Common Questions
What does C1404 mean and how does it affect my car?
The C1404 code indicates a malfunction in the ABS pump motor circuit, which can lead to compromised brake performance. If this code appears, your ABS system might not function correctly, increasing stopping distances and reducing control, particularly in emergency situations.
What are the most common causes of C1404 and how much does it cost to fix?
Common causes of the C1404 code include wiring issues, a faulty ABS pump motor, and poor connections. Repair costs can vary, but expect $300 to $800 for pump replacement and $150 to $300 for wiring repairs.
Can I drive my car with C1404 or should I stop immediately?
Driving with the C1404 code is not recommended, as it indicates a potential failure in your braking system. While you may still be able to brake, the ABS functionality could be compromised, posing a safety risk.
How can I diagnose C1404 myself using GeekOBD APP?
You can use the GeekOBD APP to scan for the C1404 code, view freeze frame data, and monitor ABS system parameters. Follow the app's prompts to understand the fault context and perform preliminary checks before seeking professional help.
What vehicles are most commonly affected by C1404?
The C1404 code is frequently reported in Toyota and Lexus models from 2000 to 2015, such as the Toyota Camry, Corolla, and Lexus RX series. Keep an eye out for recalls related to ABS issues in these vehicles.
How can I prevent C1404 from happening again?
Regular maintenance, including inspections of the ABS system and keeping wiring connections clean and free of corrosion, can help prevent the C1404 code. Additionally, addressing any brake issues promptly can extend the life of your ABS components.
What is C1404?
The diagnostic trouble code (DTC) C1404 indicates a malfunction in the ABS pump motor circuit, primarily affecting various Toyota and Lexus vehicles. This code typically appears when the vehicle's onboard diagnostic system detects an issue within the Anti-lock Braking System (ABS) related to the pump motor circuit. The ABS pump is crucial for maintaining optimal braking performance during emergency stops or slippery conditions. When the C1404 code is triggered, it means the ABS may not be functioning correctly, which can lead to increased stopping distances and reduced vehicle control. This code can often be accompanied by the illumination of the ABS warning light on your dashboard, alerting drivers to a potential safety concern. In real-world terms, if you experience this code, it's essential to address it promptly to ensure safe vehicle operation and to prevent further damage to the ABS components. Ignoring this issue could lead to more extensive repairs down the line, affecting your vehicle's safety systems.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C1404 is present:
- The ABS warning light on your dashboard may illuminate, indicating a fault in the ABS system.
- You may experience a soft or spongy brake pedal feel, which can affect braking efficiency.
- In some cases, the vehicle may exhibit irregular braking behavior, such as the brakes locking up in slippery conditions.
- Unusual noises from the ABS pump, such as grinding or whirring sounds, can also be a warning sign.
- The vehicle's stability control may activate unexpectedly, especially during cornering or sudden stops.
Possible Causes
Most common causes of C1404 (ordered by frequency):
- The most common cause of the C1404 code is a short circuit or open circuit in the ABS pump motor wiring, occurring in approximately 60% of cases.
- A malfunctioning ABS pump motor itself can also trigger this code, typically due to wear and tear or internal failures.
- Corrosion or poor connections at the ABS module or pump can lead to intermittent issues, making up about 20% of the causes.
- Less common causes include faults in the ABS control module or software glitches, which may require a professional reprogramming.
- In rare cases, a complete failure of the ABS system due to extensive damage or an accident may be the underlying issue.
