HID Lamp System Troubleshooting

1. Check the No. 49 (20 A) or No. 52 (20 A) fuse in the

main under-hood fuse/relay box.

Are the fuses OK?

YES — Go to step 2.

NO — Replace the fuse (s), and recheck.

2. Substitute a known-good HID bulb and recheck.

Does the headlight low beam come on?

YES — Replace the HID bulb.

NO — Go to step 3.

3. Disconnect the 2P connector from the inverter unit.

4. Turn the combination light switch ON.

5. Measure the voltage between the No. 2 terminal of

the inverter unit 2P connector and body ground.
7. Check for continuity between the No. 1 terminal of

the inverter unit 2P connector and body ground.

Is there continuity?

YES — Substitute a known-good inverter, and

recheck. If the symptom/indication goes away,

replace the original inverter unit.

NO — Repair open in the wire between the inverter

unit and body ground. If the wire is OK, check for

poor ground at G202 or G302.ProCarManuals.com
