STEP 4. Check the wiring harness between combination 
meter connector C-03 (terminal 1) and the fusible link (36).

• Check the power supply line (battery supply) for open circuit 

and short circuit.

NOTE: Also check ETACS-ECU connectors C-307 and C-317 
for loose, corroded, or damaged terminals, or terminals pushed 
back in the connector. If ETACS-ECU connector C-307 or 
C-317 is damaged, repair or replace the damaged compo-
nent(s) as described in GROUP 00E, Harness Connector 
Inspection 

P.00E-2

. 

Q: Is the wiring harness between combination meter 

connector C-03 (terminal 1) and the fusible link (36) in 
good condition?
YES : The trouble can be an intermittent malfunction (Refer 

to GROUP 00 

− How to Cope with Intermittent 

Malfunction 

P.00-15

).

NO :  Repair the wiring harness.

STEP 5. Check the battery power supply circuit to the 
combination meter. Measure the voltage at combination 
meter connector C-03.
(1) Disconnect the connector, and measure at the wiring 

harness side.

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between terminals 2 and ground.

• The voltage should measure approximately 12 volts 

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : Go to Step 8.
NO :  Go to Step 6.

STEP 6. Using scan tool MB991958, check data list.
Check the input signal from the ignition switch (IG1) in the 
ETACS-ECU.
(1) Turn the ignition switch to the "ON" position.
(2) Check the ETACS data list.

• Turn the ignition switch to the "ON" position.

(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Does the scan tool MB991958 display the item "IG 

voltage" is normal condition?
YES : Go to Step 7.
NO  :  Troubleshoot the ETACS-ECU. Refer to Inspection 

Procedure 2 "The ignition switch (IG1) signal is not 
received 

P.54A-788

."

STEP 7. Check the wiring harness between combination 
meter connector C-03 (terminal 2) and the fusible link (34).

• Check the power supply line (battery supply) for open circuit 

and short circuit.

NOTE: Also check ETACS-ECU connectors C-309 and C-317 
for loose, corroded, or damaged terminals, or terminals pushed 
back in the connector. If ETACS-ECU connector C-309 or 
C-317 is damaged, repair or replace the damaged compo-
nent(s) as described in GROUP 00E, Harness Connector 
Inspection

. 

Q: Is the wiring harness between combination meter 

connector C-03 (terminal 2) and the fusible link (34) in 
good condition?
YES : The trouble can be an intermittent malfunction (Refer 

to GROUP 00 

− How to use 

Troubleshooting/inspection Service Points 

− How to 

Cope with Intermittent Malfunction 

P.00-15

).

NO :  Repair the wiring harness.

STEP 8. Check the ground circuit to the combination 
meter. Test at combination meter connector C-03.
(1) Disconnect combination meter connector C-03 and 

measure the resistance available at the wiring harness side 
of the connector.

(2) Measure the resistance value between terminal 13 and 

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 10.
NO :  Go to Step 9.

STEP 9. Check the wiring harness between combination 
meter connector C-03 (terminal 13) and ground.

• Check the ground wire for open circuit.

Q: Is the wiring harness between combination meter 

connector C-03 (terminal 13) and ground in good 
condition?
YES : The trouble can be an intermittent malfunction (Refer 

to GROUP 00 

− How to use 

Troubleshooting/inspection Service Points 

− How to 

Cope with Intermittent Malfunction 

P.00-15

).

NO :  Repair the wiring harness.

STEP 10. Retest the system.
Check that the combination meter works normally.
Q: Is the check result satisfactory?

YES : The trouble can be an intermittent malfunction (Refer 

to GROUP 00 

− How to use 

Troubleshooting/inspection Service Points 

− How to 

Cope with Intermittent Malfunction 

P.00-15

).

NO :  Replace the combination meter.

Inspection Procedure 2: The speedometer does not work (the other meters work).

.

TECHNICAL DESCRIPTION (COMMENT)

If only the speedometer does not operate, the 
ABS-ECU <Vehicles without ASC> or ASC-ECU 
<Vehicles with ASC> and combination meter may 
have a problem.

.

TROUBLESHOOTING HINTS

• The ABS-ECU may be defective <Vehicles with-

out ASC>

• The ASC-ECU may be defective <Vehicles with 

ASC>

• The combination meter may be defective

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)

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 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-34

).

NO :  Go to Step 3.

STEP 3. Using scan tool MB991958, read the ABS-ECU 
<Vehicles without ASC> or ASC-ECU <Vehicles with ASC> 
diagnostic trouble code.
Check if diagnostic trouble code is set to the ABS-ECU or 
ASC-ECU.
Q: Is the DTC set?

YES : Troubleshoot the ABS or ASC (Refer to GROUP 35B, 

Diagnosis 

P.35B-15

 <ABS> or GROUP 35C,
