TROUBLE DIAGNOSIS
Trouble Diagnosis without CONSULT-IIEHS000OA
DIAGNOSTIC PROCEDURE 4
CAUTION:
SRS will not enter diagnosis mode if no malfunction is detected in user mode.
1. Turn ignition switch ON.
2. After “AIR BAG” warning lamp lights for 7 seconds, turn ignition switch OFF within 1 second.
3. Wait more than 3 seconds.
4. Repeat the steps 1 to 3 two times.
5. Turn ignition switch ON.
6. Compare the number of flashes to Air Bag Warning Lamp Flash Code.
7. Turn the ignition switch OFF, and disconnect both battery cables.
8. Repair the system as outlined by the “REPAIR ORDER” in “Warning Lamp Flash Code Chart” that corre-
sponds to flash code.
9. After the repairing of malfunction, connect both battery cables, and turn the ignition switch ON.
10. Check that no malfunction is detected.

WARNING:
Xenon headlamp has a high-tension current generating area. Be extremely careful when removing
and installing. Be certain to disconnect battery negative cable prior to removing or installing.
When xenon headlamp is lit, never touch harness (covered with red or amber insulation), bulb
itself or bulb socket with your bare hands
Never service a xenon headlamp with wet hands.
When checking body side harness with a circuit tester, be certain to disconnect harness connec-
tor from xenon headlamp.
When xenon headlamp is lit, xenon bulb must be installed in headlamp housing. (Never turn on
xenon headlamp, if bulb is out of headlamp housing.)
CAUTION:
Make sure to install bulb securely; if xenon bulb is improperly installed in its socket, high-tension cur-
rent leaks occur. This may lead to a melted bulb and/or bulb socket.
Symptom Possible cause Repair order

4. HID relay RH circuit1. Check 15A fuse (No.41, located in fuse and fusible link
box).
2. Check 20A fuse (No. 51, located in fuse and fusible link
box). Verify battery positive voltage is present at terminal
5 of HID relay RH.
3. Check HID relay RH.
LH high beam does not operate, but
LH low beam operates.1. Bulb
2. Open in high beam LH circuit
3. Lighting switch
4. Headlamp LH ground circuit1. Check bulb.
2. Check the following.
–Harness between headlamp LH and lighting switch for
open circuit.
3. Check lighting switch.
4. Check harness between headlamp LH and ground.
LH low beam does not operate, but
LH high beam operates.1. 20A fuse
2. HID relay LH
3. Open in LH low beam circuit
4. LH low beam ground circuit
5. Xenon bulb
6. HID control unit1. Check 20A fuse (No52, located in fuse and fusible link
box). Verify battery positive voltage is present at terminal
5 of HID relay LH.
2. Check HID relay LH.
3. Check harness between HID relay LH terminal 3 and
headlamp LH terminal 2 for an open circuit.
4. Check harness between headlamp LH and ground.
5. Replace xenon bulb with other side bulb or new one. (If
headlamps illuminate correctly, replace bulb.)
6. Replace HID control unit with other side control unit or
