Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Brake Light Switch: Notes
There are two separate Hall Effect brake-switch inputs into the EMS2000 to allow redundant integrity checking. The signal from the Main Brake switch is used in the control of both the Cruise Control and the Drive By Wire systems. If the brake is operated, the system shall suspend the cruise-mode, but shall retain any current valid target-speed in memory. The second switch is used in a safety plausibility check. If at any time the two brake signals are inconsistent, a fault condition is assumed and any accelerator demand will result in no throttle change and the engine will remain at its idle state.
