ET088REQUEST TO START COMPRESSOR
STATUS DEFINITIONACTIVE: the compressor activation request is active.
INACTIVE: the compressor activation request is not active.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant temperature
> 80
°C
ACTIVEStatus ET088 becomes ACTIVE if there has been a request for air conditioning (press
on AC or AUTO button, with maximum cold request) and status ET004 is YES.
The selection is made on the air conditioning control panel, the request for air
conditioning is transmitted to the UCH which in turn transmits the request to the injection
computer which either authorises or does not authorise compressor activation. If the
injection computer authorises activation of the compressor, it sends the compressor
activation request to the UPC and status ET088 Compressor activation request
becomes ACTIVE (Climate control).
If the vehicle is equipped with manual air conditioning, the air conditioning request is
transmitted from the air conditioning control panel to the UCH which then accepts or does
not accept the air conditioning compressor coming on depending on the operating status
of the passenger compartment fan. When the request has been accepted, the request
to switch on the compressor is transmitted to the injection computer which either
authorises or does not authorise the compressor to start.
If the injection computer authorises compressor activation, it sends the compressor
activation request to the UPC and status ET088 Compressor activation request
becomes ACTIVE.
If there has been no compressor activation request and status ET088 remains ACTIVE,
see 62A, Air conditioning.
Note: Compressor operation is only authorised when the engine is running.
Compressor activation is commanded by the UPC.
INACTIVEStatus ET088 is INACTIVE when no air conditioning request has been made. When
compressor activation is not authorised (ET004 is NO or when the driver switches the
air conditioning off.
If a compressor activation request has been made and status ET088 remains INACTIVE
see 62A, Air conditioning.
Note: Compressor operation is only authorised when the engine is running.
Compressor activation is commanded by the UPC.

*RCH = Passenger Compartment Heating Resistors
ET111SET NUMBER OF PASSENGER COMPARTMENT HEATING RESISTORS
STATUS DEFINITIONThis status indicates that the injection computer is blocking any change to the number
of passenger compartment air heating resistors active (active ones are not cut off, but
no more can be added). This freeze in the number of heating resistors is in response to
vehicle needs (availability of power, need for torque etc.).
Conformity check: Engine stopped and ignition on, or engine running and engine coolant temperature
> 80
°C
YESDepending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer sets the number of activated passenger
compartment heating resistors (no more or no fewer than required).
Status ET111 becomes YES when the number of activated passenger compartment
heating resistors is set by the injection computer.
NODepending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer sets the number of activated passenger
compartment heating resistors (no more or no fewer than required). Status ET111
becomes NO if the number of passenger compartment heating resistors engaged can
be freely controlled by the UCH.
