Toyota Corolla Repair Manual: Circuit description

When the brake pedal is depressed, this switch sends a signals to the ecm. Then the ecm cancels the operation of the lockup clutch while braking is in progress.

Monitor description

Monitor description

The circuit prevents the engine from stopping when the vehicle is stopped by sudden braking when the torque converter clutch is in the lockup mode. The ecm receives the signal from the stop light switch at the time brake pedal is depressed. Then, the ecm sends the signal to the lockup solenoid valve not to be in lockup condition. When the stop light switch remains on during stop and go driving, the ecm interprets this as a fault in the stop light switch and the mil comes on. The vehicle must stop and go (3 km/h (2 mph) to 30 km/h (19 mph)) ten times for two driving cycles in order to detect malfunction.
