1) Disconnect the CAN junction connector
(i128) and body integrated unit connector (i84).
2) Measure the resistance between connector
terminals.
Connector & terminal
(i84) No. 26 — (i128) No. 7 to 12:
(i84) No. 27 — (i128) No. 1 to 6:
NOTE:The i128 junction connector is freely arranged.
Is the resistance less than 10
Ω?
Go to step 2.Repair the short
circuit of harness
or replace har-
ness.

A: REMOVAL
1. HIGH BEAM AND LOW BEAM
CAUTION:
•Because the halogen bulb operates at a high
temperature, dirt and oil on the bulb surface re-
duces the bulb's service life. Hold the flange
portion when replacing the bulb. Never touch
the glass portion.
•Do not leave the headlight without a bulb for
a long time. Dust, moisture, etc. entering the
headlight may affect its performance.
1) Disconnect the ground cable from battery.
2) Remove the air intake duct. (When removing the
headlight bulb RH)
3) Remove the battery. (When removing the head-
light bulb LH)
4) Disconnect the harness connector.
5) Remove the bulb assembly (A) then remove the
high beam. To remove the low beam, remove the
back cover (B), and then go to the next step.
6) Remove the light bulb retaining spring (A) to re-
move bulb.
