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 engine control module.
NO :  The trouble can be an intermittent malfunction such 

as a poor connection or open circuit in the CAN bus 
lines between the engine control module 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 engine control module and the 
combination meter (Refer to GROUP 00, How to

DTC U0141: ETACS CAN timeout

CAUTION

• If DTC U0141 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 ETACS-ECU cannot be received, 
the combination meter sets the DTC U0141.

.

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 communication with ETACS-ECU cannot be 
established for 2,500 ms or more, the combination 
meter determines that a problem has occurred.

.

TROUBLESHOOTING HINTS

• The CAN bus line may be defective

• The combination meter may be defective

• The ETACS-ECU may be defective

DIAGNOSIS

Required Special Tools:

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

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.

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 ETACS 
diagnostic trouble code.
Check if DTC is set to the ETACS-ECU.
Q: Is the DTC set?

YES : Diagnose the ETACS-ECU (Refer to 

P.54A-732

).

NO :  Go to Step 3.

STEP 3. Using scan tool MB991958, read the A/C 
diagnostic trouble code.
Check if DTC U0141 is set to the A/C-ECU.
Q: Is the DTC set?

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