⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical components.
•Allow the vehicle to cool before inspecting the brake system.

Symptoms

•Stability control light remains on
•Traction control light may also be illuminated
•Possible rough handling during turns
•Reduced acceleration and power
•Check engine light may be illuminated in some cases

Diagnostic Steps

1
Scan the vehicle's computer using an OBD-II scanner to check for any stored error codes.
2
Inspect wheel speed sensors for damage or disconnection.
3
Check brake fluid level and condition, as low fluid can affect stability control functionality.
4
Inspect the ABS module for faults or wiring issues.
5
Verify the condition of the tires, ensuring they are properly inflated and evenly worn.

Solution

Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid tester
Gather all necessary tools and park the vehicle on a flat, stable surface.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Record any error codes related to the stability control or ABS system.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector and visually inspect the sensor for damage.
Use a multimeter to check the resistance of the sensor; it should be within the manufacturer’s specifications.
If damaged, replace the wheel speed sensor.

4. Check Brake Fluid Level

Remove the brake fluid reservoir cap.
Inspect the fluid level; if low, add the proper brake fluid as specified in the owner's manual.
Check for any leaks in the brake lines or at the master cylinder.

5. Inspect ABS Module

Locate the ABS module, typically found near the brake master cylinder.
Check for any visible damage or loose wiring.
If necessary, perform a continuity test on the wiring to ensure proper connections.
If the ABS module is faulty, replace it.

6. Tire Inspection

Check all tires for proper inflation and uneven wear.
Rotate or replace tires as needed to ensure uniform performance.
