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 (0 km/h) 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.

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 to the UCH).
Note: When the RCHs* are actuated, the injection
