ADJUST HEADLIGHT AIM ONLY
(a) Place the vehicle in the following conditions.
The area around the headlight is not deformed.
The vehicle is parked on a level surface.
Tire inflation pressure is the specified value.
A driver is in the driver's seat and the vehicle is in a state ready for driving (with a tank full).
The vehicle has been bounced several times.
(b) Check the headlight aiming.
(1) Prepare a thick white paper.
(2) Stand the paper perpendicular to the ground at the position 9.84 ft away from the headlights.
(3) Ensure that the center line of the vehicle and the paper face forms a 90-degree angle as shown
in the illustration.
(4) Draw a horizontal line (H line) on the paper, showing where the headlights should strike.
(5) Draw a vertical line (V line) to where the center line of the vehicle is to be.
(6) Draw 2 vertical lines (by connecting the low and high beam center marks) to where the both head-
lights should strike (V RH and V LH lines).
(7) Draw a horizontal line (by connecting the both low beam center marks) to where the headlights
should strike (H RH and H LH lines).
HINT:
The H RH and H LH line is 0.4° below the horizontal line (H line) of the light axis.
(8) Start the engine.
(9) Turn the headlights ON.
(10) Check that the headlights properly strike the position shown in the illustration.
(11) If not, adjust the lights in the vertical direction.
HINT:
As shown in the illustration, adjust each aim of the RH and LH lights.
(c) When adjusting it in the vertical direction:
Using adjusting bolt A, adjust the headlight aim to within the specified range.

4. INSPECT ENGINE ROOM R/B RELAY CIRCUIT (See
Pase BE-15)
HINT:
The (Headlight, DIM, Tail relay) is built in engine room junction
block. Also the relay is constructed with a relay block that is in
the junction block as a unit. To disconnect the wire harness con-
necting with relay block is impossible. If the relay has a malfunc-
tion, replace it with junction block assembly wire harness to-
gether.
5. Connector disconnected:
INSPECT AUTOMATIC LIGHT CONTROL SENSOR
CIRCUIT
Disconnect the connector from the sensor and inspect the con-
nector on the wire harness side, as shown in the chart.

spect wire harness side connector from the back side, as
shown.

INSPECTION
1. INSPECT HORN SWITCH
(a) Disconnect the negative (-) terminal from the battery.
(b) Remove the left and right covers from the steering wheel.
(c) Using a torx socket wrench, loosen the 2 bolts.
(d) Pull up the horn pad and place it on the steering column,
as shown.
HINT:
Do not disconnect the connector from the horn pad.
(e) Disconnect the connector from the slip ring.
(f) Check that no continuity exists between terminal 6 of the
connector and body ground.
(g) Check that continuity exists between terminal 6 of the
connector and body ground when the horn contact plate
is pressed against the steering spoke assembly.
If continuity is not as specified, repair or replace the steering
wheel or wire harness as necessary.
(h) Install the horn pad in place and using a torx socket
wrench, torque the 2 bolts.
Torque:
7.1 N´m (72 kgf´cm, 62 in.´lbf)
(i) Install the left and right covers.
(j) Connect the negative (-) terminal to the battery.
2. INSPECT HORN OPERATION
Connect the positive (+) lead from the battery to the terminal
and negative (-) lead to the horn body and check that the horn
blows.
If operation is not as specified, replace the horn.
