Code C1337 Scion Description

The Skid Control ECU (Brake Actuator Assembly) measures the speed of each wheel by receiving signals from the speed sensors. These signals are used for recognizing that all 4 wheels are operating properly. Therefore, all wheel signals must indicate the same speed. The Diagnostic Trouble Code (DTC) will be set when the average speed difference between the front wheel and rear wheel is 4% or more at a vehicle speed of 30 km/h (18.6 mph) or more.
