check the engine management computer connections.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Check the continuity, absence of interference resistance and insulation from + 5 V and + 12 V of the following
connections:
– Connection code 3ABS,
– Connection code 3ABT,
between components1589 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.
Check the continuity, the absence of interference resistance, and the insulation against earth of the following
connection:
– Connection code 3ABS between components 1589 and 120.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for the earth on the connector of the turbine upstream temperature sensor:
– Connection code 3ABT of component 1589.
Apply TEST 4 Turbocharged air inlet circuit check.
If the fault is still present, warm up the engine until parameter PR064 coolant temperature = 80°C.
Then run the engine at fast idle speed: PR055 engine speed = 1500 rpm for 2 minutes.
If PR667 Turbine upstream temperature remains fixed at 200°C, replace the turbine upstream temperature
sensor.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– particle filter regeneration is inhibited,
– blue/white smoke and black particles coming from the exhaust,
the OBD warning light will illuminate after three consecutive driving cycles (start + 5
seconds, switch off the ignition and wait 40 seconds).
Priorities when dealing with a number of faults:
– DF315 Particle filter diff.* pressure sensor if present or stored
IMPORTANT
In the long term, this fault may lead to premature wear and a greater risk of
turbocharger failure.

Check the status of the differential pressure sensor connector and engine management computer.
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the particle filter is present.
If it is present,
Visually check that the particle filter is in good condition by positioning the vehicle on a lift:
– not damaged (no abnormal welds, if necessary compare it with another vehicle fitted with particle filter),
– if there are After-Sales sleeves, as a result of a previous operation, check that the particle filter's contents were
not emptied out when it was removed.
If the particle filter is not in good condition or is absent:
– Replace the particle filter.
– Switch on the ignition.
– establish dialogue with the injection computer,
– run command SC036 Reinitialise programming,
–select After particle filter replacement as the operation type, then follow the instructions given by the
diagnostic tool,
– switch off the ignition,
– wait for the diagnostic tool message (maximum time 8 minutes): Communication lost with computer:
EDC16C36, check the tool connection and computer supply before switching the ignition back on.
– clear the faults from the computer memory (this operation must be carried out within 3 minutes of the ignition
being switched on).
– Check the weight of soot: PR383 Weight of soot in the particle filter.
– If PR383
≥ 1 g. Apply the procedure of test 12 Manual clearing of the weight of soot.
If the fault is still present, contact the Techline.
