as a poor connection or open circuit in the CAN bus 
lines between the A/C-ECU and the radio and CD 
player (Refer to GROUP 00, How to Cope with 
Intermittent Malfunction

DTC U0168: WCM/KOS CAN timeout

CAUTION

• If DTC U0168 is set, be sure to diagnose the 

CAN bus line.

• When replacing the radio and CD player, 

always check that the communication circuit 
is normal.

.

DIAGNOSTIC FUNCTION

If the signal from KOS-ECU <vehicles with KOS> or 
WCM <vehicles with WCM> cannot be received, the 
radio and CD player sets DTC U0168.

.

JUDGMENT CRITERIA

With the ignition switch in the ON position, system 
voltage between 10 

− 16 V (data from ETACS-ECU), 

power supply fuse(IOD fuse) is OK, or odometer 
value is 80.5 km (50 miles) or more, and the commu-
nication with KOS-ECU <vehicles with KOS> or 
WCM <vehicles with WCM> cannot be established 
for 2,500 ms or more, the radio and CD player deter-
mines that a problem has occurred.

.

TROUBLESHOOTING HINTS

• Malfunction of CAN bus line may be defective.

• Malfunction of the KOS-ECU may be defective. 

<vehicles with KOS>

• Malfunction of the WCM may be defective. <vehi-

cles with WCM>

• Malfunction of radio and CD player may be defec-

tive.

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicles 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-331

."

(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, 

Diagnosis 

P.54C-17

).

STEP 2. Using scan tool MB991958, read the KOS-ECU 
<vehicles with KOS> or WCM <vehicles with WCM> 
diagnostic trouble code.
Check again if the DTC is set to the KOS-ECU <vehicles with 
KOS> or WCM <vehicles with WCM>.
Q: Is the DTC set?

YES : Troubleshoot the KOS or WCM (Refer to GROUP 

42B, Diagnosis 

P.42B-35

 <KOS> or GROUP 42C, 

Diagnosis 

P.42C-18

 <WCM>).

NO :  Go to Step 3.

STEP 3. Using scan tool MB991958, read the diagnostic 
trouble code.
Check if the DTC U0168 is set to the ETACS-ECU.
Q: Is the DTC set?

YES : Go to Step 4.
NO :  Go to Step 5.

DTC U0195: Satellite radio CAN timeout

CAUTION

If DTC U0195 is set in the radio and CD player, 
diagnose the CAN main bus line.

CAUTION

Whenever the ECU is replaced, ensure that the 
communication circuit is normal.

.

DIAGNOSTIC FUNCTION

When the signals from satellite radio tuner cannot be 
received, the radio and CD player sets DTC U0195.

.

JUDGMENT CRITERIA

With the ignition switch in the ON position, system 
voltage between 10 

− 16 volts (data from 

ETACS-ECU), power supply fuse(IOD fuse) is OK, or 
odometer value is 80.5 km (50 miles) or more, and 
the communications with satellite radio tuner cannot 
be established for 2,500 ms or more, the radio and 
CD player determines that a problem has occurred.

.

TROUBLESHOOTING HINTS

• The CAN bus line may be defective.

• The radio and CD player may be defective.

• The satellite radio tuner may be defective.
