Hi, I have a strange problem with my accent GSI 2002. My dash
trunk open light and my trunk lamp are always on. But the strange
part
is that vwhen I press the break. The both lamp goes off. If I release
the break the lamp goes on again. I check the schematic there is no
conection with the break circuit. I mesure the voltage at the lamp
and
I mesure that: power side 12V, gnd side 0.7V or 12 V when break is
press. I took the mesurement at the dash lamp. I also take mesurement
at the trunk lamp and here the result: Wire orange/ black
12.5 V with or without break (lamp unplug) wire Green/orange without
break : 0.1V with break 10.9V. I hope someone will able to help me
with
that info.

Thank you
 
Check your room lamp fuse in the underhood fuse box. It's possible that
power may backfeed from elxewhere if this fuse is blown. If your dome
lamp doesn't work properly, that's a very good indicator that this fuse is
probably blown.

Unplug your liftgate latch. If the condition continues, you've just
verified that it has nothing to do with the liftgate switch.

Next, unplug the ETACM (electronic time and alarm control module). If the
problem goes away, you know that the issue is due to the lamps grounding
through the ETACM. If that's the case, go back and verify that all the
fuses that feed the ETACM are in proper working order. If so, you should
next check the ETACM ground G04 behind the left kick panel.
