BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS  ELECTRONICALLY CONTROLLED BRAKE SYSTEM(w/ VSC OFF Switch)  P057112  Brake Switch "A" Circuit Short to Battery  


DESCRIPTION

The skid control ECU (brake actuator assembly) receives stop light switch assembly signals and uses them to determine whether or not the brakes are applied.

DTCs may be stored if either of the following occurs:

·

Stop light switch assembly stuck on malfunction.

·

The accelerator and brake pedals are depressed simultaneously.*


HINT:

*: The skid control ECU (brake actuator assembly) may store this DTC upon judging that a stuck on malfunction has occurred when the accelerator pedal and brake pedal are depressed simultaneously. However, this does not indicate a malfunction.


DTC No. Detection Item DTC Detection Condition Trouble Area
