The fault is present after the ignition has been switched on and the brake pedal has
been depressed.
The fault appears after a fault on one of the two brake switch contacts.
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.
ET039 must be Released and ET799 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

to seat it completely in its position.
Lock it by turning it an eighth of a turn.
With the brake pedal depressed, measure the resistance of the brake pedal switch, component code 160 between
connections AP1 (for Logan, Sandero, Duster) or AP10 (for Thalia 2/Symbol 2, Clio II F 6, Kangoo VLL) and
65A. The value must be X > 10 M (between 0°C and 40°C).
