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.

After repair, check that the catalytic converter was not damaged by the misfire.
To do this, switch on the ignition, run the catalytic converter test SC006 Run OBD test: Catalytic converter and
start the engine (only depress the brake pedal to authorise the starting of the engine,
Do not depress the accelerator pedal or the clutch pedal).
At the end, check the test results:
STATUS1: Fault finding was not performed/impossible to obtain the necessary conditions
STATUS2: The component is in an average condition - sensor OK
STATUS3: The component is in a good condition - sensor OK
STATUS4: The component is in poor condition - replace the catalytic converter (see MR 451 (Duster), MR 423
(Thalia 2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL), Mechanical, 19B, Exhaust, Catalytic
converter: Removal - Refitting).
Note: The catalytic converter procedure is not carried out if a fault is present.
Important: Do not run the procedure if a new catalytic converter is fitted.
