Code C1404 Description
The C1404 code indicates a malfunction in the rear speed sensor on the left side of the vehicle. The speed sensor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. It is responsible for monitoring the speed of the wheel and sending this information to the vehicle's electronic control unit (ECU). This information is essential for the proper functioning of the ABS and traction control systems, as it helps prevent wheel lock-up during braking and ensures optimal traction on various road surfaces.
Common Causes of C1404
- Faulty rear speed sensor
- Damaged wiring or connectors
- Corrosion or debris affecting sensor performance
- Issues with the ABS module or ECU
- Electrical system malfunctions
Symptoms of C1404
- ABS warning light illuminated on the dashboard
- Traction control system malfunctioning
- Loss of stability and control while driving
- Uneven braking or wheel lock-up during braking
- Inconsistent speedometer readings
How to Fix C1404
- Diagnose the issue using a scan tool to confirm the C1404 code and pinpoint the exact cause of the malfunction.
- Inspect the rear speed sensor, wiring, and connectors for any damage or corrosion. Replace or repair as necessary.
- Test the sensor's output signal using a multimeter to ensure it is functioning correctly.
- Clear the code from the ECU memory and test drive the vehicle to verify that the issue has been resolved.
- If the problem persists, further diagnosis may be needed to check the ABS module or other related components.
