What C053B means
Supply fault on the ABS solenoid valves: the feed that powers the inlet and outlet valves, usually switched through a valve relay inside the brake unit, is missing or open. On the 2023 Mitsubishi Outlander PHEV the code is C1048-11 (valve relay), shown as C053B; it is checked with normal supply, set within 2 s, and lights ASC, ABS, brake and check-engine lamps after one trip. A confirmation run needs only ignition on and a 10 s wait. The valve side is fed from a 50 A fusible link and should read 10–16 V at the connector. The fail-safe suspends ABS, EBD, ESC and traction control together with brake assist and the electric parking brake. Without valve power the module cannot modulate pressure, while the foundation brakes keep working.
C053B at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyHard
- Typical labor0.3 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C053B
- ABS, ESC and brake warning lamps on
- ABS, stability control and electric parking brake functions unavailable
Common causes of C053B
- Most likelyValve relay inside the ABS unit faulty
- PossibleFusible link of the valve supply blown
- PossibleDamaged or loose terminal in the ABS connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C053B 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 C053B
What does C053B mean?
C053B means "ABS Valves Supply Voltage Circuit/Open". Supply fault on the ABS solenoid valves: the feed that powers the inlet and outlet valves, usually switched through a valve relay inside the brake unit, is missing or open. It is a generic code, so it means the same on every make.
Is it safe to drive with C053B?
Drive gently and only to a workshop. With C053B the car can go into limp mode (reduced power) to protect itself.
Will C053B fail an emissions test?
C053B 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 C053B to fix?
Difficulty: hard. A typical repair takes 0.3 to 4 hours of work. This is a job for a workshop.
Will C053B clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
