Fault finding - Function82D
The ACCESS/SAFETY function is divided into three sub-functions: Access, Protection and Starting.
1. Access
a) Locking/unlocking by the user
The UCH receives the request from the user via the key.
When the key has been authenticated, the UCH executes the user's request (locking, unlocking, etc.).
Locking is indicated by 2 flashes of the direction indicators.
The direction indicators flash once when unlocking takes place (idem when unlocking the tailgate).
The maximum number of keys allocated to one vehicle is 4.
b) Electric Central Door Locking Button
This button enables the vehicle to be locked or unlocked and has no effect if the vehicle has been locked from the
outside.
Pressing the radiofrequency electric central door locking button when a door is unlocked will lock all the doors and
the electric central door locking indicator light will come on.
c) Deadlocking
To have this function, it is necessary to have a top of the range UCH on a right-hand drive vehicle, and configuration
