2 vehicles · 1 makes · $1,200-$2,800 repair
Most Reported On
C1253 is an OBD-II diagnostic trouble code meaning “Brake Booster Pump Motor Circuit (manufacturer-specific).” 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. This code is most commonly reported on 2003-2009 Toyota 4Runner, and 2012-2014 Toyota Camry (Hybrid LE, Hybrid XLE), with repair costs ranging from $1,200 to $2,800.
