C0750

What it means

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.

Is it safe to drive?

The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.

• Cruise control brake switch failed or misadjusted

  high

  One of the most commonly reported causes for this code — check this first.

• Wiring or connector fault

  medium

  A plausible cause — test and verify before replacing parts.

• Internal cruise control module fault

  low

  Less common, but worth ruling out after the more likely causes.
