11. Check the No. 12, No. 13, and No. 18 fuses in theunder-dash fuse/relay box.
Go to step 12.
Replace the blown fuse and recheck. If the
No. 18 (20 A) fuse is blown again, replace the
under-dash fuse/relay box. If the No. 12 (10 A) or
No. 13 (10 A) fuse is blown again, repair a short in
the wire between the under-dash fuse/relay box
and appropriate headlight (high beam).
12. Check the headlight bulbs.
Go to step 13.
Replace the faulty bulb.
13. Disconnect under-dash fuse/relay box connectors F (34P) and G (21P).
14. Disconnect the both headlight (high beam) 2P connectors.
15. Check for continuity between right headlight (high beam) 2P connector terminal No. 2 and under-dash
fuse/relay box connector F (34P) terminal No. 22.
Go to step 16.
Repair an open in the wire between the right
headlight (high beam) and the under-dash fuse/
relay box. 16. Check for continuity between left headlight (high
beam) 2P connector terminal No. 2 and under-dash
fuse/relay box connector G (21P) terminal No. 15.
Go to step 17.
Repair an open in the wire between the left
headlight (high beam) and the under-dash fuse/
relay box.
17. Check for continuity between headlight (high beam) 2P connector terminal No. 1 and body
ground.
Faulty MICU; replace the under-dash fuse/
relay box (see page 22-66).
Repair an open in the BLK wire or poor
ground (G 201-right side, G301-left side).

NOTE:
 The MICU turns on the headlights (high beams) in a dimming mode for the Daytime Running Lights under the following conditions:
– With the ignition switch turned to ON (II)
– The headlight switch OFF
– The parking brake is released (parking brake switch OFF)
 The DRL indicator will come on when one of the headlight (high beams) bulbs is blown, or if the high beam wiring has an open circuit with the daytime running lights ON.
 If the vehicle is equipped with an optional remote control engine start system, the daytime running lights will not function when started with the remote start.
1. Before testing the lighting system, troubleshoot the system using B-CAN System Diagnosis Test Mode A (see page 22-93).
2. Check the No. 12 (10 A), No. 13 (10 A), No. 15 (7.5 A), No. 16 (15 A) , (10 A) , No. 17 (15 A) , (10 A) , No. 18 (20 A), No. 19 (15 A), No. 21 (30 A) , (20 A) , and No. 37 (7.5 A) fuses in the under-dash fuse/relay box. If any fuse
is blown, replace it and go to step 3.
1: With HID
2: Without HID
3. Disconnect under-dash fuse/relay box connectors E, F, G, S, and T. NOTE: All connector views are shown from wire side of female terminals.

HID Bulb Replacement
A
C B A
A transient high tension (25,000 V) occurs at the
bulb sockets of the high intensity discharge (HID)
lamps when the combination light switch is turned
ON. It may cause serious electrical shock or
electrocution if you do not observe the cautions.
 Never turn on the combination light switch before fitting the HID bulbs to their bulb sockets
and completing the reassembly of the headlight
assembly.
 Do not service the headlight assembly in wet conditions, such as rain or snow, near a sprinkler
system, or when your hands are wet to prevent
electrocution.
 Do not touch the surface of the HID bulbs with your bare hands and do not stain it with any oils
and fats.
 Do not disassemble the inverter unit and the igniter fats.
 Do not turn on the HID bulb by using a power source other than the battery mounted on your
vehicle.
1. Turn the combination light switch OFF.
2. Do the battery terminal disconnection procedure (see page 22-68).
3. Remove the battery. (left side bulb) 4. Turn the cover (A) 45 ° counterclockwise to remove
it from the headlight assembly.
5. Turn the socket (A) 45 ° counterclockwise to remove it from the bulb (B).
6. Pull the retaining spring (C) away from the bulb then remove the bulb.
7. Install the new bulb in the reverse order of removal. Make sure the notches in the bulb align with the
tabs in the headlight.
8. Install the parts in the reverse order of removal.
9. Do the battery terminal reconnection procedure (see page 22-68).

HID bulb test light 07AAJ-S3MA100
NOTE: Before troubleshooting the HID Lamp System,
do the multiplex integrated control system
troubleshooting using B-CAN System Diagnosis Test
Mode A (see page 22-93). 1. Check the No. 16 (15 A), No. 17 (15 A), and No. 21 (30 A) fuses in the under-dash fuse/relay box.
Go to step 2.
Replace the fuse(s), and recheck.
2. Turn the combination light switch OFF.
3. Do the battery terminal disconnection procedure (see page 22-68). 4. Remove the socket from the HID bulb (see page
22-168).
5. Check for corrosion (A) and traces of electrical arcing (B) at the socket mating part.
Go to step 7.
Replace the socket, and recheck.
