STEP 6. Check the wiring harness between fog light (LH)
connector A-41or fog light (RH) connector A-51 (terminal
2) and fog light relay connector A-14X (terminal 3).
NOTE: Also check intermediate connector A-46 for loose, cor-
roded, 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 (LH) connector

A-41 or fog light (RH) connector A-51 (terminal 2) and
fog light relay connector A-14X (terminal 3) in good
condition?
YES : Go to Step 7.
NO : Repair the wiring harness.

STEP 7. Retest the system.
Q: Does the right or left fog light illuminate 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 : Go to Step 1.

Inspection Procedure 3: Fog light indicator does not illuminate/go out normally.

CAUTION

Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.

.

TECHNICAL DESCRIPTION (COMMENT)

If the fog light indicator does not illuminate normally, connec-
tor(s), wiring harness in the CAN bus lines, the ETACS-ECU or
the combination meter may be defective.

• The combination meter may be defective

• Damaged harness wires and connectors

DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

STEP 1. Check the fog lights.
When the fog light switch is operated, check that the fog lights
illuminate/go off normally.
Q: Is the fog lights normal?

YES : Go to Step 2.
NO : First, repair the fog lights. Refer to Inspection

Procedure 2 "One of the front fog lights does not
illuminate

P.54A-266

."

STEP 2. Using scan tool MB991958, diagnose the CAN bus
line.

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 the

scan tool (M.U.T.-III)

P.54A-257

."

(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 3.
NO : Repair the CAN bus line (Refer to GROUP 54C

STEP 3. Using scan tool MB991958, read the combination
meter diagnostic trouble code.
(1) Check whether a combination meter-related DTC is set.
(2) Turn the ignition switch to the "ON" position.

Check whether the combination meter-related DTC is set.

(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?

YES : Diagnose the combination meter (Refer to Diagnosis

P.54A-34

).

NO : Go to Step 4.

STEP 4. Using scan tool MB991958, check actuator test.
(1) Turn the ignition switch to the "ON" position.
(2) Perform the actuator test for the combination meter, and

check that the fog light indicator illuminates (Refer to

P.54A-91

).

(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the check result normal?

YES : Replace the ETACS-ECU.
NO : Replace the combination meter.

ON-VEHICLE SERVICE

FRONT FOG LIGHT AIMING

M1540400300635

PRE-AIMING INSTRUCTIONS

1. Inspect for rusted or faulty front fog light assemblies.
2. These conditions must be corrected before a satisfactory

adjustment can be made.

3. Inspect tire inflation, and adjust if necessary.
4. If the fuel tank is not full, place a weight in the trunk of the

vehicle to simulate weight of a full tank [3 kg (6.5 pounds)
per gallon].

5. There should be no other load in the vehicle other than

driver or substituted weight of approximately 68 kg (150
pounds) placed in driver's position.

6. Thoroughly clean the front fog light lenses.
7. Place the vehicle on a level floor, perpendicular to a flat

screen 7.62 meters (25.0 ft) away from the bulb
center-marks on the fog light lens.

8. Rock the vehicle sideways to allow the vehicle to assume its

normal position.

9. Bounce the front suspension through three (3) oscillations

by applying the body weight to the hood or bumper.

10.Measure the center of the front fog lights as shown in the

illustration.

11.Four lines of adhesive tape (or equivalent markings) are

required on screen or wall:

(1) Position a vertical tape or mark so that it is aligned with

the vehicle center line.

(2) Measure the distance from the center of the front fog light

lens to the floor. Transfer the measurement to the screen.
Horizontal tape or mark on the screen is for reference of
vertical adjustment.

(3) Measure the distance from the center line of the vehicle

to the center of each front fog light. Transfer the
measurement to the screen. Vertical tape or mark on the
screen is for reference to the center line of each front fog
light.

FOG LIGHT ADJUSTMENT

1. Check if the beam shining onto the screen is at the standard

value.

Standard value:

(Cutoff line direction): The horizontal line (H) 153.0

mm (6.02 inches) (1.15 degrees angle) below the
horizontal line (H)

Limit:

(Vertical direction): Area from 53.2 mm (2.09 inches)

(0.4 degrees angle) above the cutoff line to 99.8
mm (3.93 inches) (0.75 degrees angle) below the
cutoff line

(Horizontal direction): Vertical line (V)

± 599.7 mm (±

23.6 inches) (

± 4.5 degrees angle)

2. If it is not within the standard value range, adjust by turning

the adjusting screw.

NOTE: The horizontal direction is non-adjustable. If deviation of
the light beam axis exceeds the standard value, check that the
mounting location or some other points are not faulty.
