5-209. Check park warning lamp
(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

Chapter 4 Light SystemSection 1 Light System IntroductionI. Composition Light system comprises external illumination and signal system and internal illumination system.
The function of the external illumination and signal system is to illuminate the road ahead and send signals
to other vehicles.
The internal illumination system provides internal illumination for driver and passengers.II. Precaution for service1. Precaution when repairing electrical equipments
Disconnect the battery ground cable.
2. Precaution when replacing a headlamp bulb
(1) Before replacing a halogen bulb, turn the headlamp OFF to make it cool.
(2) When installing a new halogen bulb, do not touch the glass part of the bulb with bare hands.
(3) If there is oil stain on the surface of halogen bulb (headlamp and front fog lamp) when the lamps are
turned ON, its service life will be shortened.
(4) Halogen bulbs (headlamp and front fog lamp) have pressurized gas inside and require special handling.
They can explode if dropped to ground. The glass fragments will splash up.
(5) When replacing, make sure to use the bulbs with the same power, same model.
(6) After the bulb is installed, make the lamp holder tight.III. Bulb specificationsRemark: All bulbs are made by Philips Corp..Light System-

* Perform testing of the above steps 2-8 for each wheel. Sequence is as follows: left front right front left
rear right back.
* If result of one of the above steps is different from the result in normal condition, it shows that corresponding
actuator fails to work normally, please check corresponding actuator.

[Description] Firstly visually check whether there is external leakage or
mechanical failure. Use exhaust method to check whether
there is air in the system. Use fault diagnosis instrument
hydraulic pressure unit functional testing to check whether
normally closed valve leaks.Possible cause

Brake fluid leaks

There is air in the system

Brake disc is worn severely

Brake fluid level switch

[Description] Use traditional method to check travel of booster and brake pedal.
Fault of normally open valve may be checked using fault diagnosis
