REPLACEMENT
1. DISCHARGE REFRIGERANT FROM REFRIGERATION SYSTEM
(a) Turn the A/C switch ON.
(b) Operate the cooler compressor at the engine rpm of approx. 1,000 for 5 to 6 min\
uites to circulate the refrigerant and collect the compressor oil remaining in each component into the cooler compresso\
r as
much as possible.
(c) Shut off the engine.
(d) Let the refrigerant gas out.

2. CHARGE REFRIGERANT
(a) Using a vacuum pump, perform vacuuming.
(b) Charge refrigerant, HFC±134a (R134a).
Standard: 440
30 g (15.51
1.06 oz.)
SST 07110±58060 (07117±58060, 07117±58070, 07117±58080, 07117±58090, 07117±78050, 07117±88060, 07117±88070, 07117±88080)
3. WARM UP ENGINE
4. INSPECT LEAKAGE OF REFRIGERANT
(a) Using a gas leak detector, check for leakage of the refrigerant.
NOTICE:
1CD±FTV Hot gas heater:
Since the system uses a refrigerant filter (fixed valve), sound of the refr\
igerant circulation (hissing
sound) can be heard for approx. 30 seconds after turning the A/C off. T\
his is merely a sound of bal-
ancing the low pressure with the high pressure, not a sound of abnormality.

7. INSPECT SEAT BELT WARNING LIGHT & BUZZER
(a) Check the operation.
(1) Turn the ignition switch to ON and check that the warning light comes on.\
(2) Fasten the outer belt to the inner belt and check that the warning light\
goes out.
(3) Disconnect the connector from the buckle switch and ground the terminal \
on the wire harness
side connector.
(4) Turn the ignition switch to ON and check that the warning light comes on.\
8. INSPECT LOW OIL PRESSURE WARNING LIGHT
(a) Inspect the circuit. (1) Disconnect the connector from the low oil pressure switch.
(2) Turn the ignition switch to ON.
(3) Ground the terminal of the wire harness side connector, then check the low oil pressure warninglight.
Low oil pressure warning light: Come on
