NOTESConditions for application to a stored fault:
The fault is declared present when the engine is idling.
The fault is declared present:
– After depressing the pedal at least 10 times.
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
With the brake pedal released, check ET039 Brake pedal and ET799 Brake wire contact.
Check that ET039 is Released and ET799 is Inactive.
Check the fitting and mechanical operation of the brake pedal (the pedal returns properly).
If the check is incorrect, check the braking system.
Remove the brake pedal switch, component code 160 (see MR 388 (Logan and Sandero), MR 451 (Duster), MR

Brake pedal: Removal - Refitting) and, without depressing the pedal, press sufficiently on the brake pedal switch
to seat it completely in its position.
Lock it by turning it a quarter of a turn anti-clockwise.
The fault should change from present to stored.
While depressing the brake pedal to the end of travel, check ET039 and ET799.
ET039 must be Depressed and ET799 must be Active.
If the statuses are correct, contact the Techline.
