A switch to dormant mode phase needed in order to configure

[Sarkan]

Can anyone help.
Peugeot 407 2.0HDI 2004 year with SID803 ECU.
There wasn't a cruise control stalk in the car.
I have fitted the cruise control stalk without speed limiter.
I looked at the configuration and turned on the option in BSI.
The display is working when you switch the cruise stalk on.
Cruise control was not included in the engine configuration, and When I change these to present and press configure I get a message saying.

A switch to dormant mode phase needed in order to configure.

If I select the tick it says " turn ignition off " then " wait, "turn ignition on " wait again then
programming failed.
Does anyone know how this works and whether it can work on this model.

see if the pedal contactors lock and clutch, I think it is necessary contactors for speed governor if this information does not arrive the system does not work
