FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER
CAUTION:
If large amount of unburned gasoline flows into the converter, it may overheat and create a fire haz-
ard. To prevent this, observe the following precautions and explain them to your customer.
(a)
Use only unleaded gasoline.
(b)
Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20 minutes.
(c)
Avoid spark jump test.
(1)
Perform spark jump test only when absolutely necessary. Perform this test as rapidly as possible.
(2)
While testing, never race the engine.
(d)
Avoid prolonged engine compression measurement.
Engine compression tests must be done as rapidly as possible.
(e)
Do not run engine when fuel tank is nearly empty.
This may cause the engine to misfire and create an extra load on the converter.
(f)
Avoid coasting with ignition turned off.
(g)
Do not dispose of used catalyst along with parts contaminated with gasoline or oil.

IF VEHICLE IS EQUIPPED WITH MOBILE COMMUNICATION SYSTEM
For vehicles with mobile communication systems such as two-way radios and cellular telephones, observe
the following precautions.
(1)
Install the antenna as far as possible away from the ECU and sensors of the vehicle’s electronic
system.
(2)
Install the antenna feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the ve-
hicle’s electronic systems. For details about ECU and sensors locations, refer to the section on
the applicable component.
(3)
Avoid winding the antenna feeder together with other wiring as much as possible, and also avoid
running the antenna feeder parallel with other wire harnesses.
(4)
Check that the antenna and feeder are correctly adjusted.
(5)
Do not install powerful mobile communications system.

person to drive the vehicle and the other person to operate the OBD II scan tool or hand-held
tester.

When using a 2-wheel drum tester such as a speedometer tester or chassis dynamometer, etc., or
jacking up the rear wheels and driving the wheels, always push in the TRAC cut switch and turn the
TRAC system OFF.
