SERVICE PRECAUTIONS - DISCHARGE HEADLIGHT

Before checking the discharge headlight related parts, be sure to read the following warnings and precautions carefully, and then perform necessary operations.

WARNINGDo not touch the socket and the connector while the headlights are on. High voltage is applied to the bulb socket and connector during headlight operation. The operator may be burnt or dead due to an electric shock by high voltage. Do not attempt to use a tester to check them. If the bulb socket and connectors should be inspected using a tester, the operator may be burnt or dead due to an electric shock by high voltage. Do not turn ON the headlights while the controller or the bulb is removed. If the headlights are turned ON with the controller or bulb removed, the operator may get burned by the high temperature of the bulb. The operator may be burnt or dead due to an electric shock by high voltage. Before service work, turn the lighting switch OFF and disconnect the battery terminal and the controller connector in a dry place. Do not touch the components with wet hands. If you work on the components with wet hands or in wet conditions, the operator may be burnt or dead due to an electric shock by high voltage.
WARNINGDo not illuminate the bare headlight bulb. (Do not illuminate the headlight using other than the vehicle power supply.) If the headlight bulb illuminates without fitting it in the headlight unit, it may burst due to rise in its internal pressure.
CAUTIONWhen reusing the controller with the discharge headlight damaged, observe the inspection procedures for the related parts of the discharge headlight before determining the reusability of the controller. If you fail to observe "How to check discharge headlight components," the vehicle may be damaged.

VISUAL CHECK OF CONTROLLER (CASE)

If any of the check items below are found, replace the controller.

Items to be checkedWhy the controller should be replaced
Obvious deformation (warping, twisting, dents, nicks, chipped edges) of controller caseThe printed circuit board or the element(s) may be cracked
Damaged connector (chipped or cracked plastics, or deformed terminal)The damaged part(s) may cause poor connection or short circuit.

CONTROLLER REPLACEMENT

PROBABLE CAUSES

  1. Burned-out daytime running light bulb
  2. Malfunction of the daytime running light relay
  3. Malfunction of the ETACS-ECU
  4. Damaged harness wires and connectors

Scheme 60: PRE-AIMING INSTRUCTIONS (LOW-BEAM)
  1. Inspect for rusted or faulty headlight 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 (6.6 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. Turn the headlight leveling switch to the switch position "0." < Vehicles with headlight manual leveling system >
  7. Thoroughly clean headlight lenses.
  8. Place the vehicle on a level floor, perpendicular to a flat screen 7.62 m (25.0 ft) away from the bulb center-marks on the headlight lens.
  9. Rock vehicle sideways to allow vehicle to assume its normal position.
  10. Bounce the front suspension through three (3) oscillations by applying the body weight to hood or bumper.
  11. Set the distance between the screen and the bulb center marks of the headlight as shown in the illustration.
  12. Four lines of adhesive tape (or equivalent markings) are required on screen or wall: Position a vertical tape or mark so that it is aligned with the vehicle center line. Measure the distance from the center-marks on the headlight lens to the floor [reference value: 679.5 mm (26.75 inches)]. Transfer the measurement to the screen. Horizontal tape or mark on the screen is for reference of vertical adjustment. Measure the distance from the center line of the vehicle to the center of each headlight. Transfer the measurement to the screen. Vertical tape or mark on the screen with reference to the center line of each headlight bulb.

Scheme 61

Scheme 61: HEADLIGHT ADJUSTMENT (LOW-BEAM)
  1. The low-beam headlight will project on the screen upper edge of the beam (cut-off).
  2. Turn the adjusting screw to achieve the specified low-beam cut-off location on the aiming screen.

Standard value < Vehicles without discharge headlight >

(Vertical direction) Horizontal line (H) ± 50.5 mm (± 2.0 inches) (± 0.38 degrees angle)

(Horizontal direction): ± 126.4 mm (± 5.0 inches) (± 0.95 degrees angle) from the axis, which is 266.1 mm (10.5 inches) (2 degrees angle) rightward from the vertical line (V)

Scheme 62

Scheme 62

Standard value < Vehicles with discharge headlight >

(Vertical direction) 53.2 mm (2.1 inches) (0.4 degrees) below horizontal line (H). ± 50.5 mm (± 2.0 inches) (± 0.38 degrees angle)

(Horizontal direction): Elbow point intersects the vertical line (V). ± 126.4 mm (± 5.0 inches) (± 0.95 degrees angle)

Scheme 63

Scheme 63
CAUTIONDo not cover a headlight for more than three minutes to prevent the plastic headlight lens deformation.

Note. High-beam pattern should be correct when the low-beams are adjusted properly.

LUMINOUS INTENSITY MEASUREMENT

  1. Set the headlights to high-beam.
  2. Using a photometer, and following its manufacturer's instruction manual, measure the headlight center intensity and check to be sure that the limit value is satisfied.

Limit: 40, 000 cd or more {When a screen is set 18.3 m (60 feet) ahead of the vehicle}

Note. When measuring the intensity, maintain an engine speed of 2, 000 r/min, with the battery fully charged. There may be special local regulations pertaining to headlight intensity. Be sure to make any adjustments necessary to satisfy such regulations. If an illuminometer is used to make the measurements, convert its values to photometer values by using the following formula.

I = E x r 2

  1. I = intensity (cd)
  2. E = illumination (lux)
  3. r = distance (m) from headlights to illuminometer

HEADLIGHT AUTOMATIC-SHUTDOWN FUNCTION CHECK

Confirm that the headlights turn OFF in one second if the driver's door is opened when the ignition switch is OFF and the lighting switch is ON (HEAD position). If there is a malfunction, perform the troubleshooting (Refer to TROUBLE SYMPTOM CHART ).

HEADLIGHT AUTO LIGHT FUNCTION CHECK

Under the direct sunlight with the ignition switch ON and the lighting switch in the AUTO position, check that the headlight automatically illuminates when the lighting control sensor receiver is covered by hand. If there is any trouble, carry out the troubleshooting. (Refer to TROUBLE SYMPTOM CHART ).

Note. When covering the lighting control sensor receiver, be careful not to touch the windshield surface (where the lighting control sensor receiver is mounted). (The lighting control sensor receiver has limited resistance to oil.)

WELCOME LIGHT FUNCTION CHECK

When the lighting switch is in the OFF or AUTO position, unlock the door by the keyless entry system and check that the taillights or headlights turn on. If there is a malfunction, perform the troubleshooting (Refer to TROUBLE SYMPTOM CHART ).

Note. As for the vehicles with lighting control sensor, carry out the inspection in the dark place.

COMING-HOME LIGHT FUNCTION CHECK

After turning the ignition switch to the LOCK (OFF) position, check that passing operation lights up the headlights. If there is a malfunction, perform the troubleshooting (Refer to TROUBLE SYMPTOM CHART ).

LIGHTING CONTROL SENSOR (LIGHT SENSOR) CHECK

Using the scan tool MB991958, check the LIN data list as follows.

  1. Under the direct sunlight, turn the ignition switch to the ON position and the lighting switch to the AUTO position.
  2. When the lighting control sensor receiver is covered by hand, and if the item No. 7009 (RLS Low beam "ON" request) and the item No. 7011 (RLS Taillight "ON" request) turn from OFF to ON, it is judged normal.

Note. Before inspection using the scan tool MB991958, wipe off the windshield clearly. Then check that there is no abnormality on the windshield surface where the lighting control sensor is mounted. When covering the lighting control sensor receiver, be careful not to touch the windshield surface (where the lighting control sensor receiver is mounted). (The lighting control sensor receiver has limited resistance to oil.)
