C052CABS Pump Motor Control Circuit/Open
- Generic OBD-II code · Chassis
- Turns on the check-engine light
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- Open circuit in the ABS pump motor drive: the control unit finds no current path through motor or relay where one should exist. Mitsubishi lists C1051-13 as C052C on the 2023 Outlander PHEV within the same frame as C052B (normal supply, up to 12 s, ABS, ASC, brake and engine lamps after one trip, stability and regenerative braking functions off). Its confirmation drive runs at roughly 50 km/h for about two minutes, so a cleared code may only return on the road. A Bosch patent spots an interruption while the motor is not driven: two resistors bias both terminals to a middle level, and a broken loop drags one terminal down and the other up. Likely causes are a loose connector, burnt brushes or an open winding inside the hydraulic unit.
