To prevent damage to scan tool MB991958, always turn the
ignition  switch  to  the  "LOCK"  (OFF)  position  before
connecting or disconnecting scan tool MB991958.

(1)

Connect scan tool MB991958. Refer to "How to connect scan
too (M.U.T.-III) P.54Ac-99."

(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?

 Diagnose the ETACS-ECU. Refer to GROUP 54Ad,

Diagnosis P.54Ad-8.

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.

218.>:

 Troubleshoot the ETACS-ECU.Refer to GROUP 54Ad,

Diagnosis - Inspection Procedure 12 "ETACS-ECU does not
receive any signal from the column switch signal" P.
54Ad-73.

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 - How to use Troubleshooting/
inspection Service Points - How to Cope with Intermittent
Malfunction P.00-15).

NO:

 Replace the ETACS-ECU.

Inspection Procedure 2: Any of the taillights do not illuminate.

TECHNICAL DESCRIPTION (COMMENT)
If  any  of  the  taillights  do  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  terminals
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)

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

DIAGNOSIS

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.

ZC5015310002

Connector D-09 
(Harness side)

ZC5015310005

Connector D-14 
(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.

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).

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?
