⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems.
•Ensure vehicle is securely raised and supported before working underneath.

Symptoms

•Traction control warning light illuminated on the dashboard
•Reduced engine power during acceleration
•Unresponsive throttle in slippery conditions
•Vehicle stability issues during cornering
•Increased wheel spin during acceleration

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any stored fault codes.
2
Inspect the wheel speed sensors for damage or dirt accumulation.
3
Check the brake fluid level and condition, as low fluid can affect traction control functionality.
4
Verify that the ABS system is functioning properly, as traction control relies on ABS data.
5
Examine the wiring and connectors related to the traction control system for corrosion or damage.
6
Test the stability control module for faults or communication issues.
