900 SE Hatchback L4-1985cc 2.0L DOHC Turbo EFI (1997)
Braking Sensor/Switch: Description and Operation
The control module receives voltage from the brake light switch, when the brake is activated. For example, the brake light switch is used if the
surface is very slippery and the driver decides to pump-brake.
Every time the driver depresses the brake pedal, (when power is fed to the ECU from the brake light switch), ABS control restarts from its starting
position.
