1. Remove the steering column covers (see page
17-9).
2. Disconnect the cable reel 20P connector (A) from the dashboard wire harness.
3. Using a jumper wire, connect dashboard wire harness 20P connector terminal No. 10 to body
ground. The horn should sound.
 If the horn sounds, go to step 4.
 If the horn does not sound, check these items: – No. 12 (15 A) fuse in the under-hood fuse/relay box.
– MICU.
– Horn.
– Anopeninthewire. 4. Reconnect the cable reel 20P connector (A) to the
dashboard wire harness.
5. Remove the driver’s airbag assembly (see page 24-188), and disconnect the horn switch 1P positive
terminal (B) from the cable reel (C).
6. Using a jumper wire, connect the 1P connector to body ground.
 If the horn sounds, replace the driver’s airbag assembly.
 If the horn does not sound, check these items: – Cable reel.
– Anopeninthewire.

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.

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.

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.
