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

conditions when driving.
When the UPC stops receiving multiplex transmissions from the injection, the fan assemblies are
constantly activated.
