⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems to avoid short circuits.
•Allow the engine to cool before opening the hood to prevent burns.

Symptoms

•Traction control warning light illuminated on the dashboard
•Vehicle skidding or loss of traction during acceleration
•Unusual tire noise when traction control is engaged
•Reduced engine power during traction control activation
•System fails to activate during loss of traction situations

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify potential issues with the traction control system.
2
Inspect the wheel speed sensors for dirt, damage, or disconnection.
3
Check the condition of the traction control module for any visible damage or corrosion.
4
Verify the brake fluid level and condition, as low or contaminated fluid can affect the traction control system.
