Frequently Asked Questions
What is the difference between switch A and switch B?
Switch A and switch B are redundant clutch pedal switches. They serve different but overlapping functions, such as starter interlock, cruise control disable, and shift interlock. Two switches provide redundancy for safety.
Can both switches fail at the same time?
It is uncommon but possible if a shared connector or wiring harness is damaged. If both P0830 and P0835 appear together, check the common wiring and connector first.
Is switch B easy to access?
Yes, like switch A, switch B is located at the clutch pedal bracket area under the dashboard and is usually accessible without removing any panels.
