Anyone have any experience with a 2003 supercab fx4 4wheel disc brakes having battery drain with key off. Been pulling the the #15 interior fuse to keep battery from draining when parked.

# 15, 5 amp fuse feeds stop lamp switch (speed control,brake shift interlock), GEM, Rear Anti Lock Brake system, (RABS) module.

I have previously had the GEM out of the truck last year with similar problems......it did NOT look damaged from water and was not corroded in any way. I put it back in and all was well up until last week. Battery drain came back.

I also have had the ABS light on my dash for a while now. Could the problem be with the RABS module?

I have looked all evening on the web and there just isnt alot of info on locating the items to test/unplug.

I read there should be a connector on the passenger side kick panel to use to check abs code but im not having any luck finding it. Ive looked high and low and am not seeing it. Could the abs codes be read with a scanner on this 2003?


Thanks in advance

Also, i have had a dmm between the - battery post and cable. Its showing a 2 amp draw with #15 fuse pushed in and truck asleep. I pull the fuse and it drops to 20 ma which i believe would be acceptable.

i have also unplugged the rear abs sensor with no change. I put a meter on it and showed 1847 ohms so i believe its good....

im just looking for advice on where to locate the other items to unplug and test

Will give that a try.
anyone have advice on pulling abs codes??????

i pulled the switch on the master cylinder and it was wet. Im assuming it is supposed to be????
everything concerning it looked ok.

Im starting to wonder if it isnt GEM/fuse panel related......i noticed my interior lights,door dinger, and rear cargo lights work part of the time the door is open
