4. HEADLAMP AUTO LEVERING OPERATION CHECK
(a) Check that the initialization (determination of the initial position) for the leveling motor is performed at
the engine±start.
(b) Check that the warning indicator in the combination meter assy illuminates for approximately 3 se-
conds at the engine±start and then goes off.
(c) Check that the reflector works when:
Keeping the rear of the vehicle up or down while the engine is running with the vehicle stopped and
the headlamp dimmer switch in the HEAD position.
NOTICE:
Make sure to change the vehicle's height slowly.

ConditionContent
Output openLighting of the headlamp stops, the condition is maintained until
switch is turned ON again (headlamp dimmer switch OFF
ON).
Short between output terminalsLighting of the headlamp stops, the condition is maintained until
switch is turned ON again (headlamp dimmer switch OFF
ON).
Leakage between output terminal and body groundLighting of the headlamp stops, the condition is maintained until
switch is turned ON again (headlamp dimmer switch OFF
ON).
Low lamp voltageLighting of the headlamp stops, the condition is maintained until
switch is turned ON again (headlamp dimmer switch OFF
ON).
High lamp voltageLighting of the headlamp stops, the condition is maintained until
switch is turned ON again (headlamp dimmer switch OFF
ON).
Bulb flushing

The condition is maintained more than 60 seconds.

Lighting of the headlamp stops, the condition is maintained until
switch is turned ON again (headlamp dimmer switch OFF

ON).
High input voltageLighting of the headlamp stops. As soon as the voltage comes
within the range of operation voltage (9 ± 16 V), it lights up again.
Low input voltage
When voltage become 9.0 V
7.5 V, lighting condition is main-
tained until possible voltage (Below 6 V) to keep lighting and light-
ing of the headlamp stops.
As soon as the voltage becomes within the range of operation
voltage (more than 9 V), it lights up again.
