incorrect  diagnostic  trouble  code  may  be  set.
Prior to this diagnosis, always diagnose the CAN
bus lines.

Before  replacing  the  radio  and  CD  player  or  CD
changer, be sure to check that the power supply
circuit, ground circuit, and communication circuit
are normal.

TROUBLE JUDGMENT
When the vehicle information data is not registered to
the  radio  and  CD  player  or  CD  changer,  the

combination  meter  sets  the  diagnostic  trouble  code
No.U1415.

COMMENTS ON TROUBLE SYMPTOM
The  radio  and  CD  player  or  CD  changer,  ETACS-
ECU, or CAN bus line may have a problem.

PROBABLE CAUSES

｠

Malfunctions of radio and CD player or CD changer

｠

Malfunction of the ETACS-ECU

｠

Malfunction  of  CAN  bus  line  wiring  harness  and
connector

(1)

Connect scan tool MB991958 to the data link connector.

(2)

Turn the ignition switch to "ON" position.

(3)

Diagnose the CAN bus line.

Q:Is the check result normal?

YES:

 Go to Step 2.

 Repair the CAN bus line. (Refer to GROUP 54D,

Diagnosis P.54D-10.) On completion, go to Step 2.

STEP 2. Using scan tool MB991958, read the other system
DTC.
Check if DTC is set to the ETACS-ECU.

Q:Is the DTC set?

YES:

 Diagnose the ETACS-ECU (Refer to GROUP 54Ad, ETACS-

ECU, Diagnosis P.54Ad-8).

NO:

 Go to Step 3.

STEP 3. Recheck for diagnostic trouble code.
Check again if the DTC is set to the radio and CD player or CD
changer.

(1)

Erase the DTC.

(2)

Turn the ignition switch from "LOCK" (OFF) position to "ON"
position.

(3)

Check if the DTC is set.

Q:Is the DTC set?

YES:

 Replace the radio and CD player or CD changer.

NO:

 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).

AUDIO AND NAVIGATION SYSTEM

DIAGNOSIS

Before replacing the radio and CD player or CD changer, be
sure to check that the power supply circuit, ground circuit,
and communication circuit are normal.

TROUBLE JUDGMENT
If the radio and CD player or CD changer continuously apply the
voltage of two volts or more to the speakers for one minute or
more, it is determined that the offset voltage is exceeded, and
then the diagnostic trouble code is set.

COMMENTS ON TROUBLE SYMPTOM
The radio and CD player or CD changer or CAN bus line may
have a problem.

PROBABLE CAUSES

｠

Malfunctions of radio and CD player or CD changer

｠

Malfunction of CAN bus line wiring harness and connector
