NOTESConditions for application to a stored fault:
The fault is declared present after running command
AC224 Additional fuel circuit pump relay.
See the Wiring Diagrams Technical Note for Logan, Sandero, Kangoo VLL.
Check the supply of the control circuit of the additional fuel supply pump relay with a test light by running command
AC224.
Check the cleanliness and condition of the connector of the additional petrol pump relay, component code 1639
and of the injection computer connector, component code 120.
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector(s), otherwise replace the wiring.
Check the insulation, continuity and absence of interference resistance on the following connection:
–3ACK between components 1639 and 120,
–3FB between components 1639 and 1047.
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 supply of the power circuit of the additional fuel supply pump relay with a test light by running command
AC224. If the check is correct, replace the pump, component code 1639 (see MR 388 (Logan and Sandero) 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, Kangoo VLL.
Check the connection and condition of the connector of the additional fuel circuit solenoid valve, component code
1640 and the injection computer connector, component code 120.
If the connector or connectors are 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.
Check the continuity, insulation, and absence of interference resistance on the following connections:
–3ACM between components 1640 and 120,
–3FB between components 1640 and 1047.
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 supply of the solenoid valve using a test light, by running command AC217 Additional fuel circuit
solenoid valve.
Check the internal resistance of the solenoid valve, component code 1640 on the computer connector; its value
must be between: 12 < X 16 (Duster F4R engine) or 22 < X 30 (Duster K4M engine). If the resistance
is incorrect, replace the solenoid valve.
If the fault is still present, contact the Techline.
