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).

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).

NOTE: If you are troubleshooting multiple DTCs, be
sure to follow the instructions in B-CAN System
Diagnosis Test Mode A (see page 22-93).
1. Clear the DTCs using the HDS.
2. Turn the ignition switch to LOCK (0), and then back to ON (II).
3. Start and run the engine for at least 5 seconds then turn the engine off.
4. Check for DTCs with the HDS.
Go to step 5.
Intermittent failure, the F-CAN
communication line is OK at this time. Check for
loose or poor connections. If the connections are
good, check the battery condition (see page 22-67),
and the charging system.
5. Check for DTCs in the ECM/PCM or ABS/VSA.
Troubleshoot the ECM/PCM or ABS/VSA.
Go to step 6. 6. Do the Gauge Control Module (Tach) Input Test
(see page 22-271).
Go to step 7.
Repair the faulty input then recheck for
DTCs.
7. Substitute a known-good gauge control module (tach).
8. Clear the DTCs with the HDS.
9. Turn the ignition switch to LOCK (0), and then back to ON (II).
10. Start and run the engine for at least 5 seconds then turn the engine off.
11. Check for DTCs with the HDS.
Substitute a known-good ECM/PCM and
retest. If the system/indication goes away, replace
the original ECM/PCM.
The original gauge control module (tach) is
faulty; replace the gauge control module (tach)
(see page 22-277).
