Standard definition

Cruise Control Brake Switch

This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.

In plain English

The cruise control or chassis module has detected an implausible signal from the dedicated cruise control brake switch. This switch is independent from the stop lamp switch and disengages cruise control when the driver brakes.

A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
