Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, brake fluid, cleaning supplies.
Disconnect the battery to ensure safety while working on the ABS system.

2. Retrieve and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve any stored codes related to the ABS system.
Note the codes for reference, then clear them using the scanner.

3. Inspect and Clean Components

ABS Sensors:
- Locate the wheel speed sensors at each wheel hub.
- Remove any dirt or debris from the sensor area using a clean cloth or brush.
- Reconnect any loose or corroded connectors.
Brake Fluid:
- Check the brake fluid level in the master cylinder reservoir.
- If low, top off with the recommended brake fluid type (DOT 4 for Renault vehicles).

4. Test Electrical Connections

Using a multimeter, check the voltage at the ABS module connector with the ignition on but the engine off.
Ensure that the voltage readings are within the manufacturer's specifications (usually around 12V).
Repair or replace any damaged wiring or connectors.

5. Reassemble and Reconnect

Reassemble any components removed for inspection.
Reconnect the battery after all checks and repairs are performed.
Ensure all tools are removed from the engine bay.
