Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean ABS Sensors

Sub-steps:
1. Locate the ABS sensors at each wheel hub.
2. Remove the mounting bolts securing the sensors.
3. Carefully detach the sensors from their connectors.
4. Clean the sensor tip with a soft cloth and brake cleaner to remove any dirt or debris.
5. Reconnect the sensors and secure them back in place with bolts.

3. Check Brake Fluid and Master Cylinder

Sub-steps:
1. Remove the cap from the master cylinder reservoir.
2. Inspect the brake fluid level; top off with manufacturer-recommended brake fluid if low.
3. Check for any signs of contamination or discoloration in the fluid.
4. If fluid is contaminated, perform a brake fluid flush to replace it with new fluid.

4. Test ABS Pump and Relay

Sub-steps:
1. Locate the ABS pump and relay in the fuse box (refer to the owner's manual for exact location).
2. Use a multimeter to check for voltage at the relay while the vehicle is in the "On" position.
3. If the relay is faulty, replace it with a new one.
4. Test the ABS pump operation by activating the brake pedal to see if the pump engages.
