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.

6. Reconnect the connectors to the under-dash fuse/relay box, and do these input tests at the following connectors.
 If any test indicates a problem, find and correct the cause, then recheck the system.
 If all the input tests prove OK, the MICU must be faulty; replace the under-dash fuse/relay box.

HID Lamp System Troubleshooting
A
B
A transient high tension (25,000 V) occurs at the
bulb sockets or 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 headlights 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 unit.
 Do not turn on the HID bulb by using a power source other than the battery mounted on your
vehicle.
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.

16. Measure the voltage between the HID unit 2P
connector terminal No. 2 and body ground.
Substitute a known-good HID unit, and
recheck. If the symptom/indication goes away,
replace the original HID unit.
Go to step 17.
17. Disconnect under-dash fuse/relay box connector G (21P) and/or F (34P) .1: Left headlight
2: Right headlight 18. Check for continuity between under-dash fuse/relay
box G (21P) terminal No. 17 or F (34P) terminal
No. 4 and HID unit 2P connector terminal No. 2.
Replace the under-dash fuse/relay box.
Repair an open in the wire between the
under-hood fuse/relay box and the HID unit.
