Data Bus On Board Diagnostic Interface -J533-

The Data Bus on board diagnostic interface interlinks the different CAN Bus systems in the vehicle.
It transmits data from, for example, the engine control module (drivetrain CAN Bus) to the instrument cluster (instrument cluster CAN Bus).
Fault finding is done using the Vehicle Diagnostic Tester in Guided Fault Finding.
