PRECAUTION
1. BEFORE WORKING ON FUEL SYSTEM, DISCON-
NECT NEGATIVE (±) TERMINAL CABLE FROM BAT-
TERY
HINT:
Any diagnostic trouble code retained by the ECM will be erased
when the battery negative (±) terminal cable is removed from
the battery.
Therefore, if necessary, read the diagnostic trouble code(s) be-
fore removing the negative (±) terminal cable from the battery.
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME
WHEN WORKING ON FUEL SYSTEM
3. KEEP GASOLINE AWAY FROM RUBBER OR LEATH-
ER PARTS
4. MAINTENANCE PRECAUTIONS
(a) Precaution when the connecting gauge.
Use battery as the power source for the timing light, etc.
(b) In the event of engine misfire, these precautions should
be taken.
(1) Check proper connection of battery terminals, etc.
(2) Handle high±tension cords carefully.
(3) After repair work, check that the ignition coil termi-
nals and all other ignition system lines are recon-
nected securely.
(4) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.
(c) Precautions when the handling heated oxygen sensors.
(1) Do not allow oxygen sensor to drop or hit against an
object.
(2) Do not allow the sensor to come into contact with
water.
5. IF VEHICLE IS EQUIPPED WITH MOBILE RADIO SYS-
TEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communication system,
refer to the precaution in the IN section.
6. AIR INDUCTION SYSTEM
(a) Separation of the engine oil dipstick, oil filler cap, PCV
hose, etc. may cause the engine to run out of tune.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will cause air suction and cause the engine to run
out of tune.
