NOTESConditions for applying fault finding procedures to stored faults:
The fault is present when the engine speed is greater than 1000 rpm.
See the Technical Note Wiring Diagrams for the vehicle.
Move the wiring harness between the injection computer, component code 120 and the battery, component
code 107 to see if the status changes (Present Stored).
Look for any wiring damage and check the connection and condition of the battery, component code 107 and its
connections.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Measure the battery voltage when the ignition is switched on.
If the battery voltage is less than 11 V, recharge the battery.
Check the condition and connection of the battery terminals and posts, component code 107.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check the vehicle's charge circuit (see 87B, Passenger compartment connection unit for the New Twingo
or see 87G, Engine compartment connection unit for Clio III, Modus, Mégane II, Scénic II, and Kangoo 2).
Check the connection and condition of connector A (black 32-track) of the injection computer, component
code 120.
Check the connection and condition of the injection locking relay connector, component code 238.
Check the connection and condition of the UPC connectors, component code 1337.
If the connector(s) is 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.

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?
