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.

2. Disconnect the 10P (or 12P ) connector (A) from the ambient light (B), then remove the ambient
light from the front individual map light housing (C).
1: ’06-07 models
2: ’08-09 models
3. Connect battery power to the terminal No. 5 and ground to the No. 3 terminal. The ambient light
should turn on. If the light does not turn on, replace
the ambient light.
4. Install the ambient light in the reverse order of removal. 1. Carefully pry off the lens (A) with a small
screwdriver.
2. Pry out the housing (B) from the door panel, then disconnect the 2P connector (C).
3. Separate the housing, then remove the bulb (D) from the socket.
