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.

4. Inspect the connector and socket terminals to be sure they are all making good contact.
 If the terminals are bent, loose or corroded, repair them as necessary and recheck the system.

5. With the connector still disconnected, 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, go to step 6.

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.

5. If necessary, open the hood and adjust the
headlights to local requirements by turning the
adjusters (A). 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.
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.
1. Remove the front bumper (see page 20-146).
2. Remove the connectors (A) from the headlight assembly (B).
3. Remove the five bolts, then remove the headlight.
4. Remove the bolt (C) and the corner upper beam (D) from the headlight.
5. Install the headlight in the reverse order of removal.
6. After replacement, adjust the headlight to local requirements.

When entering the self-diagnostic mode, the following indicators blink:
A/T gear position indicator, ABS indicator, brake system indicator, charging system indicator, cruise control indicator,
cruise main indicator, door indicator, DRL indicator, EPS indicator, fog light indicator , high beam indicator,
immobilizer indicator, lights-on indicator, low fuel indicator, low oil pressure indicator, low tire pressure indicator ,

1: ’07 TYPE S and ’08-09 models
2: ’08-09 models
3: TYPE S and ’08 Premium and ’09 models
At the initial stage of the self-diagnostic function, the beep sounds intermittently, the beeper sounds continuously
when any of the following switch inputs are switched from OFF to ON:
Cruise control main, dash lights brightness controller volume ( ), ( ) button, mph km/h switch, parking brake switch,
SEL/RESET switch, SET, RESUME, CANCEL switches, and VSA OFF switch . : ’07 TYPE S and ’08-09 models
When entering the self-diagnostic mode, the beeper sounds five times.
When entering the self-diagnostic mode, all the segments blink five times.
When entering the self-diagnostic mode, the tachometer needle sweeps from the minimum position to maximum
position, then returns to the minimum position.
NOTE:
After the beeper stops sounding and the gauge needle returns to the minimum position, pushing the SEL/RESET
switch starts the Beeper Drive Circuit Check (one beep) and the Gauge Drive Circuit Check again.
The check cannot be started again until the gauge needle returns to the minimum position.
If the needle fails to sweep, or the beeper does not sound, replace the gauge control module (tach).
