NOTESPriority for dealing with a combination of faults:
Apply the procedure for dealing with fault DF084 Actuators relay control circuit first
if it is present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared as present at an engine speed above 2000 rpm.
Special note:
– Throttle valve defect mode types 1, 2 and 6.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the computer connections.
Repair if necessary.
Disconnect the connector marked PPM1 from the Protection and Switching Unit.
Check the cleanliness and condition of the connections.
Repair if necessary.
Using the Universal bornier, check for continuity on the following connection:
Computer, connectorB, track M2Protection and Switching Unit PPM1 connector track 1
Repair if necessary.
Carry out fault finding on the Protection and Switching Unit (the Protection and Switching Unit powers the
injection system).
– clean the battery terminals and all connections to the + and the Earth.
– check the battery voltage.
– check the charging circuit (see MR 364 Mechanical, 16A, Starting - Charging).
Repair or replace the faulty components, if necessary.
AFTER REPAIRDeal with any faults detected 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.
