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 the
scan tool (M.U.T.-III) P.54Af-4."

(2)

Turn the ignition switch to the "ON" position.

(3)

Read  out  the  option  coding  information  in  ETACS-ECU.
(Refer to GROUP 00, Coding Table .)

(4)

Check that the "Front fog light" is set to "YES."

(5)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the ETACS-ECU coding data normal?

YES:

 Go to Step 2.

NO:

 Operate scan tool MB991958 to set the option coding

"Front fog light" to "Yes," and check the trouble symptom.

STEP 2. Check that the tail/stop lights and headlights
operate.
Check that the tail/stop lights and headlights illuminate normally.

Q:Do the tail/stop lights and headlights operate normally?

YES:

 Go to Step 3.

NO:

 Check the tail/stop lights and the headlights (Refer

to trouble symptom chart P.54Ac-114).

STEP 3. Using scan tool MB991958, read the other system
diagnostic trouble code.
Check if DTC is set to the ETACS-ECU.

(1)

Turn the ignition switch to the "ON" position.

(2)

Check whether the ETACS-ECU related DTC is set.

(3)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the DTC set?

YES:

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

Diagnosis P.54Ad-8).

NO:

 Go to Step 4.

STEP 4. Using scan tool MB991958, check data list.

DIAGNOSIS

YES:

 Go to Step 5.

NO:

 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-89.

STEP 5. Check fog light relay connector A-14X for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is fog light relay connector A-14X in good condition?

YES:

 Go to Step 6.

NO:

 Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2. Verify
that the fog lights illuminate normally.

STEP 6. Check the fog light relay.
Refer to P.54Ac-187.

Q:Is the fog light relay in good condition?

YES:

 Go to Step 7.

NO:

 Replace the fog light relay. Verify that the fog

lights illuminate normally.

STEP 7. Check the battery power supply circuit to the fog
light relay. Measure the voltage at fog light relay connector
A-14X.

The  top  and  bottom  of  the  fog  light  relay  are  difficult  to
identify. Prior to inspection, confirm the triangle mark on
the relay box.

(1)

Disconnect fog light relay connector A-14X and measure the
voltage available at the relay box side of the connector.

ZC5010400050

CONNECTOR A-14X 
(RELAY BOX SIDE)

(2)

Measure  the  voltage  between  terminal  3  and  ground,  and
between terminal 4 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 9.

NO:

 Go to Step 8.

STEP 8. Check the wiring harness between fog light relay
connector A-14X (terminal 2 and 4) and fusible link (36).

Check the power supply line for open circuit.

Q:Is the wiring harness between fog light relay connector

A-14X  (terminal  2  and  4)  and  fusible  link  (36)  in  good

condition?

YES:

 Go to Step 13.

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. Verify that the front fog lights
illuminate normally.

STEP 9. Check ETACS-ECU connector C-312 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is ETACS-ECU connector C-312 in good condition?

YES:

 Go to Step 10.

NO:

 Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2. Verify
that the fog lights illuminate normally.

STEP 10. Check the wiring harness between fog light relay
connector A-14X (terminal 1) and ETACS-ECU connector
C-312 (terminal 4).

NOTE: 

Also check intermediate connector A-46 for loose,

corroded, or damaged terminals, or terminals pushed back in
the connector. If intermediate connector A-46 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.

Q:Is the wiring harness between fog light relay connector

A-14X  (terminal  3)  and  fog  light  (LH)  connector  A-41
