Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Tools Required: Multimeter, socket set
Locate each wheel speed sensor.
Disconnect the wiring harness from each sensor.
Use a multimeter to check for resistance; values typically should be within 1,000-2,000 ohms. Replace any faulty sensors.

3. Check Brake Fluid Level

Tools Required: Safety glasses
Inspect the brake fluid reservoir located in the engine bay.
If the fluid is low, top it off with the manufacturer-recommended brake fluid (usually DOT 3 or 4).
If the fluid is dirty or contaminated, consider a complete brake fluid flush.

4. Examine ABS Module and Wiring

Tools Required: Visual inspection tools, multimeter
Locate the ABS module under the hood.
Inspect the wiring harness for fraying, corrosion, or loose connections.
Use the multimeter to check for voltage at the module with the ignition on; refer to service manual for specifications.

5. Reset ESC System

After repairs are made, reconnect the battery.
Use the OBD-II scanner to clear any stored error codes.
Start the vehicle and verify that the stability control light remains off.
