⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems.
•Allow sufficient time for brake system components to cool before inspection or repair.

Symptoms

•Traction control warning light illuminated on the dashboard
•Possible loss of traction in slippery conditions
•Engine performance may feel altered or less responsive
•Potential activation of the ABS warning light
•Change in driving stability or handling characteristics

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any related fault codes.
2
Inspect the traction control system wiring and connectors for any visible damage or corrosion.
3
Check the brake fluid level and condition, as low fluid can affect traction control functionality.
4
Verify operation of wheel speed sensors by testing their resistance and output signals.
5
Inspect the ABS module for faults or malfunctions that could affect the traction control system.
6
Test the vehicle’s stability control system components for proper function.
