Solution

1. Preparation

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

2. Inspect and Replace ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove the mounting bolts using a socket wrench.
Disconnect the sensor wiring harness.
Inspect the sensor for dirt or damage and clean if necessary.
If damaged, replace with a new sensor.
Reattach the wiring harness and secure the sensor with mounting bolts.

3. Check and Repair ABS Module and Wiring

Locate the ABS control module, usually near the master cylinder.
Visually inspect the module and wiring for any signs of damage or corrosion.
Use a multimeter to check for continuity in the wiring.
If damaged, repair or replace wiring as necessary.
Ensure all connections are secure and corrosion-free.

4. Brake Fluid Inspection

Open the master cylinder reservoir cap.
Check the brake fluid level; refill if low with the manufacturer-recommended fluid.
Inspect the fluid for contamination; if dirty, flush and replace the brake fluid.

5. Replace Blown Fuses

Locate the fuse box and identify the fuses related to the ABS and traction control systems.
Use a fuse puller to remove the fuses and inspect for any blown fuses.
Replace any blown fuses with the same amperage rating.
