STEP 5. Measure at radio and CD player or radio, CD
player and CD changer connector C-111 in order to check
the battery circuit of power supply system to the radio and
CD player or radio, CD player and CD changer (ignition
switch ACC).
(1) Disconnect radio and CD player or radio, CD player and CD
changer connector C-111, and measure at the wiring
harness side.
(2) Turn the ignition switch to "ACC" position.
(3) Measure the voltage between terminal 10 and ground.
• 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 8.
NO : Go to Step 6.
STEP 6. Check radio and CD player or radio, CD player and
CD changer connector C-111 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q: Are radio and CD player or radio, CD player and CD
changer connector C-111 in good condition?
YES : Go to Step 7.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
. If the power switch is turned on, the radio
and CD player or radio, CD player and CD changer
should operate normally.

STEP 7. Check the wiring harness between radio and CD
player or radio, CD player and CD changer connector
C-111 (terminal 10) and ignition switch (ACC).
NOTE: Also check intermediate connector C-29 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector C-29 is damaged, repair or
replace the connector as described in GROUP 00E, Harness
Connector Inspection
.
Q: Is the wiring harness between radio and CD player or
radio, CD player and CD changer connector C-111
(terminal 10) and ignition switch (ACC) in good
condition?
YES : There is no action to be taken.
NO : Repair the wiring harness. If the power switch is
turned on, the radio and CD player or radio, CD player
and CD changer should operate normally.
STEP 8. Check the installation condition of the radio and
CD player or radio, CD player and CD changer.
NOTE: The radio and CD player or radio, CD player and CD
changer are grounded to the deck crossmember directly.
Q: Are the radio and CD player or radio, CD player and CD
changer installed correctly?
YES : Replace the radio and CD player or radio, CD player
and CD changer. If the power switch is turned on, the
radio and CD player or radio, CD player and CD
changer should operate normally.
NO : Install the radio and CD player or radio, CD player
and CD changer properly. If the power switch is
turned on, the radio and CD player or radio, CD player
and CD changer should operate normally.

CIRCUIT OPERATION
• If the remote controlled radio switch is operated,
the output voltage will change. The radio, CD
player and CD changer operates according to the
change on the voltage. You can switch on/off the
audio unit, control the mode and volume by the
remote controlled radio switch (RH). You can
select a CD track and pre-set radio station, and
tune it by the remote controlled radio switch (LH).
NOTE: You can switch on the audio unit by the
remote controlled switch, but can not switch it off.
.
TECHNICAL DESCRIPTION (COMMENT)
If the system does not recognize the remote con-
trolled radio switches (RH), the clock spring or the
radio, CD player and CD changer may be defective.
.
TROUBLESHOOTING HINTS
• Malfunction of the remote controlled radio switch
(RH)
• Malfunction of the radio, CD player and CD
changer
• Malfunction of the clock spring
• Damaged wiring harness or connectors
DIAGNOSIS
Required Special Tool:
• MB991223: Harness set
STEP 1. Measure the voltage at remote controlled radio
switch power supply circuit at the clock spring connector
C-306.
(1) Disconnect the clock spring connector C-306.
(2) Turn the ignition switch to "ON" position.
(3) Measure the voltage between clock spring connector C-306
(radio, CD player and CD changer side) terminal 2 and
ground.
• The measured value should be approximately 5 volts.
Q: Is the measured voltage approximately 5 volts?
YES : Go to Step 4.
NO : Go to Step 2.
