TROUBLESHOOTING HINTS

• The combination meter may be defective

• The each ECU may be defective

DIAGNOSIS 

Required Special Tools:

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

• MB991824: Vehicle 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-25

."

(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-14

STEP 2. Using scan tool MB991958, read the combination 
meter diagnostic trouble code.
Check if DTC is set to the combination meter.
Q: Is the DTC set?

YES : Troubleshoot the combination meter (Refer to 

P.54A-28

).

NO :  Go to Step 3.

STEP 3. Using scan tool MB991958, read for any 
diagnostic trouble code.
Check if diagnostic trouble code is set to the engine control 
module, TC-SST-ECU, ASC-ECU, ETACS-ECU, WCM, 
KOS-ECU, audio and A/C-ECU.
Q: Is the DTC set to the any of the above?

Inspection Procedure 5: The combination meter light does not illuminate normally or the multi 
information display is not displayed normally.

CAUTION

Before replacing the combination meter, be sure 
to check that the power supply circuit, ground 
circuit, and communication circuit are normal.

.

TECHNICAL DESCRIPTION (COMMENT)

When the signal from each ECU is received via the 
CAN communication, the combination meter illumi-
nates the corresponding display light or warning 
light, or has the multi information display to display 
corresponding information.

If the lights do not illuminate or the multi information 
display does not display normally, the wiring harness 
and connector(s) in the CAN bus lines, or the each 
ECU or the combination meter may have a problem.

.

TROUBLESHOOTING HINTS

• The combination meter may be defective

• The each ECU may be defective
