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.
Test Driving Cars Model Year 2002
Drive where other traffic will not be disrupted.
The car must first be calibrated and then test driven if work is carried out on any vital components in the DSTC-system (steering wheel angle sensor, control module DSTC, control module steering angle sensor, brake pressure sensor (1 and 2), power brake booster or active yaw control sensor). Calibrating is carried out using VIDA vehicle communication or according to the last description in this document.
When calibrating in the workshop, position the car on a flat surface with the wheels pointing forward. Turn the steering wheel with the ignition turned on at least 15° to the right or left. Then turn the steering wheel to the center position and start calibrating.
The test drive must include at least one right and one left turn (more than 45°), cover at least 100 meters and a braking from 50 km/h to a standstill.
The car has passed the test if the dynamic stability and traction control (DSTC) system does not light any lamps (the traction control lamp, the ABS warning lamp or the general brake warning lamp).
Calibrate and test drive as above if any work that may have affected the steering and /or the wheel alignment (straight ahead position) has been carried out.
