DIAGNOSIS

Required Special Tool:

• MB991223: Harness set

STEP 1. Measure at radio and CD player or radio, CD 
player and CD changer connector C-111 in order to check 
the power supply circuit to the radio and CD player or 
radio, CD player and CD changer (through the battery).
(1) Disconnect radio and CD player or radio, CD player and CD 

changer connector C-111, and measure at the wiring 
harness side.

(2) Measure the voltage between terminal number 11 and 

ground.

• The voltage should measure approximately 12 volts 

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : Either repair or replace the radio and CD player or 

radio, CD player and CD changer. Check that a 
memory is retained.

NO :  Go to Step 2.

STEP 2. 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: Is radio and CD player or radio, CD player and CD 

changer connector C-111 in good condition?
YES : Go to Step 3.
NO :  Repair or replace the component(s). Refer to GROUP 

00E, Harness Connector Inspection 

P.00E-2

. Check 

that a memory is retained.

STEP 3. Check the wiring harness between radio and CD 
player or radio, CD player and CD changer connector 
C-111 (terminal 11) and the battery.

NOTE: Also check intermediate connector C-29 and joint con-
nector(1) C-01 for loose, corroded, or damaged terminals, or 
terminals pushed back in the connector. If intermediate connec-
tors C-29 or joint connector(1) C-01 is damaged, repair or 
replace the connector as described in GROUP 00E, Harness 
Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between radio and CD player or 

radio, CD player and CD changer connector C-111 
(terminal 11) and the battery in good condition?
YES : Repair or replace the radio and CD player or radio, 

CD player and CD changer. Check that a memory is 
retained.

NO :  Repair the wiring harness. Check that a memory is 

retained.

INSPECTION PROCEDURE 23: CD can not be Inserted.

DIAGNOSIS

STEP 1. Check that a CD has been already loaded.
Q: Has a CD been already loaded?

YES : Take out the CD (If the CD can not be ejected, refer to 

INSPECTION PROCEDURE 27 

P.54A-213

). Check 

that a CD can be inserted.

NO :  Go to Step 2.

STEP 2. Check how a CD is inserted.
Ensure that the ignition switch is at 'ACC' or 'ON'.
NOTE: If you try to load a CD when the ignition switch is at the 
positions other than 'ACC' or 'ON,' the CD will not be inserted 
completely and then rejected.
Q: If you try to load the CD, does the CD stops halfway and 

then rejected?
YES : Refer to INSPECTION PROCEDURE 27 

P.54A-213

.

NO :  Go to Step 3.

STEP 3. Check after the CD is loaded.
NOTE: Even though the CD is loaded, 'E01' [vehicles with 
multi-center display (low grade type)] or 'ERROR 01' [vehicles 
with multi-center display (middle grade type)] sometimes dis-
played with the CD rejected because of vibration/shock or dew 
on the CD face or optical lens.
Q: Though the CD is inserted completely, is 'E01' [vehicles 

with multi-center display (low grade type)] or 'ERROR 
01' [vehicles with multi-center display (middle grade 
type)] displayed and the CD ejected?
YES : Go to Step 4.
NO :  There is no action to be taken.

STEP 4. Check the CD.
Check the CD for the conditions below:

• Is the CD loaded with its label facing down?

• Is the recorded face dirty or scratched?

• Is there dew on the recorded face?

Q: Is the CD in good condition?

YES : Go to Step 5.
NO :  The original CD is defective. Check that a CD can be 

inserted.
