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 ). Repair the CAN
bus line and go to Step 6.
STEP 2. M.U.T.-III other system diagnosis code
Check if diagnosis code is set to the A/C-ECU.
Q: Is the diagnosis code set?
YES :
Troubleshoot the A/C-ECU (Refer to
GROUP 55B
− Troubleshooting ).
NO :
Go to Step 3.
STEP 3. M.U.T.-III other system diagnosis code
Check if a diagnosis code, which relates to CAN
communication-linked systems below, is set.
ETACS-ECU
• Code No. U0164: A/C CAN timeout/Not
equipped
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.
Recheck if the diagnosis code is set.
(1) Erase the diagnosis code.
(2) Turn the ignition switch to "ON" position.
(3) On completion, check that the diagnosis code is
not reset.
Q: Is the diagnosis code set?
YES :
Replace A/C-ECU and then go to Step 6.
NO :
A poor connection, open circuit or other
intermittent malfunction is present in the
CAN bus lines between the A/C-ECU and
the combination meter (Refer to GROUP 00
− How to use troubleshooting/Inspection
Service Points ).
STEP 5. Check whether the diagnosis code is
reset.
Recheck if the diagnosis code is set.
(1) Erase the diagnosis code.
(2) Turn the ignition switch to "ON" position.
(3) On completion, check that the diagnosis code is
not reset.
Q: Is the diagnosis code set?
YES :
Replace combination meter and then go to
Step 6.
NO :
A poor connection, open circuit or other
intermittent malfunction is present in the
CAN bus lines between the A/C-ECU and
the combination meter (Refer to GROUP 00
− How to use troubleshooting/Inspection
Service Points ).
STEP 6. Check whether the diagnosis code is
reset.
Recheck if the diagnosis code is set.
(1) Erase the diagnosis code.
(2) Turn the ignition switch to "ON" position.
(3) On completion, check that the diagnosis code is
not reset.
Q: Is the diagnosis code set?
YES :
Go to Step 1.
NO :
The procedure is complete.
Code No.U0168 WCM/KOS CAN timeout
CAUTION
• If diagnosis code No. U0168 is set, be sure to
diagnose the CAN bus line.
• Before replacing the ECU or combination
meter, ensure that the power supply circuit,
the earth circuit and the communication cir-
cuit are normal.
DIAGNOSTIC FUNCTION
If the signal from KOS-ECU cannot be received, the
combination meter sets the diagnosis code No.
U0168.
JUDGEMENT CRITERIA
With the ignition switch is at ON position, the diagno-
sis code No. U1190 is not stored and the diagnosis
code No. U1195 is not stored, if the communication
with KOS-ECU cannot be established for 2500 ms or
more, the combination meter determines that a prob-
lem has occurred.
PROBABLE CAUSES
• Malfunction of CAN bus line
• Malfunction of the KOS-ECU
• Malfunction of combination meter
