Tips on exploitation of the car information system
  1. When using any type of system it is essential to first understand the basic graphic symbols.
  2. You should not overload the system with the files not concerning driving process or route. It will allow to analyze sensor readings faster and avoid possible mistakes.
  3. Estimated traffic forecast on the remaining amount of fuel is calculated taking into account the contingency reserve. So you better refill your car if the fuel-level indicator is near 0.
  4. Master or keep handy the computer codes chart. The system displays as two-digit numbers minor failures which do not require instant solving. There may be up to a hundred codes in the system.

  • Display’s failures or mechanical damage;
  • Software breakdown.
Signs of information system parts’ failure
  • Indication of car components failure with no other signs of the breakdown;
  • Too long analysis of sensor value;
  • Frequent rebooting the system under load;
  • Incorrect values of route data.
Causes of information devices failure
  • Tear wear or damage of sensors;
  • Break or short circuit of electrical contact;
  • Damage to the system case, circuits and boards;
  • Ingress of moisture on system components;
  • Using low quality sensors or improper electronic system components;
  • Impact of high temperature swings;
  • Detachment or disconnection of circuit boards contacts, circuits and cables.
Repair of information and communication system of the car

Information system problems can be divided in 2 types: sensors failure or breakdown of the central computer. You can change the sensors in a service center. According to computer readings you can easily spot the failure of a certain sensor.

Breakdown of the main system is a more serious matter. In case of a software breakdown it is necessary to install a new operation system and customize analysis of the system information again. In case of board or circuit damage it is necessary to resolder the chips or replace it. It is essential that the new part is the full analog of the previous one. Otherwise no one can guarantee correct work of the whole system.

For analyzing the trip computer operation the service center runs computerized diagnostics. There are no definite instructions on the frequency of it. It is only recommended to remove the casing and dust the computer once in 1-2 years. You better leave it to professionals too in order not to damage the contacts.
