P0568 – Cruise Control Set Signal

P0568 is a diagnostic trouble code that points to a problem in your cruise control system, specifically with the “set” or “resume” signal circuit. While it usually will not leave you stranded, it can be annoying and may hint at deeper electrical issues if ignored. In this guide, you will learn what P0568 actually means, the most common causes, symptoms you will notice while driving, and how a mechanic would diagnose and repair it. You will also see typical repair costs and whether it is safe to keep driving.

What Does P0568 Mean?

P0568 is defined as “Cruise Control Set Signal Malfunction” (sometimes worded as “Cruise Control Resume/Set Signal”). Your vehicle’s ECU (engine control unit) is not seeing the correct electrical signal from the cruise control switch when you try to set or resume your speed.

The fault is usually in the steering wheel or column switch, the clockspring (spiral cable), wiring, or sometimes the body control module (BCM) or ECU input. The code does not mean your engine has a major fault; it means the control module is not happy with the cruise control command circuit.

Quick Reference

• Code: P0568 – Cruise Control Set/Resume Signal Malfunction
• Severity: Low to moderate (comfort and convenience issue)
• Primary system: Cruise control / steering wheel switch circuit
• Typical symptoms: Cruise inoperative, cruise light issues
• Common causes: Faulty cruise switch, clockspring, wiring fault

Real-World Example / Field Notes

In the shop, P0568 often shows up on vehicles where the owner says, “Cruise worked on and off for a while, now it’s dead.” On a late-model sedan I worked on, the cruise indicator would light up but refused to set speed. Scanning the ECU showed P0568 stored. Testing at the steering wheel switch revealed an open circuit only when the “SET–” button was pressed. Replacing the switch assembly fixed it immediately. On trucks and SUVs, I have also seen P0568 caused by a worn clockspring after years of turning the wheel, especially when other steering wheel buttons start acting up too.

Symptoms of P0568

• Cruise control inoperative – You cannot set or resume speed at all.
• Intermittent cruise operation – Cruise works sometimes, then drops out.
• Cruise light issues – Indicator may turn on but never engages, or flickers.
• Need to hold button – You may have to press or wiggle the switch to make it work.
• No other drivability changes – Engine power and shifting usually feel normal.
• Other steering wheel buttons failing – Volume, phone, or radio controls may also act up if the clockspring is failing.
• Stored cruise-related codes – P0568 may appear with other cruise or switch DTCs.

Common Causes of P0568

Most Common Causes

• Faulty cruise control switch assembly – Worn contacts inside the “ON/OFF,” “SET,” or “RESUME” buttons cause incorrect resistance or no signal to the ECU.
• Damaged clockspring (spiral cable) – The ribbon cable inside the steering wheel hub breaks or shorts after years of turning the wheel, interrupting the cruise signal.
• Wiring issues in steering column – Chafed, pinched, or corroded wires between the switch, clockspring, and control module cause intermittent or open circuits.
• Poor electrical connections – Loose connectors at the steering wheel, under the dash, or at the BCM/ECU create high resistance or intermittent contact.

Less Common Causes

• Faulty brake or clutch pedal switch – If the ECU thinks the brake or clutch is applied all the time, it may set P0568 and disable cruise.
• Body control module (BCM) fault – On vehicles where the BCM interprets steering wheel switch signals, an internal failure can trigger the code.
• ECU input circuit failure – Rare, but a damaged input pin or internal circuit in the ECU can misread the cruise signal.
• Aftermarket accessories – Poorly installed remote starters, alarms, or audio systems can tap into or damage the cruise control wiring.
• Water intrusion or corrosion – Leaks into the cabin or steering column can corrode connectors and cause signal problems.

Diagnosis: Step-by-Step Guide

You will want a good scan tool (preferably with live data), a digital multimeter, basic hand tools, and wiring diagrams for your specific vehicle. Having access to factory service information or a professional database is a big help.

1. Confirm the code and check for others. Connect a scan tool, read stored and pending DTCs, and note any other cruise, brake switch, or steering column codes. Clear the codes and see if P0568 returns during a short drive.
2. Check cruise control operation. With the engine running at a safe road speed, try turning cruise ON, then press SET and RESUME. Note exactly what works and what does not. This helps narrow the fault to specific buttons.
3. Inspect steering wheel controls. Look for obvious physical damage, sticky buttons, or signs of liquid spills on the cruise control switch. If other steering wheel buttons are also dead, suspect the clockspring.
4. Use live data for switch status. Many scan tools show “Cruise Switch,” “SET,” and “RESUME” status. Watch the data while pressing each button. If the ECU never sees the SET command change, the problem is between the switch and the module.
5. Check the clockspring. With the battery disconnected and airbag precautions followed, inspect the clockspring connectors. If possible, test continuity of the cruise control circuits through the clockspring while gently turning it. An open or fluctuating reading indicates a failing unit.
6. Test the cruise switch resistance/voltage. On many vehicles, the cruise switch sends different resistances or voltages for each button on a single wire. Backprobe the connector and compare readings with the service manual specs while pressing each button.
7. Inspect wiring and connectors. Follow the harness from the steering column down under the dash. Look for rubbed-through insulation, aftermarket splices, corrosion, or loose connectors. Repair or re-pin as needed.
8. Verify brake/clutch switch operation. Check that the brake (and clutch, if manual) switch signals change correctly in live data. A stuck “ON” brake signal can prevent cruise from engaging and may contribute to P0568.
9. Check Mode $06 and freeze frame data. Some vehicles store detailed test results under Mode $06. Review this along with freeze frame data to see vehicle speed, switch state, and conditions when the code set.
10. Evaluate control modules last. Only after the switch, clockspring, wiring, and pedal switches test good should you suspect the BCM or ECU. At that point, a professional-level scan tool and manufacturer-specific tests are recommended.

Pro tip: If multiple steering wheel functions (horn, audio controls, airbag light) are acting up along with P0568, replace the clockspring first. It is a common failure point and often cheaper than chasing intermittent wiring faults for hours.

Possible Fixes & Repair Costs

Most repairs for P0568 are straightforward once the fault is located. Typical fixes include:

• Replacing the cruise control switch assembly – Common on high-mileage vehicles with worn buttons.
• Replacing the clockspring – Necessary when internal ribbon cables break or short.
• Repairing or replacing damaged wiring/connectors – Fixing chafed wires, corroded terminals, or bad splices.
• Adjusting or replacing brake/clutch switches – If they are out of adjustment or internally faulty.
• Reprogramming or replacing BCM/ECU – Rare, but sometimes needed after confirming all external components are good.

In terms of cost, you are usually looking at roughly $100–$200 for a basic diagnosis at a shop, plus parts and labor. A cruise switch replacement might run $150–$350 total. A clockspring replacement often falls in the $250–$600 range depending on vehicle and airbag handling time. Wiring repairs can range from $100 for a simple fix to $500+ if the harness is buried or heavily damaged. Control module replacement and programming can push costs into the $500–$1,000 range, but that is not common for P0568.

Can I Still Drive With P0568?

Yes, you can usually keep driving with P0568 without damaging the engine or transmission. The main issue is that your cruise control may not work or may behave unpredictably. On long highway trips, losing cruise can be tiring and may affect your comfort and attention. If the problem is related to the clockspring, remember that other safety systems, such as the airbag or horn, might also be affected, so you should not delay repairs too long.

What Happens If You Ignore P0568?

If you ignore P0568, you will likely just live without cruise control, but a failing clockspring or wiring can gradually affect more systems, including steering wheel audio controls, horn, and even airbag deployment. Over time, what starts as a convenience problem can turn into a safety concern and a more expensive repair if additional circuits are damaged.
