2. Inspection procedures for related fuses or fuses in re- Inspection procedures for related fuses or fuses in re-Inspection procedures for related fuses or fuses in re-
lay boxes. Inspect the battery for damage, the battery's
charging state, cleanness, and tightening with the
connectors.
Before changing a fuse, make sure to check if the fuse's cur-
rent rating meets the required standards. You must not use a
fuse with a current rate that is higher or lower than required
standards.
Same current rating
3. Binding wire harness connectors.
(a) When disconnecting the connections, first press the two
ends of the connectors together, then loosen the lock
and press the lock pawl to release the connector.
(b) When disconnecting the connector, do not pull on its
wire harness. Grasp the joint directly.
(c) Check if the joint is deformed, damaged, or port lost
before connecting the connector.
(d) The connector is not successfully connected until it
makes a click sound.
4. Wire harness connector inspection.
(a) Check while connecting the connectors.
Squeeze both ends of the connectors to make sure it is com-
pletely plugged in and tightly locked.
(b) Check when disconnecting the connectors.
Check by lightly pulling the wire harness behind the connec-
tor's joint. Look for any unconnected or dropped terminals,
loose clamps, or broken wires.
Visually inspect for instances of corrosion, metal fragments,
oddities, and water, as well as bending, rust, overheating,
pollution or deformed terminals, etc.
(c) Check the contact pressure of the terminals.
Prepare a plug that matches the connector's port, plug it into
the socket, then check for the proper rate of tension after
they are fully engaged.

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.

• Every connector is indicated by its engaging part and
locked on the top.
• Please pull out the connector, insted of its wires.
Note: Before pulling out the connector, please check its
type first.

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.
