Removal and InstallationNJBT0018+When removing or installing the seat trim, carefully handle it to keep dirt out and avoid damage.
HFor Wiring Diagram, refer to EL-163, ªWiring Diagram Ð HEATED SEAT к.
CAUTION:
+Before removing the front seat, turn the ignition switch off, disconnect both battery cables and wait
at least 3 minutes.
+Do not drop, tilt, or bump the side air bag module installed in the seat. Always handle it with care.
+Disconnect the side air bag harness connector and heated seat harness connector from under the
seat before removing the seat.
+Disconnect the side air bag harness connector before removing the seat back. Refer to RS-33,
ªFront Side Air Bag Moduleº for details.

CSV613 Variable Displacement Compressor
GENERAL INFORMATIONNJHA02061. The CSV613 compressor differs from previous units. The vent temperatures of the CSV613 compressor
do not drop too far below 5ÉC (41ÉF) when:
+evaporator intake air temperature is less than 20ÉC (68ÉF)
+engine is running at speeds less than 1,500 rpm.
This is because the CSV613 compressor provides a means of ªcapacityº control.
2. The CSV613 compressor provides refrigerant control under varying conditions. During cold winters, it may
not produce high refrigerant pressure discharge (compared to previous units) when used with air condi-
tioning systems.
3. A ªclankingº sound may occasionally be heard during refrigerant charge. The sound indicates that the tilt
angle of the swash plate has changed and is not a problem.
4. For air conditioning systems with the CSV613 compressor, the clutch remains engaged unless: the sys-
tem main switch, fan switch or ignition switch is turned OFF. When ambient (outside) temperatures are
low or when the amount of refrigerant is insufficient, the clutch is disengaged to protect the compressor.
5. A constant range of suction pressure is maintained when engine speed is greater than a certain value. It
normally ranges from 147 to 177 kPa (1.47 to 1.77 bar, 1.5 to 1.8 kg/cm
2, 21 to 26 psi) under varying con-
ditions.
In previous compressors, however, suction pressure was reduced with increases in engine speed.

DIAGNOSTIC PROCEDURE FOR MAX HOT DOOR MOTOR CIRCUITNJHA0218
1 CHECK SIGNAL FOR OPEN OPERATION
1. Turn ignition switch to ON position.
2. Set temperature dial to ªFULL COLDº position, and mode control dial to the ªDEF (
)º, ªVENT ()º or ªBI-LEVEL
(
)º position.
3. Set temperature dial to ªFULL HOTº position, and mode control dial to the ªFOOT (
)º or ªFOOT/DEF ()º posi-
tion. At this time, does an approx. 12 volts exist between the max hot door motor harness connector terminal 7 and the
body ground until the max hot door is fully opened?
NHA501
YesorNo
Ye s©GO TO 2.
[If max hot door motor does not operate even if approx. 12 volts exist, then replace max
hot door motor. (Before replacing the motor, check for smooth operation of the door.)]

2 CHECK SIGNAL FOR CLOSE OPERATION
1. Turn ignition switch to ON position.
2. Set temperature dial to ªFULL HOTº position, and mode control dial to the ªFOOT (
)º or ªFOOT/DEF ()º position
3. Set temperature dial to ªFULL COLDº position, and the mode control dial to the ªDEF (
)º, ªVENT ()º or ªBI-
LEVEL (
)º position. At this time, does an approx. 12 volts exist between the max hot door motor harness connector
terminal 6 and the body ground until the max hot door is fully closed?

YesorNo
Ye s©INSPECTION END. (Max hot door motor is OK.)
[If max hot door motor does not operate even if approx. 12 volts exist, then replace the
max hot door motor. (Before replacing the motor, check for smooth operation of the
door.)]
No©GO TO 3.
3 CHECK SIGNAL CIRCUIT
1. Disconnect heater control panel harness connector and max hot door motor harness connector.
2. Check for continuity between heater control panel harness connector terminal 19 and max hot door motor harness con-
nector terminal 6, heater control panel harness connector terminal 21 and max hot door motor harness connector termi-
nal 7.
NHA503
Continuity should exist.
If OK, check harness for short.
YesorNo
Ye s©GO TO 4.
No©Repair harness or connector.
If harness and connector are OK, replace heater control panel.

CONTROL LINKAGE ADJUSTMENTNJHA0219Max Hot DoorNJHA0219S011. Install max hot door motor on heater unit. Ensure that the max
hot door lever is fitted into the slit portion of max hot door link.
2. Connect the max hot door motor harness connector.
3. Turn ignition switch to ªONº position.
4. Turn the temperature control knob to full hot.
5. Check that max hot door operates properly when the mode
control knob is turned to FOOT or D/F, and other positions.
