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.

TEST 3 Throttle valve check
NOTESNone.
Check that parameter PR444 Idle speed regulation integral correction is between:
5 N.m < PR444 < 10 N.m (K4M, K7M engine) or -5 N.m < PR444 < 5 N.m (D4D, F4R and K4M engine of Duster).
The attempt is made with the engine idling and warm (75°C), without any electrical consumers switched on. The
value of PR444 must be read at least 20 minutes after the engine coolant temperature has reached 75°C.
If the value of PR444 is greater than 10 N.m (K4M, K7M engine) or 5 N.m (D4D, F4R and K4M engine of Duster),
reprogram the throttle valve using command RZ031 Throttle stop programming.
If the value of PR444 is less than -5 N.m, check the fitting of the throttle and check for possible air leaks (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, 12A, Fuel mixture, Throttle valve: Removal - Refitting).
If the fault is still present, contact the techline.
