P0567 — Cruise Control “Resume” Signal #

Note: The definition of this code may vary slightly depending on the OEM (Original Equipment Manufacturer). Always refer to your specific vehicle’s service documentation for precise terminology.

• P0567 — Cruise Control Resume Signal Malfunction (Ford)
• P0567 — Cruise Control Switch Resume Circuit High (Honda)
• P0567 — Cruise Control “Resume” Signal Circuit (Toyota)
• P0567 — Cruise Control Resume Switch Input Malfunction (Mazda)

Summary of code P0567 #

The P0567 code is triggered when the vehicle’s Powertrain Control Module (PCM) detects an abnormal signal in the cruise control “resume” switch circuit. The cruise control system, sometimes referred to as “speed control,” allows the driver to maintain a set speed without keeping their foot on the accelerator pedal. The “resume” function specifically is used to return to a previously set speed after braking or canceling cruise control. When this code appears, it typically means the PCM has found an unexpected voltage or continuity issue in the circuit dedicated to the “resume” switch. This can lead to the cruise control system becoming partially or fully inoperative, affecting driving comfort on highways.

Common symptoms for code P0567 #

A vehicle with a P0567 code will often show clear signs that the cruise control system is not working as it should. While drivability is usually not affected outside cruise control, you may notice some of these issues:

• The cruise control system will not “resume” to the previously set speed.
• The cruise control light may flash or not illuminate at all.
• In some cases, the entire cruise control function may be disabled.
• The “resume” button on the steering wheel or stalk has no effect.
• Intermittent or unresponsive cruise control operation.

Most likely causes of code P0567 #

The P0567 code is most often linked to electrical problems in the cruise control “resume” switch circuit. These issues can range from simple switch malfunctions to more complex wiring or module faults. Here is the typical order of likelihood:

1. Faulty cruise control “resume” switch — The switch may be physically stuck, worn out, or internally open/shorted.
2. Damaged or corroded wiring/connectors — Issues such as frayed wires, moisture intrusion, or loose pins in connectors can interrupt the signal.
3. Defective clockspring — The clockspring is a spiral-wound electrical connector in the steering wheel that can fail and break continuity to steering wheel controls.
4. Faulty PCM or BCM (Body Control Module) — Rare, but possible if all other components test good.
5. Aftermarket accessories or modifications — Poorly installed accessories can interfere with cruise control circuits.

Step-by-step diagnostics for P0567 #

Diagnosing a P0567 code is a systematic process focusing on the switch circuit integrity and related components. Here’s how a technician or advanced DIYer should approach it:

• 1. Confirm the fault — Use an OBD-II scanner to verify the code and check for any related codes.
• 2. Visual inspection — Examine the cruise control switch and its wiring for obvious signs of damage, wear, or corrosion.
• 3. Test the “resume” switch — Use a multimeter to check continuity and operation of the switch itself as per OEM specifications.
• 4. Inspect the clockspring — If the switch is in the steering wheel, verify the clockspring continuity for the relevant circuit.
• 5. Check wiring and connectors — Trace the circuit from the switch to the PCM or BCM, looking for broken wires, poor connections, or signs of water ingress.
• 6. Scan live data — Some scanners can display the status of the cruise control “resume” switch; monitor this while operating the switch.
• 7. Test modules (if needed) — As a last resort, test or substitute the PCM or BCM if all other components are confirmed good.

Possible repairs for code P0567 #

Once the root cause is identified, repairs for P0567 are generally straightforward, targeting the faulty component or wiring. Here are the most common fixes:

• Replace the cruise control “resume” switch if defective.
• Repair or replace damaged wiring or corroded connectors in the switch circuit.
• Replace the clockspring if an open circuit is found within it.
• Secure or properly reroute any aftermarket wiring that may interfere with the cruise control system.
• In rare cases, reprogram or replace the PCM/BCM if internal faults are confirmed.

Is it safe to drive with code P0567? #

Yes, you can generally continue driving with a P0567 code, as it does not affect essential engine or braking functions. However, the cruise control feature may not work correctly, which could be inconvenient on long highway trips. If the circuit shares wiring with other safety systems or if the malfunction light is accompanied by other codes, further investigation is recommended before extended driving.

Vehicles most commonly affected by code P0567 #

While P0567 can appear on almost any modern vehicle with cruise control, it is more often reported on models where steering wheel controls and clocksprings are used extensively. Here are some frequently affected vehicles:

• Ford F-Series trucks and SUVs
• Honda Accord and Civic
• Toyota Camry and Corolla
• Mazda 3 and Mazda 6
• Chevrolet Silverado
• Hyundai Elantra and Sonata

Common mistakes and best practices for code P0567 #

Misdiagnosing P0567 often leads to unnecessary part replacement or unresolved issues. To avoid wasted time and money, keep these points in mind:

• Assuming the switch is always bad without testing continuity and circuit integrity.
• Overlooking the clockspring, especially if other steering wheel controls are also acting up.
• Ignoring intermittent wiring faults that may only appear when the steering wheel is turned.
• Using generic parts instead of OEM-specified switches, which may not be fully compatible.
• Failing to inspect connectors for corrosion or loose pins, especially after water leaks or spills.

Express FAQ for code P0567 #

Here are quick answers to the two most common questions about P0567:

• Q: Will this code cause my car to fail an emissions test?
  A: No, the P0567 code is not emissions-related and should not trigger a test failure.
• Q: Can I reset the code myself if I fix the problem?
  A: Yes, once the fault is repaired, you can clear the code with an OBD-II scanner. If the issue is resolved, it should not return.
