Defect modes
Motorised throttle valve
In defect mode, the motorised throttle valve can have 6 different statuses.
Type 1
The throttle opening is less than the Safe mode position. The throttle is no longer activated and is
automatically in Safe mode. The ESP, distance control and cruise control/speed limiter systems are
disabled. The automatic transmission is in "Safe mode".
Type 2
The throttle opening is no longer actuated. The engine speed is limited by injection cut-off.
Type 3
Defect mode is associated with restructuring of the pedal setpoints (constant pedal setpoint for each gear).
Type 4
The associated defect mode restricts the throttle opening. The maximum throttle valve opening threshold
results in a speed below 54 mph (90 km/h).
Type 5
The computer no longer processes torque changes requested by the ESP, distance control, cruise control/
speed limiter and automatic gearbox systems.
This defect mode results from a computer malfunction, or a fault with the manifold or turbocharging
pressure sensor.
The system then only uses the accelerator pedal signal.
The ESP, distance control and cruise control/speed limiter systems are disabled. The automatic
transmission system is in Safe mode.
Type 6
The turbocharging valve no longer works.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is present after a road test using the cruise control then the speed limiter
function.
Check the cleanliness and condition of the cruise control/speed limiter on/off switch and its connections.
Repair if necessary
Check for the + 12 V feed on track A2 of the cruise control or speed limiter selector switch connector with
the ignition on.
Repair if necessary.
Disconnect the battery.
Disconnect the computer. Check the cleanliness and condition of the connections.
Use the "Universal bornier" to check the insulation and continuity of the following connections:
Computer, connector A, track A2 Track A3 of the Cruise control - speed limiter on/off switch
Computer, connector A, track C3 Track B1 of the Cruise control - speed limiter on/off switch
Repair if necessary.
If the fault is still present, deal with the other faults then proceed to the conformity check.
AFTER REPAIRDeal with any faults declared by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
