7.3 NOTES CONCERNING THE LCS/2
PROGRAMMATION
The standard emulation of the lambda sensor is
TYPE OF LAMBDA SENSOR EMULATION
settled as
SQUARE WAVE
. This kind of emulation is used for
the main part of the vehicles and must be changed
only if allowed from the TECHNICAL MANUAL
LANDI RENZO MT012.
The lambda sensor emulation of vehicles with
Monoinjector Bosch (for which the parameter
OF TPS MONO BOSCH
parameter TYPE OF EMULATION GROUND
vehicles the yellow-blue wire of LCS/2 must be con-
nected to the wire n. 2 (and not to the wire n. 4) of
the TPS connector at side of the throttle body.
In the case some error messages are displayed
on the Programmer Tester V05 (or personal com-
puter with Interface Kit V05) as for example '
RESET TESTER ', or in the case it is not possible to
dialogue with LCS/2 Computer remove both fuses
from the computer wiring system and refit these
after 20"; this way, the microcontroller of the LCS/
2 computer will perform a program reset.

point out to the installer or the driver some error
conditions. While the car is running on gas, if the
green led D (letter B Fig. 5) begins flashing slowly,
this indicates that one of the following error condi-
tions has occurred:
lambda sensor is not working;
lambda sensor detects a rich mixture for too long;
lambda sensor detects a lean mixture for too
long;
The type of error, even if no longer indicated the
next time the car is started, is permanently re-
corded in the memory of the LCS-A1 V05. Use the
Programmer Tester V05 or the Interface Kit V05 to
display the type of error and, once the problem
TYPE
has been solved, it can be cancelled from memory.

CARBURATION LEARNING PROCEDU-
RE WITH LCS/2
To learn the carburation with LCS/2 follow listed
instructions:
1) Make sure the electrical connections of the gas
system are made properly according to the spe-
OK TO
cific sheet of the MT012 CAR SHEET TECH-
NICAL MANUAL of the LANDI RENZO After-
Sales Service.
2) Replace the fuses on the wiring (fuses removed
during the installation of LCS/2).
3) Connect the Programmer Tester V05 (or the
personal computer with Interface Kit V05 in-
stalled) to the diagnostic and programming
