C053BABS Valves Supply Voltage Circuit/Open
- Generic OBD-II code · Chassis
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- 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.
