STEP 1. Using scan tool MB991958, read the ETACS-ECU
diagnostic trouble code
Check if DTC is set to the ETACS-ECU.

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 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 : Troubleshoot the ETACS-ECU. (Refer to

P.54A-732

.)

NO : Go to Step 2.

STEP 2. Using scan tool MB991958, diagnose the CAN bus
line.
(1) Turn the ignition switch to the "ON" position.
(2) Diagnose the CAN bus line.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?

YES : Go to Step 3.
NO : Repair the CAN bus line. (Refer to GROUP 54C,

Diagnosis

P.54C-17

).

STEP 3. Combination meter operation check
Check that the combination meter works normally.
Q: Is the check result normal?

YES : Go to Step 4.
NO : Check the power supply circuit of combination meter.

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 combination meter.
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

).

DTC U0019: Bus off(CAN-B)

CAUTION

• If DTC U0019 is set, be sure to diagnose the

CAN bus line.

• When replacing the ECU, always check that

the communication circuit is normal.

.

DIAGNOSTIC FUNCTION

If the CAN-B circuit malfunction occurs, the combina-
tion meter sets DTC U0019.

.

JUDGMENT CRITERIA

With the ignition switch at the ON position and the
system voltage at 10

− 16 volts (data from

ETACS-ECU), if the combination meter becomes
unable to transmit data normally due to the CAN-B
bus circuit malfunction, the combination meter deter-
mines that a problem has occurred.

.

TROUBLESHOOTING HINTS

The CAN bus line 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)

DTC U0100: Engine control module CAN timeout

CAUTION

• If DTC U0100 is set, be sure to diagnose the

CAN bus line.

• When replacing the ECU, always check that

the communication circuit is normal.

.

DIAGNOSTIC FUNCTION

The combination meter sets DTC U0100 when it can-
not receive "CHECK ENGINE" signals from the
engine control module.

.

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 engine control module can-
not be established for 600 ms or more, the combina-
tion meter determines that a problem has occurred.
