ET079AIR CONDITIONING PRESENT
STATUS DEFINITIONYES: This status indicates that air conditioning is present on the vehicle.
NO: This status indicates that air conditioning is not present on the vehicle.
NOTESThe heating and air conditioning system is present depending on the vehicle's
equipment level.
Conformity check: Engine stopped, ignition on or engine running.
YES or NO, depending on the vehicle equipment.

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.

PR074BATTERY VOLTAGE
PARAMETER
DEFINITIONThis parameter indicates the battery voltage in Volts.
NOTESThere must be no present or stored faults.
Without electrical consumers (radio, air conditioning, fan assemblies, headlights,
etc.).
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80
°C
12 V < PR074 < 14.4 V.
Ignition on then
at idle speedIf the voltage is at minimum:
Check the battery and the charge circuit (see 87B, Passenger compartment connection unit
for the New Twingo or see 87G, Engine compartment connection unit for Clio III, Modus,
Mégane II, Scénic II and Kangoo 2).
If the voltage is at maximum:
Check that the charging voltage is correct with and without electrical consumers switched on.
