ISO 9141 interface
The serial interface can also be used as diagnostic interface to
ISO 9141. Via the system flag ISO_DIRECTION you can switch
between 'Send data' and 'Receive data'. The ISO interface is a
special type of serial interface for communicating with diagnostic
interfaces in the vehicle.
For using the ISO interface hardware and software adaptations
are required which are not included in the standard units.
If the ISO interface is used, the serial interface is not available
to the user for program download and debugging. Program
download and debugging are
only
possible via the
CAN
interface
.
The function is only available with the test input 'open'.
