Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic hand tools, and a flashlight.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Scan for Error Codes

Sub-step 2: Turn the ignition key to the "ON" position without starting the engine.
Sub-step 3: Follow the scanner instructions to select the ABS module and read any stored error codes.
Sub-step 4: Record any codes for further diagnosis or repairs.

3. Inspect and Replace ABS Fuse

Sub-step 1: Locate the fuse box, typically found under the dashboard or in the engine compartment.
Sub-step 2: Identify the fuse related to the ABS system using the diagram on the fuse box cover.
Sub-step 3: Remove the fuse using a fuse puller and inspect it for any signs of damage.
Sub-step 4: Replace the fuse with one of the same amperage if it is blown.

4. Repair Wiring and Connectors

Sub-step 1: Visually inspect all wiring connected to the ABS module and wheel speed sensors.
Sub-step 2: Repair or replace any damaged or corroded wiring.
Sub-step 3: Ensure all connectors are clean, secure, and free from moisture.

5. Test and Replace Wheel Speed Sensors (if necessary)
