I -POWER ASSISTED STEERING PRESSOSTAT/
INJECTION COMPUTER CONNECTION (IF THE
VEHICLE IS EQUIPPED WITH POWER ASSISTED
STEERING)
The injection computer receives a signal from the
power assisted steering pressostat (can be seen on the
diagnostic tool). This depends on the pressure in the
hydraulic circuit and on the fluidity of the power assis-
ted steering fluid. The higher the pressure, the more
energy is used by the power steering pump.
The idle speed can be approximately 100 rpm faster on
some versions.
II - ELCTRICAL CORRECTION ACCORDING TO
BATTERY VOLTAGE AND ELECTRIC POWER
BALANCE
The purpose of this correction is to compensate for the
drop in voltage due to a power consumer being swit-
ched on when the battery is not sufficiently charged. To
do this, the idle speed is increased, allowing the rota-
tion of the alternator to be increased and, consequent-
ly, the battery voltage.
The lower the voltage, the greater the correction. Cor-
rection of the engine speed is therefore variable. It be-
gins when the voltage drops below 12.8 V. Correction
begins at the nominal engine idle speed and may in-
crease by no more than an additional 150 rpm.
