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 CAN box unit (MMCS).
NO :
The trouble can be an intermittent
malfunction such as a poor connection or
open circuit in the CAN bus lines between
the CAN box unit (MMCS) and the
ETACS-ECU (Refer to 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 :
The trouble can be an intermittent
malfunction such as a poor connection or
open circuit in the CAN bus lines between
the CAN box unit (MMCS) and the
ETACS-ECU (Refer to GROUP 00
− How to

Code No.U1000 OSS CAN timeout
CAUTION
• If the diagnosis code No. U1000 is set to the
ETACS-ECU, always diagnose the CAN bus
line.
• Before replacing the ECU, ensure that the
power supply circuit, the earth circuit and the
communication circuit are normal.
• When the ETACS-ECU of vehicles without
KOS is replaced, the encrypted code of the
ignition key needs to be registered to the
ETACS-ECU. (If the encrypted code is not reg-
istered, the engine cannot be started. Regis-
ter the encrypted code as described in
Immobilizer System
− How to Register Key ID
DIAGNOSTIC FUNCTION
If the signal from OSS-ECU cannot be received, the
ETACS-ECU sets the diagnosis code No. U1000.
JUDGEMENT CRITERIA
After the following statuses continue to be true for 5
seconds, if the communication with the OSS-ECU
cannot be established for 2,500 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 the OSS-ECU
• Malfunction of the ETACS-ECU
• Damaged harness wires and connectors
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 OSS-ECU.
Q: Is the diagnosis code set?
YES :
Troubleshoot the OSS. Refer to GROUP
42B
− Troubleshooting .
NO :
Go to Step 3.
STEP 3. M.U.T.-III other system diagnosis code
Check if the diagnosis code No. U1000 is set to the
KOS-ECU.
Q: Is the diagnosis code set?
YES :
Go to Step 4.
NO :
Go to Step 5.
