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.

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.
