⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure vehicle is on a flat surface and stable before lifting; wear safety glasses and gloves.
•Check tire pressure and adjust to manufacturer specifications.
•Inspect tread depth; replace tires if tread is below 3/32 inches or unevenly worn.
•Ensure all tires are of the same type and size; replace any mismatched tires.
•Jack up the vehicle and inspect all suspension components for damage or wear.
•Replace any worn or damaged parts such as shocks, struts, or bushings.
•Reassemble and torque all components to manufacturer specifications.
•Inspect brake pads and rotors for wear; replace if necessary.
•Check for leaking brake fluid and repair any leaks in the system.
•Test ABS sensors for proper function using a multimeter; replace faulty sensors.
•Have the vehicle’s wheel alignment checked and adjusted if necessary.
•Balance all four wheels to ensure even tire wear and improve traction.
•Test drive the vehicle under various conditions to check for stability and traction.
•Monitor for any warning lights related to the traction control system.
•Observe tire performance during acceleration and cornering.
•Regularly check and maintain tire pressure.
•Rotate tires according to manufacturer's recommendations to promote even wear.
•Schedule routine brake inspections and replace components as necessary.

Symptoms

•Vehicle feels unstable during acceleration or cornering
•Warning lights related to traction control system (e.g., DSC or ABS) may illuminate
•Unusual tire noise or vibrations
•Slipping sensation during wet or slippery conditions
•Increased stopping distance or poor braking performance

Diagnostic Steps

1
Scan for error codes** using an OBD-II scanner to check for any relevant trouble codes related to the traction control or ABS systems.
2
Inspect tire condition** for wear, uneven tread, or improper inflation; ensure all tires are matched and suitable for the vehicle.
3
Check suspension components** visually for any damage or excessive play, including shocks, struts, and bushings.
4
Examine the brake system** for any issues such as worn pads, leaking brake fluid, or malfunctioning ABS sensors.
5
Test traction control system** activation by performing a controlled acceleration on a slippery surface and observing system response.
6
Assess wheel alignment** and balance to ensure they are within manufacturer's specifications.
