TEST 1 Fuel supply pump relay check
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Listen for the operation of the fuel supply pump and the fuel pump relay while running command AC015 Petrol
pump relay.
Check the supply of the fuel pump on connection 3NA (for Logan, Sandero, Duster) or 3N (for Thalia 2/Symbol
2) by running command AC015.
Check the continuity, insulation, and absence of interference resistance on the following connections:
For Logan, Sandero, Duster:
–3NA between components 1047 and 833,
–MG between component 833 and earth.
For Thalia 2/Symbol 2, Clio II F 6:
–3N between components 236 and 218,
–M between component218 and earth.
For Kangoo VLL:
–3NA between components 236 and 218,
–MK between component 218 and earth.
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, contact the techline.

Check the continuity, insulation, and absence of interference resistance on the following connections:
For Logan, Sandero, Duster:
–3ACM between components 1640 and 120,
–3FB between components 1640 and 1047,
For Thalia 2/Symbol 2, Kangoo VLL:
–3ACM between components 1640 and 120,
–3FB between components 1640 and 238,
For Clio II F 6:
–3ACM between components 1640 and 120,
–3FB between components 1640 and 983.
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.
Check the supply of the solenoid valve using a test light, by running command AC224 Additional petrol circuit
pump relay.
Check the internal resistance of the solenoid valve, component code 1640 on the connector of the computer,
component code 120. Its value must be between: 24 < X 30 12 £ X £ 16 (Duster F4R engine) or 22
X 30
(Duster K4M engine) (between 0°C and 40°C). If the resistance is not correct, replace the solenoid
valve (see MR 388 (Logan and Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), MR 430 (Clio II F 6)
or MR 374 (Kangoo VLL), Mechanical, 19C, Tank, Fuel pump of the additional fuel tank: Removal -
Refitting).
If the fault is still present, contact the techline.

NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero.
Listen to the operation of the additional fuel pump and of the petrol pump relay of the additional circuit by running
command AC224 Additional petrol circuit pump relay.
Check the supply of the solenoid valve using a test light, by running command AC224.
If the supply is correct, replace the additional fuel pump (see MR 388 or MR 374 Mechanical, 19C, Tank,
Additional fuel tank: Removal – Refitting).
Check the continuity, insulation, and absence of interference resistance on the following connections:
–3ACL between components 1639 and 283,
–NH (for Logan, Sandero, Duster) or M (for Thalia 2/Symbol 2) or MHA (for Clio II F 6) or MH (for Kangoo VLL)
between the earth and 283.
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 checks are correct, run fault finding on the Protection and Switching Unit.
If the fault is still present, contact the techline.
