Stop (Brake) Light Switch, Status

The value indicates the status of the stop lamp switch. The engine control module (ECM) sends a signal on the controller area network (CAN) about the position of the stop lamp switch: activated or not activated. The transmission control module (TCM) uses the signal for the internal gear functions and diagnosing the transmission.

Not active = Stop lamp switch off.

Active = Stop lamp switch on.
