Common Questions

What does C0464 mean and how does it affect my car?

C0464 indicates a communication issue in the ABS system that could lead to reduced braking effectiveness. This can affect your car's ability to prevent wheel lockup during hard braking, making it crucial to address immediately.

What are the most common causes of C0464 and how much does it cost to fix?

Common causes include a faulty ABS module (60% chance) and wiring issues. Repair costs range from $100 for wiring repairs to $600 for module replacement, depending on severity.

Can I drive my car with C0464 or should I stop immediately?

It's best to avoid driving if you have the C0464 code, as it indicates potential brake system failure. It’s advised to get it checked as soon as possible to ensure safety.

How can I diagnose C0464 myself using GeekOBD APP?

Using the GeekOBD APP, you can perform a scan to retrieve DTCs, view freeze frame data, and monitor live data from the ABS module, helping you identify specific issues.

What vehicles are most commonly affected by C0464?

C0464 is frequently seen in 2010-2020 Chevrolet Silverado and GMC Sierra models, among others. Check for recalls or technical service bulletins (TSBs) related to ABS issues.

How can I prevent C0464 from happening again?

Regularly inspect your vehicle's electrical systems and wiring, keep software updated, and avoid modifications that can interfere with the ABS system.

What is C0464?

The DTC C0464 is a diagnostic trouble code that indicates a communication issue between the Anti-lock Brake System (ABS) control module and other control modules within your vehicle. Specifically, this code arises when the ABS module fails to communicate properly with the engine control module (ECM) or the vehicle's body control module (BCM). This could lead to issues such as the malfunction of the ABS system, which is critical for preventing wheel lockup during hard braking, potentially compromising vehicle safety. Common in 2010-2020 Chevrolet Silverado, GMC Sierra, and other GM models, this code can trigger the ABS warning light on the dashboard, signaling a malfunction. If left unresolved, the vehicle may experience decreased braking performance, leading to longer stopping distances and increased risk of accidents. Moreover, the C0464 code can result in additional diagnostic trouble codes being stored, complicating the overall diagnostic process. It's essential to address this issue promptly by diagnosing and repairing any faults in the ABS system to ensure the safety of your vehicle and its occupants.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0464 is present:

The ABS warning light illuminates on the dashboard, indicating a potential failure in the braking system.
Loss of ABS functionality during braking, which may cause the wheels to lock up under hard braking conditions.
Increased stopping distances due to the failure of the ABS system to engage properly during emergency braking.
Possible traction control warning lights may also appear, suggesting a broader issue with vehicle stability systems.
Unusual noises from the ABS module during operation, such as grinding or buzzing sounds, which may indicate internal issues.

Possible Causes

Most common causes of C0464 (ordered by frequency):

{'cause': 'Faulty ABS Module', 'likelihood': '60%', 'details': 'The most common cause of the C0464 code is a malfunctioning ABS module itself, which may fail due to electrical issues or internal component failure.'}
{'cause': 'Wiring Issues', 'technicalExplanation': 'Damaged or corroded wiring between the ABS module and other control modules can lead to communication errors, causing the C0464 code to trigger.'}
{'cause': 'Corrupted Software', 'preventionTips': 'Outdated or corrupted software in the ABS module can cause communication failures. Regularly updating vehicle software can help prevent this issue.'}
{'cause': 'Poor Ground Connections', 'details': 'A poor ground connection can interrupt communication lines, resulting in intermittent or complete failure of the ABS module.'}
{'cause': 'Electrical Interference', 'details': 'External electrical interference from aftermarket accessories or faulty components may disrupt communication between modules.'}
