STEERING SWITCH SIGNAL GND CIRCUIT
DescriptionINFOID:0000000003765600
Transmits the steering switch signal to audio unit.
Diagnosis ProcedureINFOID:0000000003765601
1.CHECK STEERING SWITCH SIGNAL GND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect audio unit connector and spiral cable connector.
3. Check continuity between audio unit harness connector and spiral cable harness connector.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK SPIRAL CABLE
Check spiral cable.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace spiral cable.
3.CHECK GROUND CIRCUIT
1. Connect audio unit connector.
2. Check continuity between audio unit harness connector and ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Replace audio unit.
4.CHECK STEERING SWITCH
1. Turn ignition switch OFF.
2. Check steering switch. Refer to AV-25, "
Component Inspection".
Is the inspection result normal?

NOTE:
 Audio operation information, refer to Owner's Manual.
 The majority of the audio concerns are the result of outside causes (bad CD, electromagnetic interference,
etc.).
NOISE
The following noise results from variations in field strength, such as fading noise and multi-path noise, or
external noise from trains and other sources. It is not a malfunction.
 Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-
tains or buildings blocking the signal.
 Multi-path noise: This noise results from the waves sent directly from the broadcast station arriving at the
antenna at a different time from the waves that reflect off mountains or buildings.
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and then determine the cause.
NOTE:
The source of the noise can be easily found by listening to the noise while removing the fuses of electrical
components, one by one.
Types of Noise and Possible Causes
Occurrence condition Possible cause
Occurs only when engine is ON.A continuous growling noise occurs. The speed of
the noise varies with changes in the engine speed. Ignition components
The occurrence of the noise is linked with the operation of the fuel pump.  Fuel pump condenser
Noise only occurs when various
electrical components are oper-
ating.A cracking or snapping sound occurs with the op-
eration of various switches. Relay malfunction, audio unit malfunction
The noise occurs when various motors are operat-
ing. Motor case ground
Motor
The noise occurs constantly, not just under certain conditions. Rear defogger coil malfunction
 Open circuit in printed heater
 Poor ground of antenna feeder line
A cracking or snapping sound occurs while the vehicle is being driven, especially when
it is vibrating excessively. Ground wire of body parts
 Ground due to improper part installation
 Wiring connections or a short circuit
