Trouble DiagnosisNKS002ED

The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-
ence, etc.). Check the symptoms below to diagnose the malfunction.

The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction-
ing. Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and
operation of each piece of electrical equipment, and then determine the cause.

Refer to "SERVICE BULLETIN NTB04-119" for the diagnosis of satellite radio.
NOTE:
Noise resulting 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.
Symptom Possible malfunction location

UP” and “SEEK UP” switches function is
normal. If not, go to 3.
3. Check if remote control signal A circuit
between steering switch and TEL
adapter unit is not open or short.
4. Check voltage of remote control signal A
between steering switch and TEL
adapter unit when operating steering
switch.
Dial the cellular phone. The front speaker
RH does not outputs a dial tone.1. Check TEL ON signal circuit. Go to the
next step if normal.
