Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools, brake cleaner, torque wrench.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Check ABS Fuse

Locate the fuse box (refer to the owner’s manual for specific location).
Remove the ABS fuse and inspect it for any signs of damage.
If the fuse is blown, replace it with one of the same amperage.

3. Inspect Wheel Speed Sensors

Locate each wheel speed sensor at the brake assembly.
Disconnect the sensor wiring harness and use a multimeter to check for resistance; compare values to manufacturer specifications.
Clean the sensor and the mounting area to ensure proper contact, then reconnect.

4. Examine Wiring and Connectors

Visually inspect the wiring harness leading to the ABS module for signs of wear, fraying, or corrosion.
Use a multimeter to test for continuity in the wires.
Repair or replace any damaged wiring or connectors as necessary.

5. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the fluid is at the recommended level; if low, top it off with the specified fluid type.
Inspect for any visible leaks around brake lines and fittings.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear any stored ABS error codes.
Test drive the vehicle to check if the ABS light returns.
