The Toyota Prius ABS C1251 light and the Traction light can turn on due to any problem with braking system. Since most of the Hybrid vehicles use regenerative braking to store electricity, any problem in ABS can cause a decline in the efficiency of vehicle.

Your Prius’s ABS system uses a system of sensors to determine wheel speed when braking. The antilock brake system runs through the ABS module. This module physically controls the anti-lock brake system If it becomes damaged, and can no longer control all four brakes, the Anti-lock Braking System (ABS) light will activate. Typically, corrosion is the most common reason why the module fails.

Toyota Prius ABS Warning Do Not Repair

If you hear any hissing noise then be careful with your cars brakes. This usually represents a failing unit with a leaking accumulator. Although, it depends a lot on the DTC,s stored in the car, we recommend a professional scan tool. Improper fitting of transaxle assembly can cause failure to this system as well. This service involves replacement of unit but is referred to as ABS repair service.

If there is some increase to the individual rate of any of the wheels when accelerating, this wheel receives breaking pressure to reduce the difference. During this time, the electronic control unit changes the torque. The Anti-lock Braking System indicator light does not flash before, during and after the above action, i.e. control unit does not perceive the situation as an error, but as the normal operation of ABS brakes.
