| The data bus diagnostic interface Gateway -J533- serves to link different systems of the CAN data bus in the vehicle. It transmits data e.g. from the engine control unit (CAN bus drive) to the dash panel insert (dash panel insert CAN bus). |
| The data bus diagnostic interface Gateway -J533- is monitored by the self-diagnosis and can be tested with the → Vehicle diagnostic tester. |
| Check the databus activity - by doing this test you can notice if each databus (drive, comfort and infotainment) can switch over into the databus resting position (Sleep Mode). |
| Check the system at the databus - by doing this test the connection level of the data bus diagnostic interface to the other system can be checked for data bus. |
