What C052C means
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.
C052C at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairAfter a drive cycle
Symptoms of C052C
- ABS and ESC warning lamps on
- ABS, traction and stability control switched off
- Code returns only after a short drive
Common causes of C052C
- Most likelyLoose or corroded connector at the ABS unit
- PossibleWorn brushes or open winding in the pump motor
- PossibleMotor relay contact not closing
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 2C | The exact fault in that area. |
What to do next
- Note C052C and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C052C
What does C052C mean?
C052C means "ABS Pump Motor Control Circuit/Open". Open circuit in the ABS pump motor drive: the control unit finds no current path through motor or relay where one should exist. It is a generic code, so it means the same on every make.
Is it safe to drive with C052C?
Drive gently and only to a workshop. With C052C the car can go into limp mode (reduced power) to protect itself.
Will C052C fail an emissions test?
C052C is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C052C to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will C052C clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
