Cruise Control Resume Signal Malfunction
The P0567 code indicates a malfunction in the cruise control resume signal circuit. This typically occurs when the powertrain control module (PCM) detects an incorrect voltage or signal from the resume switch or related wiring. The cruise control system uses the resume switch to return to a previously set speed after being canceled. A fault in this circuit can prevent the resume function from working, though the set and coast functions may still operate.
1. Most Common Causes
- Faulty or worn cruise control resume switch
- Damaged, corroded, or poorly connected wiring in the resume switch circuit
- Short to ground or voltage in the switch wiring
- Defective cruise control relay (if applicable)
- Internal PCM/ECM failure (uncommon)
- Faulty clock spring or steering wheel control module (on vehicles with steering wheel-mounted controls)
2. Symptoms You Will Notice
- Cruise control resume function does not work
- Cruise control may not engage at all
- Cruise control light on dash may flash or stay off
- Possible stored trouble code P0567
3. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm code P0567 and check for other related codes.
Step 2: Inspect the cruise control resume switch for proper operation using a multimeter.
Step 3: Visually inspect wiring and connectors for damage, corrosion, or loose connections.
Step 4: Check the cruise control fuse and replace if blown.
Step 5: Test the brake switch to ensure it is not stuck or malfunctioning.
Step 6: If all else fails, perform a PCM reset or reprogramming as per manufacturer instructions.
4. Frequently Asked Questions
