1.DEF: EOBD
NOTESPriorities when dealing with a number of faults:
Deal with the fault DF084 Actuator relay control circuit or DF046 Battery voltage as
a priority if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is considered present when the engine is running.
Special notes:
CO/CC.1: No injection on cylinder 1. Greatly reduced performance.
OBD warning light illuminated.
CC.0: The injector is still open: there is a risk of the engine stalling or being damaged
when starting. Greatly reduced performance. OBD warning light illuminated.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III, or
MODUS.
Check the condition of the injector no. 1 connector (component code 193).
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise change the wiring.

AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by a check with
the diagnostic tool.

For NEW TWINGO or E33:
Reconnect the injection locking relay connector and reconnect the battery.
If there is still no + 12V present on the connector for injector cylinder 1 with the ignition on, then there is a fault on
the engine fuse and relay box.
Carry out a fault finding procedure on the engine fuse and relay box to check the continuity of the following
connection:
●BP17 between components 120 and 597,
●BP17 between components 1033 and 597.
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, check the battery and run fault finding on the charging circuit (see Technical Note 6014A,
Checking the charging circuit).
For Clio III and MODUS:
Reconnect the Protection and Switching Unit connector and reconnect the battery.
With the ignition on, if the + 12V is still not present on the cylinder 1 injector connector, there is a fault in the
Protection and Switching Unit (UPC).
Run fault finding on the UPC, component code 1337 (see 87G, Engine Compartment Connection Unit).
Check the condition of the connector for the engine management computer (see Wiring Diagram Technical Note
for NEW TWINGO, E33, CLIO III or MODUS, component code 120).
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 connection:
●3CR between the components 193 and 120.
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.
Measure the resistance of the cylinder 1 injector:
If the resistance of the cylinder 1 injector is not between:
11.4
Ω < X < 12.6 Ω at 20 ˚C, replace the injector.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by a check with
the diagnostic tool.
