U660F AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: P0724: Brake Switch "B" Circuit High



P0724 - Brake Switch "B" Circuit High



DESCRIPTION



The purpose of this circuit is to prevent the engine from stalling when the brakes are suddenly applied while driving in the lock-up condition.



When the brake pedal is depressed, this switch sends a signal to the TCM. Then the TCM cancels the operation of the lock-up clutch while braking



is in progress.



MONITOR DESCRIPTION



This DTC indicates that the stop light switch remains ON. When the stop light switch remains ON during "stop and go" driving, the TCM interprets



this as a fault in the stop light switch, illuminates the MIL, and stores the DTC. The vehicle must stop (less than 3 km/h (2 mph)) and go (30 km/h



(19 mph) or more) five times for two consecutive driving cycles in order to set this DTC.
