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 diagnostic trouble 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

• Malfunctions of radio and CD player

• Malfunction of the ETACS-ECU

• Option coding information inconsistency

• Damaged harness wires and connectors

DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

• MB992006: Extra Fine Probe

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

STEP 1. ETACS-ECU coding data check.
(1) Operate scan tool MB991958 to read the ETACS-ECU

option coding information. (Refer to GROUP 00, Coding List

P.00-44

.)

(2) Check that the "AUDIO" is set to "Present."
Q: Is the check result normal?

YES : Go to Step 2.
NO : Operate scan tool MB991958 to set the option coding

"AUDIO" to "Present," and check the trouble
symptom.

STEP 2. Using scan tool MB991958, read the ETACS-ECU
diagnostic trouble code.
Check if the diagnostic trouble code is set to the ETACS-ECU.
Q: Is the DTC set?

YES : Troubleshoot the ETACS-ECU (Refer to GROUP

54A, ETACS, Diagnosis

P.54A-732

), and then go to

Step 3.

NO : Go to Step 3.

STEP 3. Using scan tool MB991958, check data list.
Check if ETACS-ECU related signal is set.

• Turn the ignition switch to the ON position.

• selector lever is "R" (Reverse) position

OK: Normal condition is displayed.

Q: Is the check result normal?

YES : Go to step 8.
NO : Go to step 4.

STEP 4. Check radio and CD player connector C-16 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is radio and CD player connector C-16 in good

condition?
YES : Go to Step 5.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

.

STEP 5. Check the power supply circuit to the radio and
CD player. Measure the voltage at radio and CD player
connector C-16.
(1) Disconnect the connector, and measure at the wiring

harness-side connector.

(2) Measure the voltage between terminal 30 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.

Item No.

STEP 6. Check the wiring harness between fusible link (36)
and radio and CD player connector C-16 (terminal 30).

• Check the power supply lines (battery power supply) for

open circuit and short circuit.

Q: Is the wiring harness between fusible link (36) and radio

and CD player connector C-16 (terminal 30) in good
condition?
YES : Go to Step 7.
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. Check that the radio and CD player is correctly
grounded
The radio and CD player should be connected to the ground
with an assembling screw.
Q: Is the radio and CD player correctly grounded?

YES : Go to Step 8.
NO : Securely install and ground the radio and CD player.

STEP 8. Retest the system
Check if the radio and CD player power is turned ON.
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

P.00-15

).

NO : Replace the radio and CD player.
