SERVICE PRECAUTIONS DISCHARGE HEADLIGHT

M1540100300162

Before checking the discharge headlight related 
parts, be sure to read the following warnings and pre-
cautions carefully, and then perform necessary oper-
ations.

DANGER

Do not touch the socket and the connec-
tor while the headlights are on. High volt-
age 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 control-
ler 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 compo-
nents with wet hands or in wet conditions, 
the operator may be burnt or dead due to 
an electric shock by high voltage.

WARNING

Do not illuminate the bare headlight bulb. 
(Do not illuminate the headlight using other 
than the vehicle power supply.) If the head-
light bulb illuminates without fitting it in the 
headlight unit, it may burst due to rise in its 
internal pressure.

CAUTION

When reusing the controller with the discharge 
headlight damaged, observe the inspection pro-
cedures 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.

1. CHECKING PROCEDURE FOR DISCHARGE HEADLIGHT RELATED PARTS 
(INSPECTION PROCEDURE WHEN REUSING THE CONTROLLER)

.

 1 VISUAL CHECK OF CONTROLLER (CASE)

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

.

 2 CHECK OF WIRING HARNESS BETWEEN CONTROLLER AND BULB

If any of the check items below are found, replace 
the wiring harness between the controller and the 
bulb.

DANGER

If the wiring harness between the controller 
and the bulb is damaged, always replace it. 
Attempting to repair the wiring harness may 
cause a melted harness wire, or may result in 
a burn or death due to an electric shock by 
high voltage.

.

 3 CHECK OF CONTROLLER OPERATION

If any of the abnormalities below are found, replace 
the controller.

NOTE: Ensure that the headlight control system and 
its circuit (power supply control at engine start and 
during steady illumination, high-voltage generating 
circuit, etc.) are working normally. Then, check 
whether any internal breakage has occurred in the 
controller. However, some internal breakage may not 
be found.

Items to be checked

Why the controller should be replaced

Obvious deformation (warping, twisting, dents, nicks, 
chipped edges) of controller case

The 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.

Items to be checked

Why the controller should be replaced

Wiring harness shield damaged

Abnormal noise may cause.

Damaged connector (chipped or cracked plastics, or 
deformed terminal)

The damaged part(s) may cause poor connection or 
short circuit.

Check item (Check of illumination operation)
With the headlight bulb in the cold state (with the light turned off for 10 minutes or more) and in warm state 
(after the light is illuminated for 15 minutes or more, it is turned off for 1 minute), turn ON and OFF the 
headlight several times, and then check that the headlight illuminates without fail.
Observe the headlights until they illuminate steadily (approximately five minutes after switching them on). 
Check that the headlights do not flash or flicker.
Turn on the headlights for thirty minutes. Check that the brightness is the same between right and left lights.
Turn on the headlights for thirty minutes. Check that the headlights do not flash or flicker for thirty minutes.

2. Troubleshooting procedure for discharge headlight (diagnostic procedure for 
malfunctions)

1. Check that the connectors are connected 

securely and the fuse has not been blown.

2. Before troubleshooting, read through the "Symp-

tom chart" to understand what and how you 
should do. Follow all the procedures carefully.

3. The components should be checked with their 

connectors disconnected.

SYMPTOM CHART

NOTE: 

.

1. The numbers indicate the sequence in which the 

component is checked.

2. For the troubleshooting of other than the above, 

refer to Trouble Symptom Chart 

P.54A-153

.

3. If ETACS-ECU fails, only the low-beam head-

lights will illuminate as a fail-safe measure.

DIAGNOSTIC TROUBLE CODE CHART

M1540101400429

CAUTION

On troubleshooting, if the ignition switch is 
turned ON while disconnecting connector(s), 
diagnostic trouble code(s) associated with other 
system may be set. On completion, confirm all 
systems for diagnostic trouble code(s). If diag-
nostic trouble code(s) are set, erase them all.
