(1) Disconnect connector from park switch
(2) Turn ignition switch to ON, park brake warning lamp should go out.
(3) Use conductor to short connector terminal to ground, park brake warning lamp should illuminate.
10. Check park switch
(1) Disconnect connector from park switch
(2) Pull up manual brake, check whether its terminal is connected with ground
Pull up manual brake: on
Manual brake release: off
11. Brake fluid level warning lamp
(1) Disconnect connector from brake fluid level sensor
(2) Turn ignition switch to ON, brake fluid level warning lamp should go out.
(3) Use conductor to connect its connector terminal wiring harness terminals directly, brake fluid level
warning lamp should illuminate.
12. Check brake fluid level warning switch
(1) Remove tank cap
(2) Disconnect connector from tank
(3) Check whether terminals are connected.
Floater on top: off
(4) Use sucker to suck out liquid from tank
(5) Check whether terminals are connected.
Floater down: on state
(6) Pour liquid back into tank
13. Rear defrost indicator lamp
(1) Turn ignition switch to ON, and start up engine
(2) Push down defrost switch, now rear defrost indicator lamp should illuminate
(3) Turn ignition switch to OFF, rear defrost indicator lamp should go out
14. Rear foglight indicator lamp
When rear foglight illuminates, rear foglight indicator lamp should illuminate, now A5 terminal should be high
potential.
15. Safety belt warning indicator lamp
(1) Disconnect safety belt switch connector from driver side, now safety belt warning indicator lamp should
go out.
(2) Short connector terminal to ground, safety belt warning indicator lamp should illuminate.Combination Instrument System -Malfunction Symptom Table and Troubleshooting
III. Wiper switch assemblyReplacement
1. Detach steering wheel assembly
(1) Disconnect the main power source of the vehicle.
(2) Remove the passenger SRS module assembly, and cautiously put it in a safe place.
(3) Loosen steering wheel lock-bolts and remove the assembly.
2. Remove wiper switch (1) Disconnect the connector.
(2) Remove the 2 tapping screws that are for mounting the wiper switch, take out the wiper switch from the
bracket of the combination switch.IV. Washer nozzleAdjustment
1. Inspect washer nozzle
(1) Start the engine, check if the position where the washer fluid from the nozzle sprays the windshield is in
the upper center wiped by the blades.
(2) Change the height (left/right) of the nozzle hole to adjust the point where washer fluid sprays the windshield.Wiper and Washer System -Replacement and Adjustment5-25

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
