Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and securely lifted on jack stands.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Clean ABS Sensors

Sub-steps:
1. Locate the ABS sensors on each wheel hub.
2. Remove any debris or dirt around the sensors using a clean cloth or compressed air.
3. Inspect the sensor for physical damage; replace if necessary.
4. Reconnect the sensor wiring securely.

3. Check and Replace Brake Fluid

Sub-steps:
1. Remove the master cylinder cap and check the brake fluid level.
2. If low, top off with the recommended brake fluid (DOT 4 for Renault).
3. If the fluid is contaminated, perform a brake fluid flush.
4. Reassemble the master cylinder cap securely.

4. Test ABS Module and Wiring

Sub-steps:
1. Using a multimeter, check the continuity of the ABS wiring from the sensor to the ABS module.
2. If continuity is interrupted, repair or replace the damaged wiring.
3. Reconnect the ABS module connectors securely.

5. Reconnect Battery and Clear Codes

Sub-steps:
1. Reconnect the negative terminal of the battery.
2. Use the OBD-II scanner to clear any stored error codes.
