على التوالي مع إيه يا باشمهندس ؟
نحن أمام حمل واحد ومصدر كهربائي واحد ؟
يمكن كلامى بالعربى مش واضح
A/C Off or Non–A/C Model
The cooling fan(s) are actuated by the powertrain control module (PCM) in vehicles with an automatic
transaxle or the engine control module (ECM) using
a low–speed cooling fan relay and a high–speed
cooling fan relay. On A/C–equipped vehicles, a series/
parallel cooling fan relay is also used.
The PCM or the ECM will turn the cooling fan(s) on at low speed when the coolant temperature reaches
93C (199F) and high speed at 97C (207F).
The PCM or the ECM will change the cooling fan(s) from high speed to low speed at 94C (201F) and
turn the cooling fans off at 90C (194F).
A/C ON
The PCM or the ECM will turn the cooling fans on at low speed when the A/C system is on. The PCM
or the ECM will change to high speed when the
coolant temperature reaches 115C (239F) or
high–side A/C pressure reaches 1 882 kPa (273
psi).
The cooling fans will return to low speed when the coolant temperature reaches 112C (234F) or
high–side A/C pressure reaches 1 448 kPa (210
psi).
ياريت ناخد بالنا من الكلام على كتاوت الكنترول وتواليه وتوازيه .
...ويعنى أيه التوازى والتوالى فى الدوائر الكهربيه
