LAST EGR VALVE OFFSET
PARAMETER
DEFINITIONThis parameter indicates the EGR valve closing ratio for the last EGR valve offset.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C.
The value should be between 10% < PR129 < 40%
In the event of a fault, apply command SC036 Reinitialise programming and select EGR valve.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

CRUISE CONTROL SETPOINT
PARAMETER
DEFINITIONThis parameter indicates the cruise control setpoint.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
No faults must be present.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– or after a customer complaint (lack of power, smoke etc.).
Conformity check with 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).
In the event of a fault, refer to the interpretation of statuses ET042 Cruise control/Speed limiter, ET556 Driver
deactivation of Cruise control/Speed limiter and ET557 Deactivation of Cruise control/Speed limiter by
function.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.
