Solution

1. Preparation

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

2. Check and Replace ABS Fuse

Locate the fuse box (refer to the owner's manual for exact location).
Remove the cover and locate the ABS fuse.
Use a multimeter to check for continuity; replace the fuse if it is blown.
Reinstall the fuse cover and reconnect the battery.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Clean the sensor area with a soft cloth to remove dirt and debris.
Check for damage or disconnection; reconnect or replace if necessary.

4. Brake Fluid Check and Replacement

Open the brake fluid reservoir under the hood.
Check the fluid level; it should be between the minimum and maximum marks.
If fluid is low, add the recommended brake fluid type (usually DOT 3 or DOT 4).
If the fluid is contaminated or discolored, perform a brake fluid flush.

5. Test ABS Module and Pump

With the battery reconnected, turn the ignition to the "ON" position (do not start the engine).
Listen for the ABS pump activation sound; this indicates that the system is functioning.
Use a multimeter to check voltage at the ABS module connector; compare readings to specifications in the service manual.
