1.14.3 OBD Connections
The new generation of GAS control units makes it possible to acquire information useful for properly setting up the
vehicle, through the vehicle’s OBD-connection.
Several carburetion parameters acquired from the PETROL control unit can be monitered, using the special
software for connecting the GAS control unit to the PC, such as:
- Carburetion calibrators (Fast Fuel Trim and Slow Fuel Trim).
- Voltage on the rear lambda probe.
Connect a OBD2-scantool to the car and check the type of connection.
If the tester reads connection types 1,2, or 3, proceed by following the diagram in figure 1.
If the tester reads connection types 6, 7, 8 or 9, proceed by following the diagram in figure 2.
ATTENTION: If the tester (CODE AEB214) reads a type of connection that is not stated above, do not
connect to any of the signals.
