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

Coolant temperature.
Set number of
RCHET111: Set number of
RCH.
YES - NOThe RCHs* are actuated by the UCH.
They are high current consumers.
Consequently, their use is
conditional on the available power
all the time (alternator power).
The injection checks the balance of
available mechanical power
according to the engine operating
conditions (torque, power, etc.) to
authorise, limit, or stop their use.
(This information is sent via the
CAN network to the UCH).
Note: When the RCHs* are actuated,
the injection system must respond
to a fast idle speed request from the
UCH.NONE
