S15/T15 Sonoma P/U 2WD L4-2.2L VIN 4 (1995)
Brake Signal: Description and Operation
This electrical switch is used to indicate brake pedal status. This switch is normally closed when the brake pedal is not applied. When the brake
pedal is applied the switch will open, changing the signal to the Powertrain Control Module (PCM). The PCM uses this signal to de-energize the
Torque Converter Clutch (TCC) solenoid when brake pedal is applied. The brake switch is located on the brake pedal mounting bracket.
