Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not bypass redundant clutch switch logic; low clutch inputs can affect starting and cruise cancel safety.

Useful checks before replacing parts

Measure switch B feed, signal voltage, ground, and continuity while checking the pedal position at the switch change point.
Inspect connector tension, wiring near the pedal, switch adjustment, shared reference circuits, and short-to-ground conditions.
Compare switch A and switch B data to determine whether the module sees a plausible clutch pedal sequence.
