UniversalCruise Control Set Signal Malfunction
The cruise control system has detected a problem with the signal used to request setting a cruising speed. That signal can come from a control switch and is monitored by the vehicle’s cruise control electronics. Cruise control may not set or may work intermittently; this code alone does not prove that a particular part has failed.
⚠️ Before You Begin (Safety First)
Cruise control may be unavailable or behave unpredictably, so avoid using it until the fault is diagnosed. If cruise control will not cancel with its normal controls or the brake pedal, use the vehicle’s safe disengagement procedure and pull over when safe. Do not remove the steering wheel or probe wiring near airbag components; have those checks done by a qualified technician.
Common Symptoms
- Cruise control may not set a speed because the system does not recognize the set request.
- Cruise control may set intermittently if the signal is intermittent.
- The cruise control indicator may not respond as expected, depending on the vehicle.
- There may be no noticeable symptoms if cruise control is not being used.
Common Causes
- A worn, damaged, or intermittently operating cruise-control set switch may send an unreliable signal.
- A loose, damaged, or corroded connector or wire in the set-signal circuit may interrupt the signal.
- A fault in the circuit or in the electronics that receive or interpret the signal may prevent correct monitoring.
Diagnostic Steps
- Note when the fault occurs and whether the set control responds consistently; this can help distinguish an intermittent signal from a complete loss of function.
- Check the owner’s manual for normal cruise-control operation and any relevant dashboard messages or indicators.
- With the vehicle parked, visually inspect accessible cruise-control buttons and wiring for obvious damage. Do not remove steering-wheel trim or probe wiring near airbag components.
- If the problem persists, arrange a scan and circuit diagnosis using service information specific to the vehicle.
When to Call a Professional
A technician can monitor the cruise-control switch status with a scan tool while operating the controls, then inspect the relevant wiring and connectors using vehicle-specific service information. The switch, circuit, and control electronics should be checked before any part is replaced.

Commonly Asked Questions
Does P0568 prove the cruise-control switch needs replacement?
No. The code reports a problem with the set signal, but the switch, wiring, connectors, or receiving electronics could be involved. Diagnosis is needed before replacing parts.
Can I drive with this code?
The vehicle may be driven without cruise control if it otherwise operates normally. Do not use cruise control until the problem is resolved, and stop safely if the system will not cancel as expected.
Why does cruise control fail only sometimes?
An intermittent switch contact or an unstable connection in the signal circuit can cause the set request to be recognized inconsistently. Scan data and circuit checks can help locate the cause.
Will clearing the code fix the problem?
Clearing it may remove the warning temporarily, but it does not repair an underlying signal or circuit fault. The code may return if the condition is still present.
