Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a flat surface and securely supported.
Disconnect the battery to prevent electrical shorts.

2. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor connector and visually inspect for corrosion or damage.
Clean the sensor and connector using electrical contact cleaner.
Reconnect and secure the sensor.

3. Check ABS Fuses and Relays

Locate the fuse box as per the vehicle manual.
Use a multimeter to check the continuity of the ABS fuse and replace if necessary.
Test the ABS relay for proper operation and replace if faulty.

4. Inspect Wiring Harness

Trace the wiring harness from the ABS module to each wheel.
Look for signs of fraying or disconnection; repair or replace damaged sections.

5. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the fluid level is at the recommended mark; top off with DOT 3 or DOT 4 brake fluid if low.
Inspect the fluid for contamination; if contaminated, flush the brake system.

6. Test ABS Module

Reconnect the battery.
Turn the ignition on (do not start the engine) and check for ABS system priming sounds.
If necessary, use a multimeter to check for power at the ABS module when the ignition is on.
