Brake Pedal Sensors

The brake pedal sensors are integrated
into a single module that is mounted on the
brake pedal bracket.

• Brake Light Switch F

• Brake Pedal Switch F47
Signal application
Both switches supply the Diesel Direct
Fuel Injection Engine Control Module J248
with the "brake activated" signal.
The engine speed is regulated when the
brake is activated for safety reasons,
since the Throttle Position Sensor G79
could be defective.
Effects of signal failure
If one of the two switches fails, Diesel
Direct Fuel Injection Engine Control Module
J248 reduces the fuel quantity.
SSP209/063
Engine performance drops.
