Cruise Control Resume Signal
The P0567 code indicates that the powertrain control module (PCM) has detected a malfunction in the cruise control resume signal circuit. This code is set when the voltage or resistance from the cruise control resume switch falls outside the expected manufacturer specifications.
This code primarily affects the convenience of the cruise control system and does not impact the vehicle's core drivability or safety. It can be diagnosed and repaired at your convenience.
Common symptoms
- Check Engine Light is illuminated
- Cruise control system is completely inoperative
- Cruise control will not resume the previously set speed
- Cruise control indicator light on the dash fails to illuminate or flashes
- Other cruise control functions like set or coast may also be disabled
Likely causes
- Faulty cruise control switch (resume button)
- Damaged or broken clock spring in the steering column
- Wiring harness issues (open, short, or high resistance) in the cruise control circuit
- Corroded or loose electrical connectors at the cruise control switch
- Liquid spill damage on the steering wheel controls
- Faulty Powertrain Control Module (PCM) or cruise control module (rare)
What to check before replacing parts
Test the cruise control switch operation using a scan tool.
Look for: Monitor the cruise control switch data PID while pressing the resume button; if the state does not change from off to on, the switch or circuit is faulty.
Inspect the steering wheel cruise control switches for physical damage or sticking.
Look for: Look for buttons that are stuck down, feel gritty, or show signs of liquid spills that could prevent proper electrical contact.
Check the clock spring continuity.
Look for: Test the resistance through the clock spring while turning the steering wheel; infinite resistance or fluctuating readings indicate a broken ribbon cable.
Inspect the wiring and connectors between the steering column and the PCM.
Look for: Look for chafed wires, loose pins, or corrosion in the connectors that could cause an open or short circuit.
Test the voltage and ground at the cruise control switch connector.
Look for: Verify that the switch is receiving the correct reference voltage and has a solid ground; missing voltage points to a wiring or module issue upstream.
