COMMENTS ON TROUBLE SYMPTOM

The wiring harness between the ETACS-ECU and 
the rear display unit, the ETACS-ECU or the multivi-
sion display may have a problem.

.

PROBABLE CAUSES

• The rear display unit may be defective

• The ETACS-ECU may be defective

• Damaged harness wires and connectors

DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

• MB992006: Extra Fine Probe

• 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

STEP 1. 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 : Diagnose the combination meter (Refer to 

P.54A-34

). 

On completion, go to Step 2.

NO :  Go to Step 2.

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

YES : Diagnose the ETACS-ECU (Refer to 

P.54A-733

), and 

then go to Step 3.

NO :  Go to Step 3.

STEP 3. Check combination meter connector C-03 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Is combination meter connector C-03 in good 

condition?
YES : Go to Step 4.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

.

STEP 4. Check the power supply circuit to the combination 
meter. Measure the voltage at combination meter 
connector C-03.
(1) Disconnect combination meter connector C-03, and 

measure the voltage available at the wiring harness-side 
connector.

(2) Turn the ignition switch to the "LOCK" (OFF) position.
(3) Measure the voltage terminal No.24 and the body ground.

OK: 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 6.
NO :  Go to Step 5.

STEP 5. Check the wiring harness between ETACS-ECU 
connector C-317 (terminal 2) and combination meter 
connector C-03 (terminal 24).

• Check the power supply line for open circuit and short cir-

cuit.

Q: Is the wiring harness between ETACS-ECU connector 

C-317 (terminal 2) and combination meter connector 
C-03 (terminal 24) in good condition?
YES : Replace the ETACS-ECU, then go to Step 6.
NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. 

STEP 6. Check the wiring harness between combination 
meter connector C-03 (terminal 23) and rear display unit 
connector D-06 (terminal 5).
NOTE: Also check intermediate connector D-123 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector D-123 is damaged, repair 
or replace the connector as described in GROUP 00E, Harness 
Connector Inspection 

P.00E-2

.

• Check the power supply line for open circuit and short cir-

cuit.

Q: Is the wiring harness between combination meter 

connector C-03 (terminal 23) and rear display unit 
connector D-06 (terminal 5) in good condition?
YES : Replace the rear display unit.
NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary.
