P0567 code definition
The P0567 code indicates that there has been a malfunction in the electrical components of the cruise control resume signal circuit, as detected by the PCM.
What the P0567 code means
This code means there is a problem with the cruise control circuit. If the PCM detects an issue with the cruise control, it will run a self-instituted test of the system. If there is an abnormal voltage result within the cruise control resume signal circuit, it will store the P0567 code.
What causes the P0567 code?
The most likely cause of an abnormal voltage/resistance level in the cruise control resume signal circuit is a failed cruise control switch, which can be caused by liquid spilled or dirt build-up on the cruise control components.
Other causes may include:
- Short circuits or open circuits in the cruise control buttons
- Shorted or open wiring
- Damaged connectors within the cruise control system
- Blown fuses, which may indicate a more serious issue
What are the symptoms of the P0567 code?
If this code is present in the PCM, it is likely that the cruise control is nonoperational. The Check Engine lamp will be illuminated, and there may be blown fuses.
How does a mechanic diagnose the P0567 code?
After an OBD-II scanner detects the P0567 code, a technician should begin with a visual inspection of all the electrical wiring and other components of the cruise control system. Any damaged elements should be replaced or repaired as necessary. They should then clear the code and perform a test drive, checking that the cruise control works as it should, and that the PCM does not store the code again.
If it does, the mechanic should begin testing the voltage readings from each component until the proper diagnosis is discovered. It’s important to clear the code and do a road test after each potential solution is attempted, to ensure that no unnecessary repairs are performed.
Common mistakes when diagnosing the P0567 code
When diagnosing the underlying cause of the P0567 code, the most common misdiagnosis is not checking for blown fuses when replacing faulty cruise control components. Blown fuses can cause new components to fail in the future, so these should be checked with any repair.
How serious is the P0567 code?
If the P0567 code is being detected, a vehicle will still be drivable. The cruise control may not be usable, but this should not affect any other function of the vehicle. However, if a fuse is blown, there may be some other minor electrical issues. The P0567 code in the PCM can also cause a vehicle to fail an emissions test. This code indicates a non-urgent, but still important repair, that should be performed when time allows.
What repairs can fix the P0567 code?
There are many ways that a technician can address a P0567 code detection. They include:
- Replacing the cruise control switch.
- Repairing short circuits or open circuits in the cruise control buttons.
- Replacing or repairing shorted or open wiring components.
- Replacing damaged connectors within the cruise control system.
- Replacing blown fuses.
