NOTESSpecial notes:
The "injection control unit supply relay" (50A) is located on the relay plate, inside
the engine compartment connection unit.
Engine stalls or is impossible to restart.
If the fault is present:
The level 2 warning light is lit.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
Check the condition of the battery (see MR 392, 385, 364, 370 and 417, Mechanical, 80A, Battery, Battery:
Removal - Refitting) and carry out fault finding on the charging circuit (see Technical Note 6014A, Charging
circuit check or 87G, Engine compartment connection unit).
Check the condition of the injection supply relay.
Check the injection system fuses (see MR 392, 385, 364, 370 and 417, Mechanical, 81C, Fuses, Fuses: List
and location of components).
Check the connection of the injection computer connector, component code120 (see MR 392, 385, 364, 370
and 417, Mechanical, 13B, Diesel injection, Diesel injection computer: Removal - Refitting).
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
With the ignition on, check for + 12 V on connections BP of the UPC computer, component code 1337.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the continuity, insulation and the absence of interference resistance on the following connections:
–3FB1 between components 1337 and 120,
–3FB2 between components 1337 and 120,
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, replace the main relay or test the Protection and Switching Unit computer (see
87G, Engine compartment connection unit).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
