⚠️ Safety Warnings

Important safety information - read before proceeding

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

Symptoms

•Traction control light remains illuminated on the dashboard.
•Possible decrease in traction during acceleration, especially on slippery surfaces.
•Engine power may be reduced in certain driving conditions.
•Vehicle stability may feel compromised during turns.
•Activation of the ABS light, indicating possible interrelated issues.

Diagnostic Steps

1
Scan the vehicle's computer system using an OBD-II scanner to check for any stored error codes.
2
Inspect the wheel speed sensors for damage or dirt accumulation.

Solution

1. Preparation

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

2. Scan for Error Codes

Use an OBD-II scanner to retrieve and document any error codes.
Clear the codes and see if they reappear after a test drive.

3. Inspect Wheel Speed Sensors

Remove the wheel corresponding to any error codes related to wheel speed.
Clean any dirt or debris from the wheel speed sensor and its connector.
Check for proper alignment and secure attachment of the sensor.

4. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Ensure the brake fluid is at the proper level; top off with the correct type of brake fluid if low.
Inspect for any leaks in the brake lines.

5. Examine the ABS Module

Inspect the wiring harness connected to the ABS module for frays or breaks.
Ensure all connectors are securely attached.
If needed, test the ABS module with a multimeter to check for proper voltage.

6. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test for continuity when the switch is activated.
Replace the switch if it is found to be faulty.
