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 A/C-ECU and the ETACS-ECU (Refer to 
GROUP 00 

− How to use 

Troubleshooting/inspection Service Points 

− 

How to Cope with Intermittent Malfunction ).

Code No.U0168 KOS/WCM CAN timeout

CAUTION

• If the diagnosis code No. U0168 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 

P.54A-33

.)

DIAGNOSTIC FUNCTION

If the signal from KOS-ECU cannot be received, the 
ETACS-ECU sets the diagnosis code No. U0168.

JUDGEMENT CRITERIA

After the following statuses continue to be true for 5 
seconds, if the communication with the KOS-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.
