The car's computer that helps with braking is not getting enough power. It's like when your toy doesn't work well because the batteries are low.
The ABS control module requires a specific voltage range to function correctly. If the voltage is too low, it can cause the system to malfunction.
The C0564 code indicates that the ABS (Anti-lock Braking System) control module is detecting a voltage level that is below the threshold required for proper operation. This can affect the ABS system's ability to prevent wheel lockup during braking.
• ABS warning light on
• Reduced braking performance
• Intermittent ABS operation
• Faulty alternator
• Weak or failing battery
• Poor electrical connections

Electrical Issue
• Avoid driving in conditions where ABS is crucial until repaired
• Have a professional inspect the vehicle if unsure
Check vehicle warranty for coverage on electrical components
This code has been reported in vehicles with high mileage or those with electrical system issues.
Moderate – It affects braking safety, so it should be addressed promptly.
Driving with a malfunctioning ABS can increase stopping distances and risk of skidding.
• Vehicle stationary
• Engine running
The ABS control module is typically located near the brake master cylinder or in the engine compartment.
Q: Can I drive with the C0564 code?
A: It's not recommended as it affects braking safety. Get it fixed as soon as possible.
Q: Will replacing the battery fix the C0564 code?
A: It might, if the battery is the cause of the low voltage. However, other components should be checked as well.
