Diagnostic procedures
When starting inspection, please first use the specially designed diagnostic instrument (X - 431 diagnostic scanner)
and the ECU to diagnose the communication and determine the causes of malfunction. If communication fails,
please perform the following inspections
StepsInspection Operation
1
Examine the battery
• Check the battery voltage
• Is the voltage higher than 9 V?
Examine the charging/discharging system, and then go to step
5
YesGo to the next step
NoBattery power supply
is insufficient
2
Examine the conducting state of the wire harness between the
ECU unit and combination meter
• Set the ignition switch to the LOCK position
• Disconnect the battery's negative terminal
• Open the dashboard base
• Disconnect the instrument cluster connectors
• Connect the battery's negative
• Set the ignition switch to the ON position

General Instructions and Operations of Seat Belt
Front seat belt warning:
The front seat belts are equipped with seat belt indicator. The driver seat belt indicator is located on the dash-
board and that of the front passenger is on the air conditioner panel. If the ignition switch is on but the front pas-
senger does not fasten the seatbelts, the indicator will turn on.
Preload three-point type belt retractor:
The front seat belts utilize preload three-point type belt retractors. The preload three-point type belt retractor is
loose, enabling the passenger to move freely unless there is an emergency, such as emergency braking, hard ac-
celeration, or hard turning.
Operation notice and function examination:
Areas of Importance
If the seat belt retractor is installed incorrectly, the seat belt will lose its function in the event of an accident, and
thus fail to protect the passenger!
Prevent sharp and harmful substances from touching the seat belt.
Avoid winding or breaking the seat belt lock tongue and seat belt lock bu\
tton.
Do not bleach or dye the seat belt woren band. Wash it with neutral liquid soap and water only.
Before installing the seat belt mounting bolt, manually tighten the seat\
belt bolts to avoid improper clipping.
Do not repair the seat belt retractor or seat belt lock button. If the seat belt is broken, the seat belt assembly must
be replaced.
Change the broken or damaged seat belt.
Function examination:
1. Check whether all the seat belt mounting bolts are tightened.
2. Check the seat belt lock button. The lock button should be unlocked and able to lock easily.
3. After locking the seat belt, the seat belt lock tongue can no longer loo\
sen.
4. Pull all the seat belts out. Seat belts cannot have knots or tears.
5. The belt should retract smoothly but not roughly.
Warning:
Different metals making direct contact will accelerate corrosion. Make sure to use the correct fastening
piece to avoid premature corrosion!
4. Install the seat belt lower mounting bolt.

(cannot be manually moved).
Adjust the parallel operation condition
Instructions: Only when the sunroof is on the initial position,
and the drive device and window panel are removed, can the
parallel operation conditions be adjusted.
