1. Operations prior to Removal
(1) Turn the ignition switch OFF.
(2) Remove negative (-) terminal cable of the battery. Put it in a proper position or wrap it up with insulating
tape.Fig. 4.Fig. 5.5-64SunshadeSRS (Supplemental Restraint System)-SRS-General Information

Notice
1. Work must be started 60s after the negative (-) terminal cable is detached from battery. The detached
negative (-) terminal cable shall be protected with insulating tape for insulation.
2. Never attempt to dismantle or repair an ECU. If there is any trouble, replace the ECU with a new one.
3. Prevent the ECU from shock or vibration. If pitting, crack or distortion is found, replace the ECU with a
new one.
4. Every time an airbag is deployed, the ECU shall be replaced with a new one.
5. When disassembling or maintaining the parts around ECU, attention must be given to avoid contacting the
ECU. 2. Removal procedures:
(1) Remove the miscellaneous box in the middle consoce.
(2) Remove the connectors to SRS ECU.
(3) Remove ECU.
3. Installation procedures:
(1) Install ECU.
(2) Install the connectors to SRS ECU.
(3) Install the miscellaneous box in the middle consoce.
(4) Connect negative (-) terminal cable of the battery.
4. Key points for Installation:
(1) Install ECU.Notice
If the ECU cannot be installed correctly, the airbag will not act normally.
5. Check
a. ECU case for pitting, crack and distortion
b. The connector for damage and distortion.Notice
If pitting, crack or distortion is found on an ECU, replace it with a new one.VII. Airbag assembly & clock spring1.Removal and Installation of driver airbag and clock spring
Operations prior to removal
(1)Take out the ignition key after the steering wheel and front
wheel are adjusted to straightforward direction.
(2)Remove negative (-) terminal cable from the battery.
Removal procedures of the driver airbag assembly:
(1) Unscrew the screws of the two sides, see fig.15-65SRS (Supplemental Restraint System)-SRS-General Information (2) Check after installation.
a. Turn the ignition switch ON.
b. The warning light goes on within 4s, and then goes out.
(3) If the light doesn't go out, check the trouble and eliminate it.
For other ECU inspections, see Troubleshooting.
fig.1

5-67Notice
When connecting or disconnecting the turn the ignition switch OFF first.
d. Turn the ignition switch ON.
e. Read the diagnostic circuit and see if the other locations than the troubled area of the airbag are normal.
f. Turn the ignition switch OFF.
g. Remove the negative (-) terminal cable from the battery, and protect it with insulating tape for insulation.Notice
Work must be started 60s after the negative (-) terminal cable is disconnected from battery.
(2) Installation of clock spring
Screw up the clock spring clockwise to the end, rotate it counter-
clockwise by 2.5 turns, and align it with the mark (see the figure 3).Notice
If the center of the clock spring cannot be aligned, the steering
wheel will not turn midway, or cause bad performance to the clock
spring circuit, consequently hamper the normal action of the airbag.
(3) Installation of the components of the steering wheel and airbag assembly
a. When the center of the clock spring is aligned, install the components of the steering wheel and airbag
assembly.
b. After being installed, rotate the left and right sides of the steering wheel to position, and make sure there
is no abnormality.
(4) Check after installation
a. Slightly rotate the steering wheel left and right, make sure that there is no abnormality or noise. (Driver
airbag module, clock spring)
b. Turn the ignition switch ON.
c. The warning light goes on within 4s, and then goes out.figure 3SRS (Supplemental Restraint System)-
SRS-General Information b. Connect negative (-) terminal cable of the battery.
c. Connect the diagnostic connector (16 pins).Notice
In case of scrapping an airbag, it shall be noted that the airbag shall be deployed according to the specified
procedures before being scrapped.SRS Air Bag
Warning LightNotice
When installing the components of the steering wheel and
airbag assembly, attention should be given to protect the wire
harness of the clock spring from seizure.
d. The trouble shall be eliminated if the warning light remains on when the ignition switch is turned on or
after it goes out after 4s.

5-73Precautions:1. Don't operate refrigerant in confined space or near open fire.
2. Always wear eyeglass.
3. Be careful don't let liquid refrigerant contact your eyes and skin,
if liquid refrigerant contacts your eye or skin.
(a) Please wash with fresh water.
Warning:
Don't knead your eyes or scrub your skin
(b) Apply soft petroleum ointment on your skin.
(c) See doctor or go to hospital immediately for specialized
treatment.
4. Don't heat container or put it near open fire.
5. Be careful not to fall off, object should not touch container.
6. If there is no sufficient refrigerant in refrigerating system, don't
operate the compressor.
If there is no sufficient refrigerant in the system, insufficient oil
lubrication might cause burning out of compressor. Be careful to
avoid occurrence of such things.
7. When compressor runs, don't turn on pressure gauge high-pressure
valve.
If high-pressure valve is turned on, refrigerant will flow in reverse
direction, and cause bursting of refrigerant tank, so only low
pressure valve may be turned on or off.
8. Be careful to avoid excess refrigerant
Excess refrigerant will result in poor refrigerating capacity, worse
fuel economical efficiency, engine overheat etc problems.Symptom

fault code, display no fault code. Now, press OK key to turn page, look down for fault code and its description.
There is generally P or O before fault code, which represents that this is a persistent fault or a occasional fault.
Persistent fault always exists, while occasional fault may be eliminated, only when run on real vehicle, might it
appear again.
Note:
Read fault code function can not be exited in midway, only after all fault codes are turned over, could it return
to function menu.
Eliminate fault code
2. In function selection function menu 05, press OK key to eliminate fault code, if fault code cannot be eliminated,
it shows that this is a occasional fault, could be detected again only when the vehicle is actually running.IV. Display mode of malfunction codeDisplay code
