C1252 on Toyota
Manufacturer-Specific Chassis Code (commonly ABS/Brake Pressure or Wheel Circuit)
C1252 on Toyota vehicles indicates manufacturer-specific chassis code (commonly abs/brake pressure or wheel circuit). Au7o has documented this code across 2 Toyota models — most commonly on 4Runner, Camry. 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. Typical repair costs on Toyota range from $1,200 to $3,000, depending on the specific model and root cause.
Common Causes of C1252
- •Faulty brake/ABS pressure sensor or solenoid
- •Wheel speed sensor or related wiring fault
- •Open, short, or corrosion in the ABS circuit
- •Failing ABS/EBCM control module
- •Poor ground or low system voltage
- •Hydraulic control unit internal fault
C1252 on Toyota by Model
Toyota 4Runner(1 issue)
- Brake Booster / Master Cylinder Internal Leak Causing Hard Pedal and Reduced Braking Assist2003-2009
Multiple 4th-generation 4Runner owners report the brake pedal becoming hard, requiring excessive effort to stop, often accompanied by ABS/VSC/TRAC warning lights and a buzzing or continuously running brake actuator. Toyota issued service information for brake booster pump/master cylinder concerns on related platforms, and owner complaints frequently describe internal accumulator or actuator failure rather than simple pad/rotor wear. Repairs are expensive because the booster/master/actuator assembly is typically replaced as a unit.
Toyota Camry(1 issue)
- Brake Actuator / ABS Module Internal Failure Causing Warning Lights and Loss of Assist2007-2017
A well-documented issue on many Camry and Camry Hybrid models is failure of the brake actuator/ABS pump assembly, often accompanied by ABS, brake, traction, and master warning lights. Owners report the pump running frequently or continuously, a buzzing noise from the engine bay, hard pedal feel, and reduced brake assist. On hybrids, this can become especially expensive because the actuator and booster assemblies are complex and labor-intensive to replace.
