3. CHARGE REFRIGERANT INTO REFRIGERATION
SYSTEM
If there is no leak after refrigerant leak check, charge the proper
amount of refrigerant into the refrigeration system.
CAUTION:

Do not run the engine when charging the system
through the high pressure side.

Do not open the low pressure hand valve when the
system is being charged with liquid refrigerant.
(a) Open the high pressure hand valve fully.
(b) Charge specified amount of refrigerant, then close the
high pressure hand valve.
HINT:
No bubbles in the sight glass indicates that the system is fully
charged.
(c) Partially charge the refrigeration system with refrigerant.
(1) Start engine and race engine at 1,500 rpm.
(2) Set fan speed selector to ºHIº.
(3) Set temperature control to ºMAX. COOLº.
(4) Set air inlet control to ºRECIRCº.
(5) Fully open doors (Sliding roof: closed).
(6) Open the low pressure hand valve.
CAUTION:
Do not open the high pressure hand valve.
(d) Charge refrigerant until bubbles disappear and check the
pressure on the gauge through the sight glass.

ON-VEHICLE INSPECTION
1. INSPECT EXPANSION VALVE
(a) Check amount of gas during refrigeration cycle.
(b) Set on manifold gauge set.
(c) Start the engine.
(d) Operate the A/C system.
(e) Inspect the expansion valve.
(1) Run the engine at 1,500 rpm for at least 5 minutes.
(2) Check the high pressure reading is 1.37 - 1.57 MPa
(14 - 16 kgf/cm
2, 199 - 288 psi).
(3) Check the low pressure reading.
If the low pressure reading is 0 kPa (0 kgf/cm
2, 0psi), replace
the expansion valve.
2. REMOVE REAR DOOR SCUFF PLATE RH
3. REMOVE REAR FLOOR MAT SUPPORT PLATE
4. REMOVE QUARTER TRIM PANEL RH
5. INSPECT THERMISTOR RESISTANCE
(a) Disconnect the connector.
(b) Measure resistance between terminal 3 and 4.
Standard resistance: Approx. 1.5 kW at 25 °C (77 °F)
If resistance is not as specified, proceed ºINSPECTIONº on
page AC-36.
6. INSPECT MAGNETIC VALVE CONTINUITY
(a) Disconnect the connector.
(b) Check the continuity exists between terminal 1 and 2.
If resistance is not as specified, proceed ºINSPECTIONº on
page AC-36.
7. CHECK FOR LEAKAGE OF REFRIGERANT
(a) Remove the power transistor.
(b) Using a gas leak detector, check for leaks of refrigerant.
If there is a leakage, check the evaporator or tightening torque
at the joints.

(b) Without hand-held tester (Using A/T OIL TEMP indicator)
(1) Connect terminals between CG (4) and TC (13) of
the DLC3 using SST (09843-18040).
(2) Move the shift lever back and forth between N and
D at 1.5 seconds interval for six seconds.
(3) The D shift indicator on the combination meter
comes on for two seconds. This indicates that the
fluid temperature check mode has been started.
(4) The D shift indicator comes on again when the fluid
temperature reaches 46C (115F) and blinks
when it exceeds 56C (130F).
(5) Allow the engine to idle until the fluid temperature
reaches 46C (115F).
6. FLUID LEVEL CHECK
NOTICE:
The fluid temperature must be between 46C (115F) and
56C (130F) to check the fluid level.
(a) Remove the overflow plug with the engine idling.
(b) Check that the fluid comes out of the overflow tube.

If fluid does not come out, proceed to step 7.

If fluid comes out, wait until the overflow slows to a
trickle and proceed to step 8.
7. TRANSMISSION REFILL
(a) Install the overflow plug.
(b) Stop the engine.
(c) Remove the refill plug.
(d) Add 0.4 liters (0.42 US qts, 0.35 lmp. qts) of fluid.
(e) Allow the engine to idle and wait for 10 seconds.
(f) Proceed to step 6.
8. COMPLETE
(a) Install the overflow plug with a new gasket.
(b) Stop the engine.
(c) Install the refill plug with a new gasket.
Torque:
20 NVm (205 kgfVcm, 15 ftVlbf) for overflow plug
39 NVm (400 kgfVcm, 29 ftVlbf) for refill plug
