NOTESPriorities when dealing with a number of faults:
–DF026 Cylinder 1 injector control circuit,
–DF027 Cylinder 2 injector control circuit,
–DF028 Cylinder 3 injector control circuit,
–DF029 Cylinder 4 injector control circuit,
the fault finding procedure remains the same, but the combination of faults makes it
possible to identify the defective injector(s).
Special notes:
When the fault occurs: there is engine noise, the engine speed is unstable, the engine
performance is reduced, and the level 2 warning light comes on with the message
Faulty injection displayed on the instrument panel.
See the Technical Note Wiring Diagrams for the vehicle.
Switch off the ignition, check the condition and connection of the injector connectors, component codes 193,
194, 195, and 196.
If the connector(s) are faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s), otherwise replace the wiring.
Switch off the ignition, disconnect the injectors (or the injector identified by faults DF026 Cylinder 1 injector
control circuit, DF027 Cylinder 2 injector control circuit, DF028 Cylinder 3 injector control circuit,
DF029 Cylinder 4 injector control circuit) and switch on the ignition again.
Using the diagnostic tool, check for changes to fault DF052.
Is DF052 present or stored?

–reconnect one of the four injectors,
–switch on the ignition again.
If the fault recurs as present, replace the reconnected injector, component code 193,
194, 195, or 196 (see MR 364 (Mégane II), MR 370 (Scénic II), MR 385 (Modus), MR
392 (Clio III), MR 411 (New Twingo), MR 417 (Kangoo 2), Mechanical, 13B,

1800 miles (3000 km).
Leave the vehicle to run at idle speed until the engine is warm.
When the engine is warm (PR064 COOLANT TEMPERATURE above 77˚C), carry out the following test drive:
–Drive at a speed of up to 30 mph (50 km/h) and change into 5th gear.
–Stay in this gear and perform 8 accelerations from 30 mph (50 Km/h) to 54 mph (90 Km/h).
–At the end of driving: without switching off the ignition, allow the vehicle to run at idle speed for at least
10 minutes.
–Switch off the ignition, and wait 30 seconds.
–switch on the ignition, check that the fault is stored and clear the fault.
