PR130CRUISE CONTROL SETPOINT
PARAMETER
DEFINITIONIndicates the reference value requested by the driver (in mph (km/h)).
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature
> 80˚C.
Indicates the cruise control cruising speed.
Cruise control can only be activated for a speed V > 18 mph (30 km/h).

PR138RICHNESS CORRECTION
PARAMETER
DEFINITIONThis parameter indicates the richness correction as a %.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Conformity check: Engine running and engine coolant temperature > 80˚C.
This value changes according to the richness signals from the computer.
The value should be:
PR138 ≈ 50%

PR143SELF-ADAPTING RICHNESS GAIN
PARAMETER
DEFINITIONThis parameter brings the richness regulation back to an average nominal value.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature
> 80˚C.
The programming carried out and the corrections made by the adaptive control program enable the computer to
detect any tendency of the injection system to increase or decrease the richness. This enables the richness to be
optimised across all engine operating phases.
The value should be between:
0 < PR143 < 255
PR13 ≈ 128

PARAMETER
DEFINITIONThis parameter indicates the pedal potentiometer gang 1 voltage in volts.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature
