NOTESPriority for dealing with a combination of faults:
Deal with faults DF084 Actuator relay control circuit or DF046 Battery voltage first
if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault appears after the engine has been running for a timed period of 10 seconds.
Special note:
–OBD warning light illuminated.
Check the cleanliness and condition of the cylinder 4 injector and its connections.
Repair if necessary.
With the ignition on, check for a + 12 V feed on track 1 of the cylinder 4 injector connector.
If +12V is not present:
– disconnect the battery,
– disconnect the connector marked PPM1 from the Protection and switching unit,
– check the cleanliness and condition of the connections,
– using the Universal bornier, check the continuity on the following connection:
Protection and Switching Unit PPM1 connector Track 1 of the cylinder 4 injector
Repair if necessary.
Reconnect the Protection and Switching Unit connector and reconnect the battery.
If the + 12 V feed on track 1 is still not present on the cylinder 4 injector connector with the ignition on, there is a
fault with the Protection and Switching Unit.
Contact the Techline.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Repair if necessary.
Using the Universal bornier, check the insulation and continuity on the following connection:
Computer, connector B, track A3 Track 2 of the cylinder 4 injector
Repair if necessary.
Measure the resistance of the cylinder 4 injector between tracks 1 and 2.
Replace the cylinder 4 injector if the resistance is not 12 ± 5% at 20°C.
If the fault is still present, replace the cylinder 4 injector.
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.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the ignition is switched on or with then engine
running at an engine speed above 600 rpm.
Special note:
–OBD warning light illuminated.
– Throttle valve defect mode type 6.
Check the cleanliness the condition and the assembly of the turbocharging pressure sensor.
Repair if necessary.
If the fault is still present, manipulate the harness so that the status changes (presentstored).
Look for possible damage to the harness, check the condition and connection of the injection computer and
turbocharging pressure sensor connectors.
Repair if necessary.
If the fault is still present, check for the +12V on track 2 of the turbocharging solenoid valve.
If the +12V is not present, check the following connection for insulation, continuity and the absence of
interference resistance:
Turbocharging solenoid valve track 2 track 2 of the PPM1 connector of the Protection
and Switching Unit
Repair if necessary.
If the fault is still present, disconnect the battery and the injection computer.
Check the insulation, continuity and absence of interference resistance on the following connection:
Computer, connector C, track G4 Track 1 of the turbocharging solenoid valve
Repair if necessary.
If the fault is still present, measure the resistance of the turbocharging solenoid valve between tracks 1 and 2.
Replace the turbocharging solenoid valve if the resistance is not:10 kno load
5 kfull load
If the fault is still present, deal with the other faults then proceed to the conformity check.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.

The fault is probably due to a component that can only affect this cylinder:
– check the cylinder 1 injector
– check the condition and conformity of the spark plugs,
– check the cylinder 1 pencil coil.
If everything is in order, check the same components on cylinder 4 (to cover
a possible cylinder recognition error).
– Carry out the steps "according to the repair".
The fault is probably due to a component that affects a pair of cylinders:
– check the relevant ignition coil circuit (apply the fault finding procedure DF720
Ignition coil circuit 1 or DF075 Ignition coil circuit 4),
– check the condition and conformity of the spark plugs.
– Carry out the steps "according to the repair".
AFTER REPAIREnsure that all the faults have been dealt with.
Clear the stored faults. Do not clear the programming.
To check that the system has been properly repaired:
– there must be no further electrical faults,
– programming has been carried out,
– warm engine (minimum 75°C).
– running at idle speed with all electrical consumers drawing power for 15 minutes.
