lines between the radio and CD player or CD changer
and the combination meter (Refer to GROUP 00, How
to Cope with Intermittent Malfunction

P.00-15

).

DTC U0245: Audio visual navigation unit CAN timeout

CAUTION

• If DTC U0245 is set, be sure to diagnose the

CAN bus line.

• When replacing the ECU, always check that

the communication circuit is normal.

.

DIAGNOSTIC FUNCTION

When the signals from audio visual navigation unit
cannot be received, the combination meter sets DTC
U0245.

.

JUDGMENT CRITERIA

With the ignition switch in the ON position, system
voltage between 10

− 16 volts (data from

ETACS-ECU), power supply fuse (IOD fuse) is OK,
or odometer value is 80.5 km (50 miles) or more, and
the communications with audio visual navigation unit
cannot be established for 2,500 ms or more, the
combination meter determines that a problem has
occurred.

.

TROUBLESHOOTING HINTS

• The CAN bus line may be defective.

• The combination meter may be defective.

• The audio visual navigation unit may be defec-

tive.

DIAGNOSIS

Required Special Tools:

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

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

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A (Vehicles with

CAN communication system)

STEP 1. Using scan tool MB991958, diagnose the CAN bus
line.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to "How to connect the

Scan Tool (M.U.T.-III)

P.54A-31

."

(2) Turn the ignition switch to the "ON" position.
(3) Diagnose the CAN bus line.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?

YES : Go to Step 2.
NO : Repair the CAN bus line. (Refer to GROUP 54C,

Diagnosis

P.54C-17

).

STEP 2. Using scan tool MB991958, read the audio visual
navigation unit diagnostic trouble code.
Check if DTC is set to the audio visual navigation unit.
Q: Is the DTC set?

YES : Troubleshoot the MMCS. (Refer to

P.54A-460

.)

NO : Go to Step 3.

STEP 3. Using scan tool MB991958, read the ETACS
diagnostic trouble code.
Check if the DTC U0245 is set to the ETACS-ECU.
Q: Is the DTC set?

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

STEP 4. Recheck for diagnostic trouble code.
Check again if the DTC is set to the combination meter.
(1) Erase the DTC.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON"

position.

(3) Check if DTC is set.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?

YES : Replace the CAN box unit (audio visual navigation

unit).

NO : The trouble can be an intermittent malfunction such

as a poor connection or open circuit in the CAN bus
lines between the CAN box unit (audio visual
navigation unit) and the combination meter (Refer to
GROUP 00, How to Cope with Intermittent
Malfunction

P.00-15

).

STEP 5. Recheck for diagnostic trouble code.
Check again if the DTC is set to the ETACS-ECU.
(1) Erase the DTC.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON"

position.

(3) Check if DTC is set.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?

DTC U1415: Coding not completed/Data fail

CAUTION

• If DTC U1415 is set, diagnose the CAN bus

lines.

• When replacing the ECU, always check that

the communication circuit is normal.

.

DIAGNOSTIC FUNCTION

If the vehicle information data is not registered to the
combination meter, the combination meter sets DTC
U1415.

.

JUDGMENT CRITERIA

With the global coding counter value "0," if all the glo-
bal coding data (vehicle information) are not stored,
the combination meter determines that a problem
has occurred.

.

TROUBLESHOOTING HINTS

• The CAN bus line may be defective.

• The combination meter may be defective.

• The ETACS-ECU may be defective.
