– a road test.
Special notes:
–The level 1 warning light is illuminated.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the engine is started,
– a road test.
Special notes:
If the fault is present:
–the level 1 warning light is illuminated for 1.DEF, 3.DEF and 5.DEF,
–the European On Board Diagnostic warning light is illuminated for 2.DEF and
4.DEF,
– the EGR function and turbocharging are inhibited by the engine management
computer,
– engine torque is limited.
Use bornier Ele. 1681 for all operations on the engine management computer
connector.
If faults DF647 and DF038 Computer are displayed at the same time, deal with DF038
Computer first. Then check that the EGR valve is open during idling to make sure that
the programming has not been lost. If the valve does not open, carry out the
programming phase.
Priorities when dealing with a number of faults:
– DF209 EGR valve position sensor circuit,
– DF046 Battery voltage,
– DF012 Sensor supply voltage no. 2,
– DF272 EGR valve control circuit,
if they are present or stored.
For EGR valves with a flat connector, it is not possible to check the sensor resistance.

Only perform these tests if the parameters do not correspond with the system
operation programming.
Engine running, engine coolant temperature > 80°C
This value must be between 20 N.m < PR015 < 40 N.m
