Symptom: a Nissan Sylphy G11 sedan, the amassed mileage of forty three,000 km, the open air cooling fan at significant speed, although the closure of air cooling elm327 v1.5 admirer will carry on to high-speed operation, and may not stop; when no air-con, in the event the coolant temperature following reaching ninety five, superior speed cooling enthusiast continues to be unable to halt, only to restart the engine immediately after flameout, the cooling supporter to stop working.
Check Analysis: diagnostic examination fault, no fault code is stored. Immediately after analysis, ECM change signal based upon speed, engine coolant gm tech2 scanner temperature, and air-con refrigerant force within the cooling lover handle, then connect the tension gauge to test air con, typical. Suspect a dilemma while using the cooling lover relay, right after changing the clever command module failure remains.
Because no air super mb star c3 conditioning, if the coolant temperature reaches 95 ℃ cooling fans are going to be able to get started operating, indicating coolant temperature signal is normal. Since the air conditioning program to operate appropriately, the ECM can obtain signals air conditioning turned on. Leaving only air-conditioned force sign questionable. Browse data stream located air con launch scanner stress sensor sign voltage is two.201 V. The traditional data must be 1.304V, the air con tension sensor sign indeed inaccurate.
Remedy: Swap the air-con tension sensor.
