Introduction;
This “LAMBORGHINI OBD II DESCRIPTION MANUAL” is intended to be a description of the
strategies implemented by Lamborghini to fulfill CARB requirements for MY 2008 passenger cars for
the On Board Diagnostic systems (OBDII) installed in the Lamborghini Cars.
Due to the fact that both test group 8NLXV05.0406 (L140 Gallardo V10) and test group
8NLXV06.5474 (L147 Murcielago V12) use the same HW (Lie 2003 ECUs), the same software, the
same input / output structure (see table below) and, of course, the same OBDII strategies, Lamborghini
Grouped the two test groups in the same OBDII group 8NL-V. In this manual the calibration parameters
which are different between the two cars will be underlined, otherwise the description should be
considered as common to the two applications.
Lamborghini Engine management is composed by two LIE ECUs (one for each bank), that manage
the engine itself, and a third ECU, called GFA, that manage the auxiliary functions. Both LIEs and GFA
manage the Lamborghini OBDII System. They should be considered as component of the same system.
The Lamborghini Gallardo and Murcielago can be optionally equipped with an electronic
transmission; the system is the same for both cars and consists in a manual transmission (no changes on
the clutch and gear-box) coupled with an electronic-hydraulic control for the movements of the clutch
and for the selection and engagement of the gears. The system is managed by a dedicated TCM.
Due to the statement above, the Lamborghini Engine Control Module and Transmission Control
Module have been developed on the management of the following kind of input / output signal as
described in the tables below.
