C1251Pump motor circuit open
- Toyota/Lexus code · ABS / stability control
- Lights a warning lamp
- How the car detects it
- The electric pump motor in the brake actuator (or in the brake booster pump, on cars with a hydraulic booster) has an open circuit. While this fault is stored, the skid control unit may switch off VSC (stability control) and traction control, and sometimes ABS; normal braking still works. Drive gently and have it checked.
- What you may notice
