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.

Fuel Tank Removal
Special note: When maintenance of the fuel supply
system requires removal of the fuel line, the pressure
of the fuel system should first be released, so as to
avoid the spraying of high-pressure fuel.
1. Pull out the electrical connector of the fuel pump on the
top of the fuel tank.
2. Pull out the quick connectors of fuel filler hose II and
the inlet rigid pipe, as well as desorption hose I and
the desorption rigid pipe. Afterwards, use a cotton cloth
to block the mouthpiece to avoid the spraying of high-
pressure fuel.
3. Remove the fuel filler pipe connecting hose, air pipe,
and air return hose (two attachment clips and one
clamp) at the rear of the fuel tank.
4. Use specified torque of 26±3 N·m to remove the four
bolts and the strengthening cushion.
Fuel Pump and Charcoal Canister Removal
1. Assembly removal
(a) Remove the pipeline connected to the fuel pump.
(b) Clean any accumulated dirt from the flange of the fuel
pump.
(c) Starting diagonally, use a wrench to successively
remove the small bolts on the install panel of the fuel
pump in diagnostic mode.
(d) Pay careful attention not to damage the fuel level
sensor when taking the assembly out from the fuel
tank.
2. Assembly installation
(a) Carefully install the fuel pump and charcoal canister
assembly, as well as the oil level sensor, ensuring they
will not be damaged.
(b) Ensure that the port of the pipeline between the fuel
pump and charcoal canister is correct.
(c) Install the weatherstrip and install panel using specified
torque of 3-4 N·m to tighten the bolts.
Fuel Filter Removal
1. Pull out the two quick connectors which connect to the
fuel filter.
2. Loosen the bolts on the fuel filter mounting bracket in
order to take out the filter. The entire filter should be
replaced.
