Display item list
NOTE:
*
: Total elapsed time can be stored up to
65,534 minutes (45.5 days). The display of M.U.T.-III
is fixed to 65,534 minutes after 65,534 minutes have
elapsed. Or, if the battery is disconnected, the total
elapsed time cannot be measured properly. Thus,
65,535 minutes (null value) is displayed. Because it
is calculated based on the ETACS-ECU information,
the correct display may not be shown if the ETACS-
ECU has had a timeout.

NOTE:
*
: If diagnosis codes No. U0331, B1761,
B2206, B2215, or B222C is set, there may be an
error with the coding data stored in the ETACS-ECU.
DIAGNOSIS CODE PROCEDURES
Code No.U0001 Bus error (CAN-C)
Code No.U0019 Bus off (CAN-B)
CAUTION
• If the diagnosis code No. 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 diagnosis code No. U0001
(CAN-C) or U0019 (CAN-B) is stored.
COMMENTS ON TROUBLE SYMPTOM
The ETACS-ECU may have a malfunction, or the
ETACS-ECU power supply or earth circuit may have
a problem.
PROBABLE CAUSES
• Malfunction of the ETACS-ECU
• Malfunction of wiring harness or connector
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-III CAN bus diagnostics
Use the M.U.T.-III to diagnose the CAN bus lines.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Repair the CAN bus line (Refer to GROUP
54C
− Troubleshooting ).
STEP 2. Check whether the diagnosis code is
reset.
Check again if the diagnosis code is set to the
ETACS-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from "LOCK" (OFF)
position to "ON" position.
(3) Check if diagnosis code is set.
Q: Is the diagnosis code set?
YES :
Replace the ETACS-ECU.
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 ).
Code No.U0100 Engine CAN timeout
CAUTION
• If diagnosis code No. U0100 is set to the
ETACS-ECU, always diagnose the CAN bus
line.
• Before replacing the ECU, ensure that the
communication circuit is normal.
DIAGNOSTIC FUNCTION
If the signal from engine ECU cannot be received,
the ETACS-ECU sets the diagnosis code No. U0100.
JUDGEMENT CRITERIA
After the following statuses continue to be true for 5
seconds, if the communication with the engine ECU
cannot be established for 600 ms 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 or more.
• ETACS-ECU system voltage is at 10−16 V.
PROBABLE CAUSES
• Malfunction of engine ECU

DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-III CAN bus diagnostics
Use the M.U.T.-III to diagnose the CAN bus lines.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Repair the CAN bus line (Refer to GROUP
54C
− Troubleshooting ).
STEP 2. M.U.T.-III other system diagnosis code
Check if diagnosis code is set to the engine-ECU.
Q: Is the diagnosis code set?
YES :
Troubleshoot the engine (Refer to GROUP
13A
− Troubleshooting <1600> or GROUP
13B
− Troubleshooting <1800-PETROL-
DOHC, 2000> or GROUP 13C
−
Troubleshooting <DIESEL> or GROUP 13F
− Troubleshooting <1800-SOHC>).
NO :
Go to Step 3.
STEP 3. M.U.T.-III other system diagnosis code
Check if diagnosis code No. U0100 is set to the
ASC-ECU.
Q: Is the diagnosis code set?
YES :
Go to Step 4.
NO :
Go to Step 5.
STEP 4. Check whether the diagnosis code is
reset.
Check again if the diagnosis code is set to the
ETACS-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from "LOCK" (OFF)
position to "ON" position.
(3) Check if diagnosis code is set.
Q: Is the diagnosis code set?
YES :
Replace the engine ECU.
NO :
The trouble can be an intermittent
malfunction such as a poor connection or
open circuit in the CAN bus lines between
the engine ECU and the ETACS-ECU
(GROUP 00
− How to use Troubleshooting/
inspection Service Points
− How to Cope
with Intermittent Malfunction ).
STEP 5. Check whether the diagnosis code is
reset.
Check again if the diagnosis code is set to the
ETACS-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from "LOCK" (OFF)
position to "ON" position.
(3) Check if diagnosis code is set.
Q: Is the diagnosis code set?
YES :
Replace the ETACS-ECU.
NO :

malfunction such as a poor connection or
open circuit in the CAN bus lines between
the engine ECU and the ETACS-ECU
(GROUP 00

Code No.U0101 CVT/AT CAN timeout
CAUTION
• If diagnosis code No. U0101 is set to the
ETACS-ECU, always diagnose the CAN bus
line.
• Before replacing the ECU, ensure that the
communication circuit is normal.
DIAGNOSTIC FUNCTION
If the signal from CVT-ECU, A/T-ECU cannot be
received, the ETACS-ECU sets the diagnosis code
No. U0101.
JUDGEMENT CRITERIA
After the following statuses continue to be true for 5
seconds, if the communication with the CVT-ECU, A/
T-ECU cannot be established for 600 ms 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 or more.
• ETACS-ECU system voltage is at 10−16 V.
