NO : Repair the CAN bus line. (Refer to GROUP 54C,

Diagnosis

P.54C-17

).

STEP 2. Using scan tool MB991958, read the satellite radio
tuner diagnostic trouble code.

as a poor connection or open circuit in the CAN bus
lines between the satellite radio tuner and the WCM.
(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 WCM.
(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 WCM and register the ID codes. (Refer to

P.42C-10

.)

NO : The trouble can be an intermittent malfunction such

as a poor connection or open circuit in the CAN bus
lines between the satellite radio tuner and the WCM.

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 WCM sets DTC U0245.

.

TROUBLESHOOTING HINTS

• The CAN bus line may be defective.

• The WCM 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: Vehicle 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)

DTC U1412: Implausible vehicle speed signal received

CAUTION

If there is any problem in the CAN bus lines, an incorrect
diagnostic trouble code may be set. Prior to this diagno-
sis, diagnose the CAN bus lines (Refer to GROUP 54C,
Trouble code diagnosis

).

.

TPMS DTC SET CONDITION

WCM receives the wheel speed information from ABS-ECU or
ASC-ECU via the CAN-bus line. If WCM cannot receive the
information about the wheel speed sensor from ABS-ECU or
ASC-ECU, this code is set.

.

TROUBLESHOOTING HINTS

The most likely causes for this DTC to set are:

• Damaged wiring harness and connector

• Malfunction of ABS-ECU or ASC-ECU

• Malfunction of WCM

• Malfunction of ETACS-ECU
