Downloaded from www.Manualslib.com manuals search engine 00-7 Precautions:
Warning for Wheel (with tire) RemovalS7RS0B0000003
WARNING!
When removing any of these wheels installed
with wheel bolts, never remove all wheel
bolts at the same time. Leave at least 1 bolt
for each wheel as it is to prevent wheel from
dropping. When removing this remaining 1
bolt, hold wheel and tire so as not to allow
them to come off.

Warning for Handling Emergency Flat Tire
Repair Kit
S7RS0B0000004
WARNING!
If vehicle is equipped with Emergency Flat
Tire Repair Kit instead of spare tire, be sure
to observe “Precaution for Emergency Flat
Tire Repair Kit in Section 2D” when handling
Emergency Flat Tire Repair Kit and repairing
flat tire.
Otherwise, your health may be ruined or it
will be impossible to repair flat tire.

Precautions for Catalytic ConverterS7RS0B0000005
For vehicles equipped with a catalytic converter, use
only unleaded gasoline and be careful not to let a large
amount of unburned gasoline enter the converter or it
can be damaged.
• Conduct a spark jump test only when necessary, make it as short as possible, and do not open the
throttle.
• Conduct engine compression checks within the shortest possible time.
• Avoid situations which can result in engine misfire (e.g. starting the engine when the fuel tank is nearly
empty.)
Precautions for Installing Mobile
Communication Equipment
S7RS0B0000006
When installing mobile communication equipment such
as CB (Citizens-Band)-radi o or cellular-telephone, be
sure to observe the following precautions.
Failure to follow cautions may adversely affect electronic
control system.
• Keep the antenna as far away as possible from the vehicle’s electronic control unit.
• Keep the antenna feeder more than 20 cm (7.9 in.) away from electronic control unit and its wire
harnesses.
• Do not run the antenna feeder parallel with other wire harnesses.
• Confirm that the antenna and feeder are correctly adjusted.
Precaution for CAN Communication SystemS7RS0B0000007
• The loose (1) in the wire harnesses twist of the CAN lines except around the connector (3) should be within
100 mm (3.9 in.). Refer to the wiring diagram for the
CAN lines discrimination. Excessively-loosed lines
may be influenced by the electric noise.
• Do not connect terminals of the CAN line using a bypass wire (1). Otherwise, the CAN line may be
influenced by the electric noise.

good ECM and recheck.
7 Wire circuit check
1) Turn OFF ignition switch.
2) Detach fuel tank referring to “Fuel Tank Removal and
Installation in Section 1G”.
3) Disconnect connector from fuel pump.
4) Measure resistance between “PNK” wire terminal of fuel pump connector and vehicle body ground.
Is resistance infinity? Go to Step 8. “PNK” wire is shorted to
ground.
8 Fuel pump circuit check
1) Connect service wire between “E23-15” terminal of ECM
connector and vehicle body ground.
2) Turn ON ignition switch, measure voltage between “PNK” terminal at fuel pump connector and vehicle body
ground.
Is voltage 10 – 14 V? Go to Step 9. “PNK” wire is open
circuit.
9 Fuel pump circuit check
1) Turn OFF ignition switch.
2) Measure resistance between “BLK” wire terminal at fuel
pump connector and vehicle body ground.
Is resistance less than 5
Ω? Faulty fuel pump. “BLK” wire is open
circuit.
