P0567

Cruise Control Off Signal Malfunction

Powertrain Speed/Idle Control Cruise Control Circuit 🟡 Moderate — Fix within a week ⚠️ Drive with Care
💬

What This Actually Means

In plain language — no jargon

Your cruise control system isn't properly receiving the signal to turn off, like a light switch that's stuck. The ECU can't confirm the off command is working when you expect it to.

Symptoms You May Notice

3 known symptoms for this code
Cruise control won't deactivate when brake pedal is pressed
Cruise control indicator stays illuminated on dashboard
Vehicle maintains set speed even when attempting to disable cruise
🔬

How Your ECU Detects This

Technical sensor logic and voltage thresholds

The ECM monitors the cruise control off signal circuit for proper voltage transitions when the driver actuates the brake or cruise off button. It expects a clean signal drop to ground when the off command is triggered. If this signal is absent, delayed, or stuck high, the fault is recorded.

Voltage & Parameter Thresholds

ParameterNormal RangeFault Condition
Cruise Off Signal Voltage 0V when active (brake/button pressed), 5V when inactive Signal stuck above 0.5V or fails to transition within 100ms
Signal Circuit Continuity Resistance <10 ohms when active Open circuit (>500 ohms) or intermittent connection

Diagnostic & DIY Fix Guide

Check these in order — from cheapest to most complex
1
Brake pedal switch
Test brake light activation; replace switch if lights don't work when pedal pressed.
2
Cruise control stalk connector
Inspect and reseat the connector on the steering column for corrosion or loose pins.
3
Cruise control wiring harness
Check for damaged insulation or pinched wires between steering column and ECM connector.

When to See a Professional Mechanic

Not all fault codes are safe to DIY

Code P0567 is a moderate fault. You can generally drive to a workshop, but avoid long trips or high-load driving (motorway, uphill towing) until it is diagnosed. If the code keeps returning after clearing, or if you notice the symptoms listed above worsening, do not delay professional diagnosis. Many moderate codes have multiple possible root causes — a mechanic with live OBD data can identify the exact fault more efficiently than part-by-part trial and error.

Safety note: OBD-II codes identify the system or circuit where a fault was detected — they do not always identify the exact failed component. A professional mechanic using live sensor data will diagnose the root cause more accurately than replacing parts based on the code alone.

How to Clear Code P0567

What happens after you fix the fault

Once the fault is repaired, P0567 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.

The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.

✅ Safe to Clear When
  • Fault has been diagnosed and repaired
  • You want to confirm the repair worked
  • Code appeared after a sensor was cleaned
⚠️ Do Not Clear When
  • Preparing for an emissions/PUC test
  • Root cause is still undiagnosed
  • Check engine light is flashing
Emissions test note: Clearing codes resets OBD readiness monitors. Most vehicles need 50–100 km of mixed driving before monitors complete. Do not clear codes immediately before an emissions or PUC inspection.
