CHECK HARNESS AND CONNECTOR (AIR CONDITIONING AMPLIFIER ASSEMBLY - AIR
CONDITIONING PRESSURE SENSOR)
(a) Reconnect the A34 air conditioner pressure sensor connector.
(b) Disconnect the A14 air conditioning amplifier assembly connector.
(c) Measure the resistance according to the value(s) in the table below.
TESTER CONNECTION CONDITION SPECIFIED CONDITION
A34-2 (PR) - A14-5 (PRE) Always Below 1 Ω
A34-2 (PR) or A14-5 (PRE) - Body ground Always 10 kΩ or higher
REPAIR OR REPLACE HARNESS OR CONNECTOR
8. INSPECT FOR A/C SYSTEM LEAK
(a) Install a 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 in it.
Vacuum can be maintained in the A/C system.
f vacuum cannot be maintained in the A/C system, refrigerant may be leaking from it. In this case, it is
necessary to repair or replace the leaking part of the A/C system.
