STEP 2. Using scan tool MB991958, read the diagnostic 
trouble code. 

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 

scan too (M.U.T.-III) 

P.54A-227

."

(2) Turn the ignition switch to the "ON" position.
(3) Check whether the ETACS-ECU related DTC is set.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
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, check data list. 
Use the ETACS-ECU data list to check the signals related to 
the taillight illumination.

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

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

Q: Does scan tool MB991958 display the items "Taillight" 

as normal condition?
YES <Normal condition is displayed for item.> : 
Go to 

Step 4.

NO <Normal condition is not displayed for item No. 
218.> : 
Troubleshoot the ETACS-ECU. Refer to Inspection 

Procedure 12 "ETACS-ECU does not receive any 
signal from the column switch signal"

STEP 4. Retest the system
Check that the taillight illuminates normally.
Q: Does the taillight work normally?

YES : The trouble can be an intermittent malfunction (Refer 

to GROUP 00

TECHNICAL DESCRIPTION (COMMENT)

When one of the taillights does not illuminate, the 
wiring harness, connector(s), or rear combination 
light unit may have a problem, or the fuse may be 
burned out.

.

TROUBLESHOOTING HINTS

• Malfunction of rear combination light unit

• The wiring harness or connectors may have 

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

DIAGNOSIS

Required Special Tools:

• MB992006: Extra fine probe

• MB991223: Harness set

• 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. Check rear combination light connectors D-09 
(RH) and D-14 (LH) for loose, corroded or damaged 
terminals, or terminals pushed back in the connector.
Q: Is rear combination light connectors D-09 (RH) and D-14 

(LH) in good condition?
YES : 
Go to Step 2.
NO :  Repair the damaged parts

STEP 2. Resistance measurement at rear combination light 
connectors D-09 (RH) and D-14 (LH).
(1) Disconnect the connector, and measure at the wiring 

harness side.

(2) Measure the resistance between the connector of light 

which does not illuminate and body ground.

Measure the resistance between rear combination light 
connector D-09 (RH) (terminal No. 4) and body ground.

Measure the resistance between rear combination light 
connector D-14 (LH) ( terminal No. 4) and body ground.

The measured value should be continuity exists (2 
Ω or less).

Q: Does the measured resistance value correspond with 

this range?
YES : 
Go to Step 4.
NO :  Go to Step 3.

STEP 3. Check the wiring harness between rear 
combination light connectors D-09 (RH) and D-14 (LH) 
(terminal No. 4) and ground.
Check the ground line for open circuit.
Q: Is the check result normal?

YES : Go to Step 4.
NO :  Repair the wiring harness.

STEP 4. Check ETACS-ECU connectors C-311 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is ETACS-ECU connectors C-311 in good condition?

YES : Go to Step 5.
NO :  Repair the damaged parts.

STEP 5. Check the wiring harness between rear 
combination light connector D-09 (RH), D-14 (LH) and 
ETACS-ECU connector C-311 (terminal No. 13) (RH), 
(terminal No. 10) (LH).
Check the communication line for open or short circuit.
Q: Is the wiring harness between rear combination light 

connector D-09 (RH), D-14 (LH) and ETACS-ECU 
connector C-311 (terminal No. 13) (RH), (terminal No. 10) 
(LH) in good condition?
YES : 
Go to Step 6.
NO :  Repair the wiring harness.

STEP 6. Retest the system.
Check that the taillight illuminates normally.
Q: Does the taillight work normally?

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
