4.DEF: Component in poor condition
NOTESPriorities when dealing with a number of faults:
Firstly, deal with the following faults:
–ignition
DF351 Ignition coil circuit 1-4,
DF352 Ignition coil circuit 2-3,
–fuel supply circuit
DF026 Cylinder 1 injector circuit
DF027 Cylinder 2 injector circuit,
DF028 Cylinder 3 injector circuit
DF029 Cylinder 4 injector circuit,
DF085 Fuel pump relay control circuit,
–engine flywheel signal
DF154 Flywheel signal sensor circuit,
DF457 Engine flywheel target.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the engine has been running for at least 15 minutes.
Special notes:
1.DEF: As soon as the fault is detected, the injection is cut off on the faulty cylinder(s)
to limit the temperature increase in the catalytic converter. The OBD warning light
flashes for as long as the fault is present.
2.DEF: The OBD warning light is continuously lit.
SIM32_V44_DF436/SIM32_V4C_DF436/SIM32_V50_DF436/SIM32_V54_DF436
AFTER REPAIREnsure that all the faults have been dealt with.
Clear the stored faults. Do not clear the programming.
To check that the system has been properly repaired:
–there must be no further electrical faults,
–programming has been carried out,
the engine must be warm (minimum 75˚C), and idling, with all electrical consumers
running for 15 minutes.

NOTESConditions for applying the fault finding procedure to stored faults
The fault is declared present when the ignition is switched on.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Disconnect the battery and the fuel sender.
Check the condition of the fuel pump and sender unit connector (component code 199, for NEW TWINGO or
component code 833 (for E33, CLIO III or MODUS).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the universal bornier to check the insulation and continuity of the following connections:
●AP41 between components 199 and 247 (for NEW TWINGO),
●41B between components 199 and 247 (for NEW TWINGO),
●41A between components 833 and 247 (for E33, CLIO III or MODUS),
●41B between components 833 and 247 (for E33, CLIO III or MODUS).
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 it.
If the fault is still present, test the multiplex network (see 88B, Multiplex).
If the fault is not resolved, run fault finding on the Instrument panel (see 83A, Instrument panel).
If the fault is still present, contact the Techline.
SIM32_V44_DF455/SIM32_V4C_DF455/SIM32_V50_DF455/SIM32_V54_DF455
AFTER REPAIRFollow the instructions to confirm repair:
–If the fault is present, continue to deal with the fault.
–If the fault is stored, ignore it.
Deal with any other faults.
Clear the stored faults.

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 it.
If the fault is still present, there is a fault in the Protection and Switching Unit (the fuel pump relay is in the Protection
and Switching Unit and is not removable) (for CLIO III or MODUS).
Perform fault finding on the UCH (see 87B, Passenger compartment connection unit) (for NEW TWINGO or

For CLIO III or MODUS:
Reconnect the Protection and Switching Unit connector and reconnect the battery.
If there is still no + 12 V on the fuel pump relay connector, there is a fault in the Protection and Switching Unit.
Carry out fault finding on the Protection and Switching Unit (see 87G, Engine compartment connection unit).
If the fault is still present, contact the Techline.
For NEW TWINGO or E33:
Reconnect the battery.
With the ignition on, if the + 12 V is still not present on the fuel pump relay connector, there is a fault in the engine
fuse and relay box.
Carry out fault finding on the engine fuse and relay box to check the 30A fuse and the continuity of the following
connection:
●BP17 between components 120 and 397, 238 and 397.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, check the battery and run fault finding on the charging circuit (see Technical Note 6014A,
Checking the charging circuit).
IF THE PUMP DOES NOT OPERATE
Check that there is an earth on connection MF on the fuel pump, component code 833.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, replace the fuel pump.

WARNING
During this operation, it is essential to:
–refrain from smoking or bringing incandescent objects close to the work area,
–protect yourself against fuel splashes due to residual pressure in the pipes,
–wear safety goggles with side guards,
–wear leaktight gloves (Nitrile type).
IMPORTANT
–To avoid any corrosion or damage, protect the areas on which fuel is likely to run.
–To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components
exposed to the open air.
Remove 1 l of fuel at the fuel filter outlet, in the engine compartment (see MR 385 (Modus), MR 392 (Clio III),
MR 411 (New Twingo), or MR 442 (E33), Mechanical, 19C, Tank, Fuel tank: Draining), using a pneumatic
transfer pump (part no. 634-200) and place it in 1300 ml plastic cup (part no. 77 11 171 413).
Close the plastic cup with its cover (part no. 77 11 171 416) and let the fuel rest for approximately 2 minutes.
This type of plastic cup is used to prepare paint.
Is the fuel cloudy or does it
separate into two parts?Water is present in the petrol; the fuel is not correct.
Drain the fuel circuit, including the tank (see MR 385 (Modus),
MR 392 (Clio III), MR 411 (New Twingo), or MR 442 (E33),
Mechanical, 19C Tank, Fuel tank: Draining).
