CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using scan 
tool.

.

When detecting fault and storing the diagnostic trou-
ble code, the ECU connected to CAN bus line 
obtains the data before the determination of the diag-
nostic trouble code and the data when the diagnostic 
trouble code is determined, and then stores the ECU 
status of that time. By analyzing each data from scan 
tool, the troubleshooting can be performed more effi-
ciently. The displayed items are as the table below.

CAUTION

On troubleshooting, if the ignition switch is 
turned ON while disconnecting connector(s), 
diagnostic trouble code(s) associated with other 
system may be set. On completion, confirm all 
systems for diagnostic trouble code(s). If diag-
nostic trouble code(s) are set, erase them all.

DIAGNOSTIC TROUBLE CODE PROCEDURES

DTC U0019: Bus off (CAN-B)

CAUTION

If there is any problem in the CAN bus lines, an 
incorrect diagnostic trouble code may be set. 
Prior to this diagnosis, always diagnose the CAN 
bus lines.

CAUTION

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

.

TROUBLE JUDGMENT

When the radio and CD player is returned from the 
bus off state, or when the bus error is indicated to the 
radio and CD player state, the DTC U0019 (CAN-B) 
is set.

.

COMMENTS ON TROUBLE SYMPTOM

The radio and CD player, power supply for the radio 
and CD player, ground circuit, or CAN bus line may 
have a problem.

.

PROBABLE CAUSES

• Malfunctions of radio and CD player

• Malfunction of CAN bus line wiring harness and 

connector

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

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-331

."

(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. Check whether the scan tool MB991958 can 
communicate with the radio and CD player.
Q: Is the check result normal?

YES : Erase the diagnostic trouble code. This diagnosis is 

complete.

NO :  Check the power supply circuit of the radio and CD 

player, and repair if necessary.

DTC U0141: ETACS CAN timeout

CAUTION

If DTC U0141 is set, be sure to diagnose the CAN 
bus line.

CAUTION

When replacing the radio and CD player, always 
check that the communication circuit is normal.

.

DIAGNOSTIC FUNCTION

If the signal from ETACS-ECU cannot be received, 
the radio and CD player sets the DTC U0141.

.

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 communication with ETACS-ECU cannot be 
established for 2,500 ms or more, the radio and CD 
player determines that a problem has occurred.

.

TROUBLESHOOTING HINTS

• The CAN bus line may be defective

• The radio and CD player may be defective

• The ETACS-ECU may be defective

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)
