Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the ON position without starting the engine.
Retrieve and record any ABS-related error codes for further analysis.

3. Inspect and Clean ABS Sensors

Locate the ABS wheel speed sensors on each wheel hub.
Remove any dirt or debris around the sensors using a clean cloth.
Check the sensor connections for damage and secure them if loose.

4. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, top it off with the recommended brake fluid (DOT 4 for most Renaults).
If the fluid is contaminated (dark or dirty), consider performing a brake fluid flush.

5. Replace Faulty Components

If error codes indicate a specific faulty ABS sensor or pump:
- Disconnect the faulty component.
- Remove it using appropriate sockets.
- Install the new component and torque to manufacturer specifications.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any error codes.
Turn the ignition on and ensure the ABS light is no longer illuminated.
