7. Pay attention to the "Areas of Importance" below to
avoid damaging any part:
(a) Do not open the cover or case of the ECU (Electronic
Control Unit) unless it's absolutely necessary. (Touching
the pin of the IC (Integrated Circuit) may damage the
IC due to static electricity.)
(b) When unplugging the vacuum hose, make sure to pull
from the end of the hose but not the center.
IncorrectCorrect
(c) To make hose reassembly more convenient, label the
unplugged portions for easier recognition later. After
performing this task, check carefully to make sure the
hose is connected correctly.
(d) Be careful! Do not drop any electrical components (like
sensors or relay connectors). Replace them at once
if they have been dropped onto a hard surface. They
cannot be used for the second time.
(e) When cleaning the engine with a steam, make sure to
properly protect the ignition coil and air filter as to
prevent water from seeping in.
(f) D o n o t f o r c e f u l l y t r y t o c o n n e c t a h o s e i n t o a n
oversized tube while using a vacuum gauge. Instead,
use a stepped connector. If the hose is stretched, it may
lead to leaking.
8. All resistors must be measured at below 20oC room
temperature unless special situations arise. This is
because resistance value measured under higher
temperature may exceed standard requirements, espe-
cially if measured after driving the vehicle. All measures
should be taken after the engine has cooled down.
Circuit Maintenance Instructions
1. Rules to be obeyed before a circuit is repaired:
(a) Make sure to disconnect the negative (-) cable from the
battery before electrical maintenance is performed.
(b) W h e n i n s p e c t i o n a n d m a i n t e n a n c e w o r k r e q u i r e s
disconnecting the battery, make absolutely sure to
disconnect the negative (-) cable of the battery and that
it is connected to the vehicle body as grounding.
(c) To prevent damaging the wiring terminal of the battery,
loosen the cable's fixing nut and lift up the cable, but
do not forcefully twist or press the cable.
(d) When cleaning up the battery's and the cable's connecting
terminals, make sure to use a special rag, and do not use a
file or other rough material to wipe them.
(e) While connecting the connecting terminals of the cable
and battery, loosen the nuts first, then tighten them
after installation. Do not hammer the cable's connecting
terminals into the battery with a hammer.
(f) I f t h e b a t t e r y ' s g r o u n d c a b l e h a s n o t y e t b e e n
disconnected, please do not try to speed charge the
battery, as this could damage the alternator's diode.
(g) Should the battery's ground cable be disconnected,
please do not try to start the engine, as this could
seriously damage the wire.
(h) Make sure to properly cover the battery's positive (+)
end cover.

the connection among terminals of the wire harness plug.
Note: The BOSCH ABS8.0 hydraulic pressure unit (integrated into the ECU) is not serviceable. If
damaged, the whole unit must be replaced.

Basic Information on the Electrical System
Electrical system schematics reading instructions
1. Configuration introduction
The GWFLORID comes in three configurations: comfort, luxury and elite. The wire harness has two types of
configurations: One is a non jam protection comfort model, which is a combination of both comfort and luxury
type, the other type is called elite. These two configurations are universally used in most of this manual. The
parts that are only available for the non jam protection comfort type have been marked in this manual, please
pay attention to these sections while performing maintenance.
2. Fuse box and power supply introduction
The fuse box located inside the left side of the dashboard is No. 1 Fuse Box, the other one inside the left side of
the engine compartment is No. 2 Fuse Box.
• 30 represents a power cord for normal power, which is from the battery positive fuse box-60 A.
• 30a represents a power cord for normal power, which is from the battery positive fuse box-120 A.
• 30b represents a power cord for normal power, which is from the battery positive fuse box-120 A.
• 15 represents a power cord for small capacity electronics. When the ignition switch is at the "ON" position,
power is supplied by relay IG.
• 15a represents a power cord for small capacity electronics. When the ignition switch is at the "ON"
position, power is directly supplied by ignition switch IG1.
• 15b represents a power cord for small capacity electronics. When the ignition switch is at the "ON"
position, power is directly supplied by ignition switch IG2.
• X represents a power cord for small capacity electronics. When the ignition switch is at the "ACC"
position, power is supplied by relay ACC.

Areas of importance in circuit maintenance
1. Before operating any electronic devices, and when tools or maintenance devices may easily make
contact with an uncovered electronic terminal, please make sure to turn the ignition switch to the LOCK
position, and then disconnect the battery's negative cable to avoid injury or vehicle damage. When the
ignition switch is on the ON position, please do not disconnect the battery's connecting wire or take out
the power's fuse, regardless if the engine is running or not.Otherwise it would seriously damage the
ECU and related microelectronic devices such as sensors.
2. When changing the fuse, please make sure that the new fuse possesses the proper current rating,
and is not above or below this rating.
3. When repairing the wire harnesses of the airbag and pretensioner, only specified contact points,
plugs, and wires are allowed to be used.
4. Before repairing the wire harness, make sure to eliminate any factor that might cause damage,
for example, the edge of a vehicle body part is too sharp, or the used electronics are damaged or
corroded.
5. Shielded wire should not be repaired, it must be replaced entirely once it is damaged.
6. Unless it is specified during the test, please do not use an analog multimeter to test the ECU and
sensor, instead use a high-impedance digital multimeter (internal resistance should be ≥10 kΩ) or a
vehicle multimeter for inspection.
7. When inspecting the connector with a digital multimeter, take the waterproof rubber cover off the
connector, and tightly insert the test pen along the connecting terminal. Don't use too much force, as
to avoid cracking the connector.
Circuit inspection steps
The principle of troubleshooting is to confirm the "possible cause". Once the possible cause is confirmed, the
components that need to be inspected are limited to the components that are related to the possible cause. The
confirmed possible cause should be based on theory and be supported by facts, but not just by intuition. If
one tries to solve the problem but does not adopt the proper troubleshooting steps, it may make the problem
worse. Then the possible cause not only can't be confirmed, but also maintenance can't be performed properly.
Troubleshooting should adhere to the four steps below:
1. Observe the symptoms carefully, inspect if there is anything else abnormal, and record it.
2. While confirming the possible causes, study the circuit diagram carefully, and regard it as a whole
system in order to understand the circuit. Thorough knowledge of switches, relays, and other
electronic components is obligatory for proper analysis.
3. Inspect and eliminate the problems one by one until the cause is found.
4. After the malfunction is fixed, make sure to check if the inspected system is working properly, and also
check if the maintenance may have caused any new problems.
