DESCRIPTION=NJHA0207GeneralNJHA0207S01The variable compressor is basically a swash plate type that changes piston stroke in response to the required
cooling capacity.
The tilt of the swash plate allows the piston's stroke to change so that refrigerant discharge can be continu-
ously changed from 6.0 to 125 cm
3(0.366 to 7.628 cu in).

Operation=NJHA0207S021. Operation Control ValveNJHA0207S0201Operation control valve is located in the suction port (low-pressure) side, and opens or closes in response to
changes in refrigerant suction pressure.
Operation of the valve controls the internal pressure of the crankcase.
The angle of the swash plate is controlled between the crankcase's internal pressure and the piston cylinder
pressure.
2. Maximum Cooling
NJHA0207S0202Refrigerant pressure on the low-pressure side increases with an increase in heat loads.
When this occurs, the control valve's bellows compress to open the low-pressure side valve and close the
high-pressure side valve.
This causes the following pressure changes:
+the crankcase's internal pressure to equal the pressure on the low-pressure side;
+the cylinder's internal pressure to be greater than the crankcase's internal pressure.
Under this condition, the swash plate is set to the maximum stroke position.

DEPLOYMENT OF AIR BAG MODULE AND SEAT BELT
PRE-TENSIONER WHILE MOUNTED IN VEHICLE
NJRS0022S03When disposing of a vehicle, deploy air bag module and seat belt
pre-tensioners while they are mounted in vehicle.
CAUTION:
When deploying air bag module or seat belt pre-tensioner,
ensure vehicle is empty.
1. Disconnect both the vehicle battery cables and wait 3 minutes.
2. Disconnect air bag module and seat belt pre-tensioner connec-
tor.
3. Connect deployment tool (SST: KV99106400) to air bag mod-
ule or seat belt pre-tensioner.
For front passenger air bag module, attach deployment tool
adapter (SST: KV99108300) to the tool connector. For front
side air bag module, attach deployment tool adapter [SST:
KV99109000 (For 4-door Sedan) or SST: KV99108300 (For
Hatchback)]. For front seat belt pre-tensioner, attach deploy-
ment tool adapter (SST: KV99108200) to the tool connector.
SRS006
4. Connect red clip of deployment tool to battery positive termi-
nal and black clip to negative terminal.
5. The lamp on the right side of the tool, marked ªdeployment tool
powerº, should glow green, not red.
6. Press the button on the deployment tool. The left side lamp on
the tool, marked ªair bag connector voltageº, will illuminate and
the air bag module or seat belt pre-tensioner will deploy.
CAUTION:
Activate only one air bag module or seat belt pre-tensioner at
a time.

DISPOSING OF AIR BAG MODULE AND SEAT BELT
PRE-TENSIONER
NJRS0022S04Deployed air bag module and seat belt pre-tensioner are very hot.
Before disposing of air bag module, and seat belt pre-tensioner
wait at least 30 minutes, and 10 minutes, respectively. Seal them
in a plastic bag before disposal.
CAUTION:
+Never apply water to a deployed air bag module and seat
belt pre-tensioner.
+Be sure to wear gloves when handling a deployed air bag
module and seat belt pre-tensioner.
+No poisonous gas is produced upon air bag module
deployment. However, be careful not to inhale gas since it
irritates throat and can cause choking.
+Do not attempt to disassemble air bag module and seat
belt pre-tensioner.
+Air bag module and seat belt pre-tensioner cannot be
reused.
+Wash your hands clean after finishing work.

If no malfunction is detected on ªSELF-DIAG [CURRENT]º even
though malfunction is detected in ªSRS Operation Checkº, check
the battery voltage.
If the battery voltage is less than 9V, charge the battery. Then go
to DIAGNOSTIC PROCEDURE 3, page RS-66.
If the battery voltage is OK, go to DIAGNOSTIC PROCEDURE 4,
page RS-68, to diagnose the following cases:
+Self-diagnostic result ªSELF-DIAG [PAST]º (previously stored
in the memory) might not be erased after repair.
+The SRS system malfunctions intermittently.
Hatchback
If no malfunction is detected on ªSELF-DIAG [CURRENT]º but mal-
function is indicated by the ªAIR BAGº warning lamp, go to DIAG-
NOSTIC PROCEDURE 4, page RS-68, to diagnose the following
situations:
+Self-diagnostic result ªSELF-DIAG [PAST]º (previously stored
in the memory) might not be erased after repair.
+The SRS system malfunctions intermittently.
8. Touch ªPRINTº.
9. Compare diagnostic codes to ªCONSULT-II Diagnostic Code
Chartº, page RS-62 (4-door Sedan) or RS-64 (Hatchback).
10. Touch ªBACKº key of CONSULT-II until ªSELECT SYSTEMº
appears in order to return to User mode from Diagnosis mode.
11. Turn ignition switch ªOFFº, then turn off and disconnect
CONSULT-II, and disconnect both battery cables.
12. Repair the system as outlined by the ªRepair orderº in ªCON-
SULT-II Diagnostic Code Chartº, that corresponds to the self-
diagnostic result. For replacement procedure of component
parts, refer to RS-26.
13. After repairing the system, go to DIAGNOSTIC PROCEDURE
