Conditions under which the fault appears:
This fault only appears when the computer is reprogrammed after a change of Vdiag.
If the fault is present, display status ET781 Heater plugs in the sub-function Ignition/Preheating.
If status ET781 is STATUS 3, this means that the heater plugs are not configured in the injection computer.
To find out which type of heater plugs are fitted to the engine, look at the colour of the rings on the plugs.
– Slow plugs have a black ring.
– Fast plugs have a white ring.
To configure the type of plugs, run command SC036 Reinitialise programming and select HEATER PLUGS (see

Conditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running above 3000 rpm and during the
turbocharger regulation phase (for at least 10 seconds).
Special notes:
If the fault is present:
–the level 1 and OBD warning lights are lit,
– the vehicle performance is reduced,
– engine torque is limited,
– the turbo function is inhibited,
– particle filter regeneration is inhibited,
– the EGR function is inhibited by the engine management computer,
Check the condition of the turbocharging pressure sensor connector (component code 1071).
Check the condition of the turbocharging solenoid valve connector (component code 1475).
Check the condition of the engine management computer connector (component code 120).
If the 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 continuity and insulation of the following connections:
•3LQ between components 120 and 1071,
•3LP between components 120 and 1071,
•3LN between components 120 and 1071,
