Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the vehicle's battery to ensure safety.
• Allow the vehicle to cool down if the engine was running.

2. Inspect Wheel Speed Sensors

• Locate the wheel speed sensors at each wheel hub.
• Clean any debris or dirt from the sensor area.
• Check the wiring harness for any signs of damage or disconnection.
• If damaged, replace the wheel speed sensor with a new one (follow manufacturer specifications for part numbers).

3. Check ABS Control Module

• Locate the ABS control module, usually found near the brake master cylinder.
• Inspect the module for any signs of moisture or corrosion.
• If necessary, replace the ABS control module. Ensure to follow specific torque values for mounting bolts as stated in the service manual.

4. Brake Fluid Inspection

• Remove the cap from the brake fluid reservoir.
• Check the fluid level; if low, top off with the recommended brake fluid type (DOT 3 or DOT 4 as specified).
• If the fluid appears contaminated, perform a brake fluid flush.

5. Final Assembly

• Reconnect the vehicle's battery.
• Ensure all components are securely fastened and no tools are left in the engine bay.
