DIAGNOSTIC TROUBLE CODE PROCEDURES

DTC U0001: Bus off (CAN-C)

DTC U0019: Bus off (CAN-B)

CAUTION

• If DTC U0001 or U0019 is set to the

ETACS-ECU, always diagnose the CAN bus
line.

• Before replacing the ECU, ensure that the

communication circuit is normal.

TROUBLE JUDGMENT

When the ETACS-ECU is returned from the bus off
state, or when the bus off error is indicated to the
ETACS-ECU state, the DTC U0001 (CAN-C) or
U0019 (CAN-B) is stored.

TECHNICAL DESCRIPTION (COMMENT)

The ETACS-ECU may have a malfunction, or the
ETACS-ECU power supply or ground circuit may
have a problem.

TROUBLESHOOTING HINTS

• The ETACS-ECU may be defective.

• The wiring harness or connectors may have

loose, corroded, or damaged terminals, or termi-
nals pushed back in the 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 (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-730

(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,

STEP 2. 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?

YES : Replace the ETACS-ECU.
NO : The trouble can be an intermittent malfunction (Refer

to GROUP 00, How to Cope with Intermittent
Malfunction

P.00-15

DTC U0100: Engine control module CAN timeout

CAUTION

• If DTC U0100 is set to the ETACS-ECU, always

diagnose the CAN bus line.

• Before replacing the ECU, ensure that the

communication circuit is normal.

TROUBLE JUDGMENT

If the signal from engine control module cannot be
received, the ETACS-ECU sets DTC U0100.

JUDGMENT CRITERIA

After the following statuses continue to be true for 5
seconds, if the communication with the engine con-
trol module cannot be established for 0.6 second or
more, the ETACS-ECU determines that a problem
has occurred.

• No abnormality is present to the network.

• Ignition switch is in the ON position.

• No abnormality is present to the power supply

fuse (IOD fuse), or the odometer value is at 80.5
km (50.0 miles) or more.

• ETACS-ECU system voltage is at 10−16 volts.

TROUBLESHOOTING HINTS

• The Engine control module may be defective.

• The ETACS-ECU may be defective.

• The CAN bus may be defective.

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)
