NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
8. CHECK FOR A/C SYSTEM LEAK
(a) Install the manifold gauge set.
(b) Recover the refrigerant from the A/C system using a refrigerant recovery unit.
(c) Evacuate the A/C system and check that vacuum can be maintained.
OK:
Vacuum can be maintained in the A/C system.
HINT
If vacuum cannot be maintained in the A/C system, there may be a refrigerant leak. In this case, it is necessary to repair or
replace the leaking part of the A/C system.
NG -- REPAIR A/C SYSTEM LEAK
OK -- Continue to next step.
9. CHARGE REFRIGERANT
(a) Add an appropriate amount of refrigerant See: Heating and Air Conditioning/Service and Repair.
NEXT -- Continue to next step.
10. RECHECK FOR DTC
(a) Recheck for the DTC when the following conditions are satisfied.
NOTICE:
If refrigerant pressure on the high pressure line is excessive, this DTC will be set. Therefore, it is necessary to measure the voltage
over a period of time (approximately 10 minutes) because this DTC may be set after the A/C has been operating for a while.
HINT
When the outside air temperature is low (below -1.5锟斤拷C (29.3锟斤拷F)), the compressor stops due to signals from the ambient
temperature sensor and the evaporator temperature sensor to prevent the evaporator from freezing. In this case, perform the
inspection in a warm indoor environment.
