time is outside the expected range. The control module suspects mechanical wear or hydraulic blockage.

- Abs pump motor
- Abs hydraulic block
- Abs control module
Common causes
- High likelihood: Pump worn, low delivery
- Medium likelihood: Hydraulic block contaminated with brake fluid debris
- Low likelihood: Sensor element aged beyond calibration window
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
