I have 05 GX, battery draw 150 miliamps, remove ecu-b fuse for bcm draw is gone, put fuse back no draw, open close door draw is back, check all lights, bcm keeps dome raley on all the time, any ideas? swap bcm same problem, turn parking lights on off same draw comes back.

 

Could it be the alarm system ? Remote access ?

 

The problem is not the fuse here, it is the relay, Check out the Positive wiring from the Battery which leads to a Relay ( this needs to be replaced), I do not know the location but this is outside the fuse box, but within the Engine Bay. The relay costs 28/-$.

 

I have load test wiring to the relay .3 voltage drop, swap muntiple releys, I notice if i dont lock the car with factory remote draw is still their, if i lock the car with remote after 30 seconds drops to 50 miliamps, can any one check draw on their car with out locking the vehicle with remote? Let me know thanks.

 

So, let me get this straight. Your body-ecu is keeping your dome light relay on all the time ? Hence keeping your dome light on after you exit and lock the vehicle ?

 

Yes dome light relay stays on if i close all the doors and not lock with remote, dome light will shut off, nothing is staing on I check in pitch dark, gove box not on, no light stay on, if I use remote to lock the car after 45 seconds draw is gone, I will go thru all connectors under dash in left kick pane and will lift carpet to see anithing is hiding under carpet, has to be some corrosion higing in conector.

 

I just checked the following, AFter removal of the key and close the doors the interior dome lights stay for 60 seconds( designed on GX) , Now when you use the remote key to lock the doors the dome light and the courtesy lights all shut off instantly. Now I locked myself in my car, checked the continuity, the Courtesy light and dome lights were having 10V ( in the dark) , Now I inserted the keys to the ignitions started the car. the amp meter showed on the courtesy lights and the dome lights of 12V.

Now when any door is opened the light remains for 15 seconds after the doors are closed and fades out.
If you feel the volt drop is much lesser to the above i have mentioned then you need to look at the body ECU which is located behind the Instrument cluster.

 

I'm not sure if 150 miliamps is worth this much trouble. I think that would be on par with what the computer would draw in stand-by mode. It would be nice to examine wiring diagram first before you dive under the dash and carpeting.

 

FIXED: sunroof tube was leaking in to kick panel connectors, I clean connectors, replaced sunroof tube and no more draw, thank for you help.
