STEP 3. Check the ground circuit to the center panel unit.
Measure the resistance at center panel unit connector
C-104.
(1) Disconnect the connector, and measure at the wiring

harness side.

(2) Measure resistance between terminal 9 and ground.

OK: The resistance should be 2 ohm or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 5.
NO : Go to Step 4.

STEP 4. Check the wiring harness between center panel
unit connector C-104 (terminal 9) and ground.

• Check the ground wire for open circuit.

Q: Is the wiring harness between center panel unit

connector C-104 (terminal 9) and ground in good
condition?
YES : Check the trouble symptom.
NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary.

STEP 5. Check the power supply circuit to the center panel
unit. Measure the voltage at center panel unit connector
C-104.
(1) Disconnect the connector, and measure at the harness side

connector.

(2) Measure voltage between terminal 7 and ground.

OK: The voltage should measure approximately 12
volts (battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 7.
NO : Go to Step 6.

STEP 6. Check the wiring harness between center panel
unit connector C-104 (terminal 7) and fusible link (36).

• Check the power supply line for open circuit and short cir-

cuit.

NOTE: Also ETACS-ECU connector C-307, C-317 for loose,
corroded, or damaged terminals, or terminals pushed back in
the connector. If joint connector ETACS-ECU connector C-307,
C-317 are damaged, repair or replace the connector as
described in GROUP 00E, Harness Connector Inspection

.

Q: Is the wiring harness between center panel unit

connector C-104 (terminal 7) and fusible link (36) in
good condition?
YES : Check the trouble symptom.
NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary.

STEP 7. Replace the center panel unit temporarily, and
check the trouble symptom.
Replace the center panel unit temporarily, and check that the
audio works normally.
Q: Is the check result normal?

YES : Replace the center panel unit.
NO : Replace the radio and CD player.

INSPECTION PROCEDURE 5: Audio illuminations does not work normally.

CAUTION

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

.

OPERATION

• When the position light is illuminated, the audio

illumination is switched to the nighttime illumina-
tion.

• When the brightness is adjusted using the combi-

nation meter rheostat switch, the audio illumina-
tion brightness is also adjusted.
