2. 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.
3. 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.

Vehicles with power antennas may exhibit audible electrical noise on weak AM stations when
various electrical accessories (turn signals, rear defogger, cruise control, brakes, etc.) are operated.
Poor antenna grounding can cause this condition.
To eliminate or reduce the intensity of the noise, use the following repair procedure:
AM STATIC NOISE ON VEHICLES WITH POWER ANTENNASPage 1 of 2
OCTOBER 25, 1996
AUDIO
AU002±96
ALL MODELS
REPAIR PROCEDURE:
1. Tune the radio to a strong, static±free AM
station and slowly move the tip of the
antenna mast forward and back
approximately 2 inches (Fig. 1). If static
noise is not heard, go to Step 2. If static
noise is heard during antenna movement,
replace the antenna mast and go to Step 3.

NOTE:Do not touch the antenna mast with
your bare hands. Use a glove or
nonmetallic object to move the
antenna. (If you touch the antenna
with your hands, you will change the
antenna sensitivity).
2. Remove the antenna mast and inspect the
base of the mast for corrosion and damage
(Fig. 2). Clean with 1500 grit sandpaper.
3. Remove the antenna assembly and inspect
the inner fender around the antenna hole
for corrosion (Fig. 3). Clean with 1500 grit
sandpaper.
