C1253 on Toyota
Brake Booster Pump Motor Circuit (manufacturer-specific)
C1253 on Toyota vehicles indicates brake booster pump motor circuit (manufacturer-specific). Au7o has documented this code across 2 Toyota models — most commonly on 4Runner, Camry. C1253 is a manufacturer-specific chassis/brake code, most commonly documented on Toyota and Lexus vehicles where it relates to the brake booster pump motor circuit (some systems also use it for a related ABS hydraulic/sensor fault). The brake/ABS control module detects an electrical problem in the pump motor circuit that pressurizes the hydraulic brake or ABS actuator. Because it affects power-assisted braking and ABS function, it is a serious code that can lengthen stopping distance and should be addressed promptly. The exact meaning can vary by make, so confirm against the vehicle's 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 C1253
- •Faulty brake booster / ABS pump motor
- •Damaged or corroded pump motor wiring or connector
- •Failed pump motor relay
- •Worn-out brake actuator assembly
- •Low or aged brake fluid affecting the pump
- •Faulty ABS/brake control module
- •Poor power or ground to the pump circuit
C1253 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.
