2. Inspect output signal of vehicle speed.
(1) When vehicle run at 10km/h, inspect voltage between ter-
minal10 and terminal A1 of combination instrument assembly.
Standards: the voltage pulsates repeatedly between
0V to 5V for thirteen times.
Notes: Inspect the ignition switch “on” connects the
joint
3. Inspect speed gauge
(1) Connect a test tachometer. then startup the engine.
Notes:
zTachometer terminals polarity connects oppositely will damage interior transistors and
LEDs.
zWhen move or disassemble tachometer. do not drop on the ground or knock the surface.
(2) Compare indicted value test tachometer and combination instrument tachometer.
Standard indicted value (rmp) permitted values (rpm)
700 630-770

(1) Disassemble the joint of fuel meter
(2) Turn ignition switch to ON, inspect indictor position of fuel guage.
Indictor position: F
(3) Connect short terminal1 and terminal2 of wiring harness sides. Turn ignition switch to ON, inspect
indictor position of fuel guage.
Indictor position: F
5. Inspect low fuel level indictor 4. Inspect fuel gauge
The fuel gauge has the function of sensor detection (that is
failure treatment of oil level tachometer)that is when fuel gauge
indictor is at E position, if low oil level warning light doesn”t
light, first should judge whether there have open-loop trouble of
fuel sensor or wiring harness. When sensor fails, fuel indictor
should stop at current position. But if failing time is over 20
seconds, the indictor will return to E position quickly, the in-
strument will at wire break detection. If the normal situation of
detection panel is over 20 seconds, indicator will return to normal.

Inspection on automobile
1. Basic inspection for electric door locker.
(a) Press middle control switch to locker closing side, and check the all doors should be locked; then
press middle control switch to locker opening side, and check all doors should be opened.
(b) Insert key in door locker and turn it anticlockwise, and check all doors should be locked; then turn the
key clockwise, and check all doors should be opened.
(c) Check the keeping protection function of the key.
Note: When checking the keeping protection function of the key, it is necessary to open elec-
tric window at the side of driver to prevent its function from losing and lock the key in
automobile.
(1) Insert key in ignition switch.
(2) Open the door, and press middle control switch on the door at the side of driver to locker closing
side, at this time, door locker could not close.
(3) Open the door, and press locker button on the door at the side of driver to locker closing side, at
this time, door locker could not close.
(4) After pressing locker button upwards for over two seconds, and locking driver door; when driver
door is closed and key is not used to lock, check whether all doors could open automatically.

Anti-stealing and door lock--Electronic anti-stealing system
Electronic anti-stealing system
Electronic anti-stealing system consists of anti-stealing controller, anti-stealing loop and transmitter. One
end of loop covers ignition locker core, the other end connects with anti-stealing controller, and the other end
of controller connects with engine ECU, at the same time, transmitter is assembled in key. Memory of
transmitter stores only mark (code) showing the legal identity of automobile owner, transmitter, anti-stealing
controller and electric injection ECU constitutes a multi-layer effective electronic anti-stealing system verified
by password.
If customer key loses, anti-stealing ECU is changed or engine ECU is changed, it is necessary to match
again in repairing station. When automobile leaves the factory, safety password is delivered directly to
owner for keeping with the type of secrecy. If it is necessary to make a new key, change anti-stealing
controller and make other operations, owner should bring the safety password with the automobile to repair
in repairing station. Repairing station should keep repairing (make new key, change anti-stealing controller
and so on) record for inquiring in future.
