C1252 is an OBD-II diagnostic trouble code meaning “Manufacturer-Specific Chassis Code (commonly ABS/Brake Pressure or Wheel Circuit).” C1252 is a chassis code that is largely manufacturer-specific, so the precise definition depends on the vehicle make. It generally points to a fault within the ABS/traction/brake hydraulic control system, such as a pressure sensor, solenoid, or wheel-circuit problem detected by the ABS control module. Because chassis 'C' codes affect braking and stability systems, related warning lights (ABS/traction) often illuminate and the function may be temporarily disabled. The exact component and circuit should be confirmed with make-specific service data. This code is most commonly reported on 2007-2017 Toyota Camry, and 2003-2009 Toyota 4Runner, with repair costs ranging from $1,200 to $3,000.
