RADIO AND CD PLAYER

CHASSIS ELECTRICAL

54A-229

SYMPTOM PROCEDURES

Inspection Procedure 1: Power of the radio and tape player does not turn ON when the ignition switch 
is in the "ACC" position or "ON" position.

CAUTION

Before replacing the radio and CD player, ensure 
that the power supply circuit, the earth circuit 
and the communication circuit are normal.

OPERATION

When the ignition switch is in the ON or ACC posi-
tion, the radio and CD player power can be turned 
ON. With the radio and CD player power ON, when 
the ignition switch is turned to the OFF position, the 
power for radio and CD player is also turned OFF.

COMMENTS ON TROUBLE SYMPTOM

Provided that the audio diagnosis code is not set, if 
the power for radio and CD player cannot be turned 
ON, the radio and CD player, or power supply circuit 
for radio and CD player may have a problem, or the 
option coding information may be inconsistent.

PROBABLE CAUSES

• Malfunction of radio and CD player

• Malfunction of the ETACS-ECU

• Option coding information inconsistency

STEP 7. Check of short to power supply, short to 
earth, and open circuit in +B2 line between 
fusible link and radio and CD player connector

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ).

NO : 

Replace the radio and CD player.

Inspection Procedure 2: No sound is heard.

CAUTION

Before replacing the radio and CD player, ensure 
that the power supply circuit, the earth circuit 
and the communication circuit are normal.

COMMENTS ON TROUBLE SYMPTOM

If the audio sound is not output, the radio and CD 
player may have a problem. In addition, if any of the 
speakers or tweeters is short-circuited, the protection 
circuit inside the radio and CD player disables all the 
speakers or tweeters to sound. Therefore, if all the 
speakers do not output sound, the speaker or 
tweeter circuit may be shorted or the speaker or 
tweeter may be defective.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ).

NO : 

Replace the radio and CD player.

Inspection Procedure 3: The radio broadcasting can not be received.

CAUTION

Before replacing the radio and CD player, ensure 
that the power supply circuit, the earth circuit 
and the communication circuit are normal.

COMMENTS ON TROUBLE SYMPTOM

In case of FM/AM radio broadcasting cannot be 
received., antenna rod, antenna base, antenna 
feeder or radio and CD player may have a problem.

RADIO AND CD PLAYER

CHASSIS ELECTRICAL

54A-232

NOTE: The radio wave may not be received if the 
vehicle is placed in the area which is exposed to a 
special electric field. Thus, check that the radio 
broadcasting can be received using the radio of 
another vehicle before carrying out diagnosis.

PROBABLE CAUSES

• Malfunction of antenna rod

• Malfunction of antenna base

• Malfunction of antenna feeder

• Malfunction of radio and CD player

DIAGNOSIS PROCEDURE

STEP 1. Check the state of the antenna rod and 
antenna base.

Q: Is the antenna assembled?

YES : 

Go to Step 2.

NO : 

Assemble antenna rod and antenna base.

STEP 2. Check to see if inspections are taking 
place is an area exposed to special electric 
fields.

Q: Is the reception area exposed to special electric 

fields?
YES : 

Go to Step 3.

NO : 

Go to Step 4.

STEP 3. Move the vehicle and check the radio.
Move the vehicle to a good reception area that is not 
exposed to special electric fields.

Q: Is the check result normal?

YES : 

Diagnosis complete.

NO : 

Go to Step 4.

STEP 4. Check if there is any damage to the 
antenna rod, antenna base and antenna feeder.

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Replace the antenna rod, antenna base and 
antenna feeder.

STEP 5. Check the connection of the antenna 
feeder’s plug and radio and CD player.

Q: Is the antenna feeder’s plug thoroughly connected 

to the radio and CD player?
YES : 

Go to Step 6.

NO : 

Thoroughly connect the antenna feeder’s 
plug and the radio and CD player.

STEP 6. Check of short or open circuit in ANT+ 
line between radio and CD player connector and 
antenna amplifier connector

Q: Is the check result normal?

YES : 

Go to Step 7.

NO : 

Repair the connector(s) or wiring harness.

STEP 7. Substitute a known good radio and CD 
player, and check the trouble symptom.

Q: Is the check result normal?

YES : 

Replace the radio and CD player.

NO : 

Either repair or replace the antenna rod and 
antenna base.

Inspection Procedure 4: Audio illumination does not work normally.

CAUTION

Before replacing the radio and CD player, ensure 
that the power supply circuit, the earth circuit 
and the communication circuit are normal.

COMMENTS ON TROUBLE SYMPTOM

If the tail lamps illuminate, illumination signal is sent 
from the heater controller assembly (A/C-ECU) to the 
radio and CD player. This switches the illumination of 
the radio and CD player from day mode to night 
mode. If the mode is switched, the illumination signal 
line, the heater controller assembly (A/C-ECU) or the 
radio and CD player may be defective.

PROBABLE CAUSES

• Malfunction of combination meter

• Malfunction of heater controller assembly 

(A/C-ECU)

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

STEP 1. Check that the tail lamps illuminate.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Diagnose the tail lamps. (Refer to 

P.54A-140

.)
