Description of On-Board Diagnostics
General Information
From m.y. 2000 >, instrument clusters are integrated into the "Powertrain" CAN Data Bus network (may also be know as "CAN-Bus" or "Data-Bus").
The Data Bus On Board Diagnostic (OBD) interface -J533- (which is integrated into the instrument cluster) enables data to be exchanged between the
various CAN-Bus networks and the Data Link Connector (DLC) "K-wire".
The Data Bus On Board Diagnostic (OBD) interface -J533- has specific On Board Diagnostic (OBD) capabilities via address word 19 "Gateway", and
must always be coded separately from the instrument cluster. See: Programming and Relearning
