Takeaways

• 😀 C1391 code in Toyota Prius Aqua and other hybrid cars can be caused by an issue with the ABS brake system.
• 😀 A common concern with this code is a potential leak, but C1391 doesn't always indicate this problem.
• 😀 The issue often lies with the brake system unit, specifically the hydraulic unit, rather than the electric kit.
• 😀 The electric kit might still be functional, while the hydraulic unit could be the root of the problem.
• 😀 Research is ongoing to pinpoint the cause of leaks within the hydraulic system, but no conclusions have been reached yet.
• 😀 The brake system unit needs to be replaced if the issue persists, as it cannot be repaired at this time.
• 😀 There are no current alternatives for repairing the brake system unit, making replacement the only option.
• 😀 You can purchase a new ABS brake system from the market to replace the damaged one.
• 😀 Alternatively, a used ABS brake system could be an affordable replacement option.
• 😀 This issue primarily affects the hydraulic unit of the ABS brake system, not the electric components.
• 😀 The process of replacing the brake system is necessary for resolving the C1391 code issue.

Q & A

What does the error code C1391 indicate in a Toyota hybrid car?

The error code C1391 indicates a malfunction in the ABS brake system of a Toyota hybrid vehicle, such as the Prius Aqua. It often points to issues related to the hydraulic or electric components of the brake system.

Is leakage a common cause of the C1391 error code in Toyota hybrids?

While many might assume leakage is the cause of the C1391 error, the issue is more likely related to damage in the brake system's electric kit or hydraulic unit rather than an actual leak.

What part of the brake system is usually damaged when the C1391 error occurs?

The electric kit of the brake system may be damaged, and the hydraulic unit, which is connected to it, could also be compromised, even if the electric kit appears to be functioning.

Can the hydraulic unit in the brake system cause the C1391 error without being completely broken?

Yes, the hydraulic unit may still be damaged and contribute to the C1391 error even if it is not fully broken. The failure could be due to internal issues, such as leaks or malfunctions, that are difficult to diagnose.

Are there any known reasons for leaks in the hydraulic system of Toyota hybrid cars?

Currently, there is no conclusive information or clear cause identified for leaks within the hydraulic system of Toyota hybrids, making it challenging to pinpoint why they occur.

What should owners of Toyota hybrids do if their ABS brake system is malfunctioning with error code C1391?

Owners should consult a professional mechanic to assess the brake system and consider replacing the damaged ABS brake system unit. It is essential to address this issue promptly to maintain vehicle safety.

Is it possible to repair the ABS brake system affected by error code C1391?

Currently, repairing the ABS brake system is not a viable option. The only solution is to replace the damaged brake system unit, as alternatives for repair are not available.

Can a used ABS brake system be a reliable replacement for a damaged unit?

While a used ABS brake system may be an option, it may not guarantee the same performance or lifespan as a new unit. It's important to consider the condition and history of the used part before making a decision.

Why is the replacement of the ABS brake system considered necessary for fixing the C1391 error?

Replacement is necessary because the components of the ABS brake system, such as the electric kit and hydraulic unit, are likely damaged and cannot be repaired, which is causing the malfunction indicated by the C1391 error.

What are the risks of not addressing the ABS brake system failure indicated by code C1391?

Not addressing the ABS brake system failure could lead to further damage to the vehicle, affecting braking performance and overall safety. It is crucial to resolve the issue to ensure the vehicle remains safe to drive.
