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 Fault Symptoms
If the two brake signals are seen to be inconsistent at any time, a fault condition must be assumed. The accelerator pedal activation signal is set to zero, hence there will be no throttle demand and the engine will remain at idle. If this occurs while in a cruise active mode, the system shall suspend and will disable cruise for the remainder of that journey. The system will register a fault disallowing further operation.
