3) Ambient air, pressure, temperature sensor (AAPTS)
General The AAPTS sensor is the all-in-one sensor for engine ambient tempera-
ture and engine ambient pressure. In cowled engine installations it has to
be mounted in the engine compartment in a ram air free area and close to
the air inlet. The sensor should measure the correct air inlet temperature
and the air pressure right before the air filter.
4) Maintenance tool
General For engines of the ROTAX 912 i Series, the maintenance and diagnostic
software B.U.D.S. Aircraft is available. This provides not only the reading
of ECU logs, it also provides a variety of functionalities to support trou-
bleshooting of the engine. To start this software and connect the engine
with a computer a B.U.D.S. Aircraft kit is required. This is a USB adapter,
that provides different software functionalities depending on its version.
4.1) Pin assignment of maintenance and diagnostic interface
Pin assignment See Fig. 6.
Pin assignment for Sub-D DE9 (9-pin) of maintenance and diagnostic
interface.
NOTE: The positions of the individual pins on the 9-pin Sub-D
DE9 connector are numbered.
NOTE: It is recommended not to connect maintenance and diag-
nostic interfaces LANE A and LANE B together.
Impedance If the ECU is connected with the Maintenance and Diagnostic Sub-D DE9
DE9 (9-pin) connector, the impedance between CAN_HIGH_2_A
(CAN_HIGH_2_B) and CAN_LOW_2_A (CAN_LOW_2_B) will be
~60 Ohm.
The AAPTS sensor should not be mounted in the air
intake system between the air filter and throttle body.
