STEP 4. Recheck for diagnostic trouble code.
Check again if the DTC is set to the combination meter.
(1) Erase the DTC.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON"

position.

(3) Check if DTC is set.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?

YES : Replace the A/C-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 combination
meter (Refer to GROUP 00, How to Cope with
Intermittent Malfunction

P.00-15

).

STEP 5. Recheck for diagnostic trouble code.
Check again if the DTC is set to the combination meter.
(1) Erase the DTC.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON"

position.

(3) Check if DTC is set.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?

YES : Replace the combination meter.
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 combination
meter (Refer to GROUP 00, How to Cope with

DTC U0168: KOS-ECU or WCM CAN timeout

CAUTION

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

CAN bus line.

• When replacing the ECU, always check that

the communication circuit is normal.

.

DIAGNOSTIC FUNCTION

If the signal from KOS-ECU or WCM cannot be
received, the combination meter 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 or WCM cannot be estab-
lished for 2,500 ms or more, the combination meter
determines that a problem has occurred.

.

TROUBLESHOOTING HINTS

• Malfunction of CAN bus line may be defective.

• Malfunction of the KOS-ECU may be defective.

• Malfunction of the WCM may be defective.

• Malfunction of combination meter 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-31

."

(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 or
WCM diagnostic trouble code.
Check again if the DTC is set to the KOS-ECU or WCM.
Q: Is the DTC set?

YES : Troubleshoot the KOS or WCM (Refer to GROUP

42B, Troubleshooting

P.42B-35

<KOS> or 42C,

Troubleshooting

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 U0184: Audio CAN timeout

CAUTION

• If DTC U0184 is set, be sure to diagnose the

CAN bus line.

• When replacing the ECU, always check that

the communication circuit is normal.

.

DIAGNOSTIC FUNCTION

When the signals from radio and CD player or CD
changer cannot be received, the combination meter
sets the DTC U0184.

.

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 radio and CD player or CD
changer cannot be established for 2,500 ms or more,
the combination meter determines that a problem
has occurred.

.
