The vehicle is fitted in the factory with electronic control units that, among other things, control the engine and the gearbox. The control units also monitor the exhaust system and the airbags.
The control units continually analyse data relevant to the vehicle while you are driving. In the event of faults or anomalies in the vehicle data, only these data are saved. As a rule, faults are shown by the warning lamps in the instrument cluster.
Data saved in the control units can only be read and analysed with special equipment.
A qualified workshop is only able to recognise and deal with faults by using the relevant saved data. Among other things, the saved data may contain the following information:
- Data relating to the engine and the gearbox
- Speed
- Direction of travel
- Braking force
- Seat belt warning system data
The control units installed will not under any circumstances record conversations in the vehicle.
Your vehicle is not equipped with an event data recorder.
In an event data recorder, information about the vehicle is temporarily saved. In the event of an accident, you can therefore obtain detailed information about the course of events. On vehicles with an airbag system, accident-related data such as impact speed, seat belt status, seat positions and trigger times can be saved. The exact information saved depends on the manufacturer.
The installation of an event data recorder is subject to the agreement of the vehicle s owner. This process is governed by legislation in some countries.
There is a diagnostic connection for reading out various control units and the event memory located in the driver’s footwell. Information regarding the operation and status of the vehicle s electronic control units is stored in the event memory. The event memory should only be read out and erased by a qualified workshop.
WARNING
- Improper use of the connection socket for the on-board diagnostic system can lead to malfunctions which could cause in accidents and serious injuries.
- Only have the engine data read out by a qualified workshop.
