STATUS DEFINITIONACTIVE: This status indicates that the brake pedal is depressed.
INACTIVE: This status indicates that the brake pedal is released.
Note:
Statuses ET704 and ET705 should change status at the same time. In the event of inconsistency, refer to the
interpretation of fault DF050 Brake switch circuit.
Conformity check: Engine stopped, ignition on or engine running.

INACTIVEIf the brake lights are working, check the continuity and the absence of interference
resistance between the following connections:
–5A between components 160 and 120,
–BPT between components 160 and 645 (for Mégane II, Scénic II, Modus and Clio III),
–BPT2 between components 160 and 645 (for Kangoo 2),
–AP10 between components 160 and 1016 (for New Twingo),
–65A between components 160 and 645 (vehicle without ESP),
–65G between components 160 and 645 (vehicle with ESP).
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the brake lights are not operational, check:
–the condition and fitting of the brake switch,
–the condition and conformity of the brake lights fuse,
the conformity of the values in the following table:

STATUS DEFINITIONACTIVE: This status indicates that the optional speed limiting function is active.
INACTIVE: This status indicates that the optional speed limiting function is inactive.
NOTESSpecial note:
This status indicates whether the vehicle speed restriction is a customer option, using
command SC040 Speed limiter.
This status is valid only on Kangoo 2
Conformity check: Engine stopped, ignition on or engine running.
"ACTIVE"Vehicle speed restricted using command SC040 Speed limiter. See the interpretation
of parameter PR879 Maximum speed authorized to find the configured speed
restriction.
"INACTIVE"The vehicle has no optional speed restriction.
