INSPECTION PROCEDURE 24
Power supply system and ignition switch-IG system
Probable cause
When an ignition switch ON signal is input to the engine-ECU, the engine-ECU turns
the control relay ON. This causes system voltage to be supplied to the engine-ECU,
injectors and air flow sensor.
Malfunction of the ignition switch

Malfunction of the control relay

ON-VEHICLE SERVICE
HEADLAMP AIMING
Bring the vehicle in the following conditions before aiming
the headlamp.

Check the tires for inflation pressure. Pump them up if
necessary to the labeled pressure level.

Set the vehicle unladen on a level floor.

Place one person (approximately 55 kg) on the driver’s
seat.

Maintain an engine speed of 2,000 r/min to keep the
battery in the charged condition.
1. Position the tester so that its converging lens faces the
fog lamp center to center at a distance of 10 m.
NOTE
Measure the center of the fog lamp as shown.
A: 572.5 mm (from the center of the vehicle body)
B: 360 mm
2. Remove the fog lamp bezel, and using the aiming
adjustment screw, aim the fog lamp to the standard value.
NOTE
The horizontal direction is non-adjustable. If the beam
axis deviation exceeds the standard value, check the
fog lamp to determine if it is installed out of position and
correct if necessary.

Horizontal direction3° (524 mm) leftward from
vertical line (V)
Caution:
(1) Perform aiming adjustments, one light at a time,
with the other headlamp disconnected so as not
to be lit unless circumstances compel otherwise.
When reconnecting the headlamps, be careful not
to upset their aim. Do not leave the headlamps
on for any longer than 3 minutes if their outer
lenses are covered with a surface covering
impervious to light.
(2) Do not mask the outer lenses by taping or in any
other way.
(3) Aiming adjustment must be completed with the
aiming adjustment screws turned in the tightening
direction.
FOG LAMP BULB REPLACEMENT
1. Remove the fog lamp.
2. Remove the cover.
3. Unhook the spring which secures the bulb and then
replace the bulb.
Caution
(1) Do not touch the surface of the bulb with hands
or dirty gloves. If the surface does become dirty,
clean it with alcohol or thinner, and let it dry
thoroughly before installing.
(2) To prevent the clouding of lens and ingress of
water into the lamp unit, install the socket cover
correctly.
