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

(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

* 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.
* Here as long as "return " position appears on the screen, it may finish the testing via "ESC " key and returns

[Description ] when open circuit cannot be detected, there is no signal output
even if vehicle speed reaches above 20 km/h, this fault code
will appear.
[Prompt ] It is probably because that sensor is not mounted, sensor coil or
wiring harness is shorted, air gap between sensor and gear ring is
too large or gear ring is damaged.Possible cause

Sensor is not mounted

Sensor coil or wiring har-
ness is shorted

Air gap between sensor

[Description]When speed >20km/h, if sensor signal exceeds tolerance
range, this fault code will appear.
[Prompt ] It is propably because intermittent poor contact or short
circuit of sensor coil or wiring harness, gear ring is dam
aged or air gap between sensor and gear ring is too large, so
sensor signal is too weak.Possible cause

Intermittent poor contact or
short circuit of sensor coil or
