Data interfaces
6 Data interfaces
6.1 ISO interface
The ISO interface is a serial data interface which is standardised according to ISO 9141, and which enables
the exchange of data with the control unit. The ISO interface has the following functions:
●
Diagnosis with SERDIA.
●
Exchange of diagnostic data.
●
Control unit end-of-tape programming (reading and programming of parameters).
●
Execution of engine test functions.
●
Reading of measured and calculated variables.
●
Reading the data recorder out.
6.2 CAN interface
The CAN interface is a rapid serial data bus which is standardised according to SAE J1939, and which ena-
bles the exchange of data between several control units (e.g. EMR, MVS, transmission electronics, traction
control). The CAN interface has the following functions:
●
Exchange of diagnostic data (error messages, deletion of error memory).
●
Reading of measured and calculated variables.
●
Suppression of fuel injection.
●
Reduction of output.
6.3 SAE-J1708/1587 interface
●
Output of all data received via the inputs or via the CAN interfaces.
●
Output of the fault memory.
●
Deletion of all fault messages.
Note:
☞
In the event of communication via the ISO9141 interface, the SAE-J1587 interface is shut-off!
