Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
VSA Control
Oversteer Suppression Control
When the vehicle goes into oversteer, the oversteer suppression control outputs a brake pressure signal through the VSA modulator-control unit that is optimally distributed between the outside front and rear wheels. This action generates a moment that suppresses the oversteer and stabilizes the vehicle.
Understeer Suppression Control
When the vehicle is experiencing understeer, the understeer suppression control outputs a brake pressure signal through the VSA moulator-control unit that is optimally distributed between the inside front and rear wheels. This action generates a moment that suppresses the understeer. Also during acceleration, the PCM outputs an engine torque down signal to increase the drive wheel cornering force to help maintain steerability and improve line traceability.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
