MOBILE COMMUNICATION SYSTEM
If the vehicle is equipped with a mobile communication system, refer to precautions in the IN section.

LIGHTING SYSTEM
Halogen bulbs have pressurized gas inside and require special handling.
They can burst or scatter if scratched or dropped. Hold a bulb only by its plastic or metal case.
Don’t touch the glass part of a bulb with bare hands.
When high voltage socket of discharge headlight is touched with the light control switch HEAD, high
voltage of 20,000 V is momentarily generated. This might lead to a serious accident.
Never connect the tester to the high voltage socket of discharge headlight for measurement, as this
leads to a serious because of high voltage.
When performing operation related to the discharge headlight, make sure to do it in the place with no
water of rain to prevent electric shock, with light control switch OFF, battery terminal removed, connec-
tor of light control ECU disconnected.
When performing operation related to the discharge headlight, make sure to do it after assembling has
been completely over and never light up without a bulb installed.
Do not light up the discharge headlight using another power source except vehicle’s.
When there is a defect on the discharge headlight or any shock has been applied to it, replace the light
with a new one.
Even if the light operates normally, there is a possibility that the fail–safe function not works.

INSPECTION
1.
INSPECT TENSION REDUCER SOLENOID OPERA-
TION
(a)
Connect the positive (+) lead from the battery to terminal
1, and negative (–) lead to terminal 2.
(b)
Pull the belt upward and check that the belt is slowly re-
tracted when released.
(c)
Disconnect the lead from the battery.
(d)
Pull the belt upward and check that the belt is retracted
more quickly when released than in (b).
HINT:
Do not tilt the retractor.
If the operation is not as specified, replace the front seat outer
belt assembly.
2.
INSPECT TENSION REDUCER SOLENOID CIRCUIT
Disconnect the tension reducer solenoid connector and inspect
the connector on wire harness side, as shown.
