NOTESPriorities when dealing with a number of faults:
In the event of a combination of faults DF052,
– DF026 Cylinder 1 injector circuit control,
– DF027 Cylinder 2 injector circuit control,
– DF028 Cylinder 3 injector circuit control, and
– DF029 Cylinder 4 injector circuit control.
The fault finding procedure remains the same for DF026 to DF027 which is used to
identify the faulty injector.
Special notes:
When the fault appears, there is engine noise, unstable engine speed, reduced engine
performance and the level 2 warning light comes on.
Use the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2 or Kangoo VLL.
Switch off the ignition.
Check the condition and connection of the injector connectors, component codes 193, 194, 195 and 196.
Check the connection and condition of the injection computer connector, 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.
Switch off the ignition.
Disconnect the injectors (or the injector identified by DF026, DF027, DF028 and DF029) and switch on the ignition
again.
Using the diagnostic tool, check for changes to DF052.
Is DF052 present or stored?

CONTINUED 1
When all the preparations are complete, start the engine and leave it running:
For 30 seconds at idle speed for Euro 4 type engines: K9K 714 - 718 - 740 - 792 - 796.
Let it idle for 2 minutesfor the euro 3 type engines: K9K 790 - 794.
Note:
These time periods must be respected for the test results to be interpreted correctly.
–Run command AC029 High pressure circuit sealing check
.The engine will automatically carry out a cycle of four accelerations to increase the rail pressure and measure
the internal injector leaks under these conditions.
–When the cycle has finished, run command AC029 High pressure circuit sealing test a second time to
obtain the correct return volume reading for each injector.
Switch off the engine at the end of the cycle.
