Nissan Murano: Heater & Air Conditioning System :: Periodic Maintenance / Performance Test
INSPECTION PROCEDURE
-
Connect recovery/recycling/recharging equipment (for HFO-1234yf) or manifold gauge.
-
Start the engine, and set to the following conditions.
Test condition Surrounding condition Indoors or in the shade (in a well-ventilated place) Nissan Murano Vehicle condition Door Closed Door glass Full open Hood Open Engine speed Idle speed A/C condition Temperature control switch or dial Full cold A/C switch ON Air outlet VENT (ventilation) Intake door position Recirculation Fan (blower) speed Maximum speed set -
Maintain test condition until A/C system becomes stable (approximately 10 minutes).
-
Check that test results of “recirculating-to-discharge air temperature” and “ambient air temperature-to-operating pressure” are within the specified value.
-
When test results are within the specified value, inspection is complete.
If any test result is out of the specified value, perform diagnosis by gauge pressure. Refer to Symptom Table.
