UCH
VDiag No.: 0F
GENERAL OPERATION
The UCH is involved in the following four functions (shared between several computers):
– Access - Security Function
This function is divided into three sub-functions which are: Access, Protection and Starting (see 82D, Access –
Security).
– Heating and manual air conditioning function.
In this function, the UCH manages the heated rear screen operation indicator lights, heating controls and air
conditioning activation requests, by sending requests to the engine management computer:
– In the case of a vehicle fitted with manual air conditioning, by pressing on the air conditioning button.
– Wiping function
This function is divided into two sub-functions, which are: Wiper control and Wiper power (see 85A, Wiping -
Washing).
– Lighting Function
This function is divided into two sub-functions, which are: Lighting control and Lighting power (see 80D, Lighting).
