2. FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER
CAUTION:
If large amount of unburned compressed neutral gas (CNG) flows into the converter, it may overheat
and create a fire hazard. To prevent this, observe the following precautions and explain them to your
customer.
(a) Use only unleaded compressed neutral gas (CNG).
(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 neutral gas 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

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.

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.
