INSTALLATION SERVICE POINT
.A(STEERING WHEEL INSTALLATION
To center the clock spring, line up the “NEUTRAL” markof the clock spring with the mating mark.
CautionIf the clock spring’s mating mark is not properly
aligned, the steering wheel may not be completely
rotational during a turn, or the flat cable within the
clock spring may be severed, obstructing normal op-eration of the SRS and possibly leading to serious
injury to the vehicle’s driver.
INSPECTION
(1) Remove the knee protector and the column cover. (Refer
(2)
to GROUP 52A - Instrument Panel.)
Disconnect the column switch left connector (16 terminals)
and check the continuity between the terminals for each
switch.
LIGHTING SWITCH CHECK
Operate the switch and check the continuity between the termi-
nals.

About multipath noise and fading noise
Because the frequency of FM waves is extreme-
ly high, it is highly susceptible to effects from
geological formations and buildings. These ef-
fects disrupt the broadcast signal and obstruct
‘reception in several ways.l Multipath noise
This describes the echo that occurs when the
broadcast signal is reflected by a large obstruc-
tion and enters the receiver with a slight time
delay relative to the direct signal (repetitious
buzzing).l Fading noise
This is a buzzing noise that occurs when the
broadcast beam is disrupted by obstructing ob-
jects and the signal strength fluctuates intricately
within a narrow range.

Noise is often created by the following factors, and
often the radio is OK when it is checked individually.l Traveling conditions of the vehicle
l Terrain of area traveled through

tors listed above as well as determining whetherthe problem occurs with AM or FM, the station
names, frequencies, etc., and contact a service cen-
