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.
