Vdiag No.: 44, 48
COLD LOOP SUB-FUNCTION (continued 2):
* When the air conditioning is requested with the engine idling and the vehicle speed = 0 mph (0 km/h),
ET022 will always be ACTIVE and ET021 INACTIVE (unless refrigerant pressure > 15 bar, vehicle speed
= 0 mph, and high coolant temperature). The fan assemblies are disabled under certain coolant temperature
conditions when driving.
When the UPC stops receiving multiplex transmissions from the injection, the fan assemblies are
constantly activated.
NOTESOnly check conformity after a full check with the diagnostic tool.
The values shown in this conformity check are given as examples.
Application conditions: Engine off, ignition on.

Vehicle speedPR089: Vehicle
speed.Indicates the vehicle speed in mph.
This parameter is transmitted by the
ABS computer or by the vehicle
speed ECU. This signal is
transmitted to the injection system
on the multiplex network.Test the multiplex network.

Speed request
for fan
assembly*ET022: Low speed
fan assembly
request.
INACTIVE.The injection requests the UPC to
start the fans.
- INACTIVE: Because engine speed
= 0 rpm.
- ACTIVE: Engine speed = idle
speed, correct refrigerant pressure
and vehicle speed = 0 mph (km/h),
or high coolant temperature.NONE
Speed request
for fan
assembly*ET021: High speed
fan assembly
request.
INACTIVE.The injection requests the UPC to
start the fans.
- INACTIVE: Because engine speed
= 0 rpm.
- ACTIVE: Engine speed = idle
speed. Refrigerant pressure
> 15 bar, vehicle speed = 0 mph,
or high coolant temperature.NONE

immobiliser.
INACTIVEIndicates the status of the
immobiliser system.
- INACTIVE: The injection
computer has recognised the
immobiliser code transmitted by
the UCH.
- ACTIVE: The injection computer
has not recognised the
immobiliser code transmitted by
the UCH.If ACTIVE, apply
