Instrument panel display
The computer manages the data display on the instrument panel relating to engine operation.
There are six functions concerned:
–the On board diagnostics MIL (Malfunction Indicator Lamp),
– pre-postheating,
– the coolant temperature,
– engine problems; Level 1 (non-critical fault) and Level 2 (emergency stop).
– detection of water in the fuel (depending on instrument panel).
These six functions are represented using four indicator lights.
Pre-postheating and electronic fault warning light (Level 1)
This light is used to indicate that the heater plugs are preheating and as a system fault indicator light:
– Continuously illuminated during + after ignition feed: indicates preheating of the heater plugs.
– Flashing after preheating and an automatic 3-second stop indicates a Level 1 fault (the function is not working
optimally and safety levels are reduced). The user must carry out repairs as soon as possible).
Engine coolant temperature warning light (Level 2)
This indicator light is used both as an in-operation indicator light and as a system fault warning light. It illuminates for
3 seconds when the power is switched on (automatic test procedure).
Continuously illuminated during + after ignition feed: indicates engine overheating or a Level 2 fault.
OBD warning light
This warning light is used to alert the driver of any injection faults that could lead to excessive pollution, or if the OBD
system has been deactivated.
The injection computer requests illumination of the OBD warning light for a present fault only after three successive
driving cycles.
The 3 second visual inspection when the ignition is switched on (automatic test procedure managed by the
instrument panel) is carried out by the injection computer.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is present with the engine idling.
Special notes:
If fault DF016 is present: unstable engine speed and even stalling.
Starting difficult or even impossible when cold.
Use the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2 or Kangoo VLL.
K9K 718, 740, 792, 796 engine (Euro 4):
Check the connection and condition of the exhaust gas recirculation valve connector, component code 1460.
Check the connection and condition of the injection computer, component code 120.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or Technical
Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the connector, otherwise
replace the wiring.
Check the insulation and continuity of the following connections:
●3VP between components 1460 and 120,
●3VQ between components 1460 and 120.
If the connection or connections are faulty and if there is a repair procedure (see Technical Note 6015A (Renault)
or Technical Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the wiring,
otherwise replace it.
Check for the supply 13 V < X< 14 V (with the engine running), 11.5 V < X < 12.5 V (with the ignition on and
the engine stopped) on connection 3VP of component 1460.
Check for earth on connection 3VQ of component 1460.
