NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
PRESENTThere is a multiplex connection between the injection computer and the automatic
transmission computer.
ABSENTThere is no multiplex connection between the injection computer and the automatic
transmission computer, as there is a manual gearbox.
If there is an automatic transmission and the message ABSENT appears:
Run a multiplex network test (see 88B, Multiplex).
Check the continuity and insulation to earth of the following connections:
•3MS and 3MT between components 119 and 120.
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.

If the connection or connections are faulty and there is a repair procedure
(seeTechnical Note 6015A, Electrical wiring repair, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the resistance is not approximately 300 Ω, check the continuity of the connection
when the button is not pressed.
If there is continuity, replace the +/- control button.
If the connection or connections are faulty and there is a repair procedure
(seeTechnical Note 6015A, Electrical wiring repair, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.

PARAMETER
DEFINITIONThis parameter indicates the accelerator pedal position as a percentage.
NOTESThere must be no present or stored faults.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– after a customer complaint (e.g. lack of power, etc.).
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
If no pressure is being applied to the pedal PR030 = 0%.
In the event of a fault, consult the interpretation of DF196 Pedal sensor circuit gang 1 or DF198 Pedal sensor
circuit gang 2.

Vehicle with the ignition on, and the engine stopped for at least 1 minute:
Compare the values of PR041 Turbocharging pressure and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 is greater than 0.1 bar,
check the value of PR035 by comparing it with the reading on a vehicle in the workshop which is correct.
If the value of PR035 is not correct (difference greater than 0.1 bar between the 2 vehicles), contact the Techline.
Otherwise (when the value of PR035 is correct), replace the turbocharger pressure sensor.
