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

Never run the engine when charging the system
through the high pressure side.

Do not open the low pressure hand a 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:
A fully charged system is indicated by the sight glass being free
of any bubbles.
(c) Charge partially refrigeration system with refrigerant.
(1) Set vehicle in these conditions:

Running engine at 1,500 rpm

Blower speed control set at ºHIº

Temperature control set at ºMAX. COOLº

Air inlet control set at ºRECIRCº

Fully open doors (Sliding roof: closed)
(2) 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.
(e) Replenishment to be 100 ± 50 g after bubbles disapper.

NOTICE:

Do not perform circling calibration of the compass in
a place where the earth's magnetic field is subject to
interference by artificial magnetic fields (under-
ground parking, under a steel tower, between build-
ings, roof parking, near a crossing, near a large ve-
hicle, etc.).

During calibration, do not operate electric systems
(moonroof, power windows, etc.) as they may inter-
fere with the calibration.

If you want to cancel the calibration before it is com-
plete, push the ºMODEº button again.
HINT:
A compass could be magnetized during by vessels of freight
cars. Before delivery, therefore, make sure to perform calibra-
tion and ensure that calibration can be done. If cannot be done
(cannot complete in spite of driving round several times), it may
be caused by magnetization. Demagnetize the vehicle using a
demagnetizer and preform calibration again.
3. PERFORM DEVIATION CALIBRATION
(a) Stop the vehicle and push the ºMODEº button several
times until ºZONE XXº appears on the calender display.
(b) Then push the ºRESET/ADJº button, referring to the fol-
lowing map to select the number of the zone where the
vehicle is.
(c) After calibration, push the ºMODEº button several times
until the calendar display returns to the normal mode.

Start
Mechanical check
Replace sliding roof motor with ECU. Perform forced operation.*
*: Holding the CLOSE/UP (OPEN/DOWN) switch pressed inhibits the jam protection function at approx.
10 sec. after starting the reverse operation.
If the switch remains pressed any longer, the sliding door starts close operation and it stops when
detecting the fully closed position.

WIRELESS DOOR LOCK CONTROL SYSTEM
This system uses the multiplex communication system, so check diagnosis system of the multiplex commu-
nication system before checking the body control system.
Some functions of wireless door lock control system do not operate.
HINT:
Troubleshooting of the wireless door lock control system is based on the premise that the door lock
control system is operating normally. Accordingly, before troubleshooting the wireless door lock control
system, first make certain that the door lock control system is operating normally.
If the trouble still reappears even though there are no abnormalities in any of the other circuits, then
check and replace the Wireless Door Lock Control Receiver as the last step.
