C0750: Cruise Control Brake Switch

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.

04 —Severity

Can I drive with C0750?

Moderate

Usually yes, for a short time.

The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.

Why we rate it moderate

  • Usually lights the ABS, traction or stability warning instead of the check engine light

Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.

05 —Diagnosis

How to diagnose C0750

General procedure — follow the service manual for your vehicle
  1. 1

    Confirm the code and save freeze-frame data

    Read the codes with an OBD-II scan tool and note every code, not just C0750. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.

  2. 2

    Fix other faults first

    If other codes are stored, start with power-supply, sensor-circuit and communication codes. They can cause this code as a side effect.

  3. 3

    Check live data

    Watch the related sensor and actuator readings in live data (Cruise brake switch, Cruise control module, Brake pedal assembly) and compare them with expected values in the service information for your vehicle.

  4. 4

    Test the likely causes in order

    Start with the most likely cause and work down: Cruise control brake switch failed or misadjusted; wiring or connector fault; internal cruise control module fault. Test before replacing parts.

  5. 5

    Check for recalls and service bulletins

    Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.

  6. 6

    Clear the code and verify the repair

    After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

C0750 FAQ

What does C0750 mean?

C0750 means “Cruise Control Brake Switch”. 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 C0750 serious? Can I keep driving?

We rate C0750 as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.

What causes C0750?

The most common causes, from most to least likely: Cruise control brake switch failed or misadjusted; Wiring or connector fault; Internal cruise control module fault. Test before replacing parts, because several causes can set the same code.

How much does it cost to fix C0750?

Typical labor is about $40–$190 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.

Can I fix C0750 myself?

DIY difficulty is easy. Many owners can handle it with a scan tool, a multimeter and basic hand tools. Always confirm the cause before buying parts.

Will C0750 clear itself?

If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
