Chrysler Repair: Battery going flat (discharging): 02 minivan, chrysler grand voyager, internal colors


Question
QUESTION: Hi Roland

I am in South Africa and have a Chrysler Grand Voyager Limited 3.3L 2002 model. I have problems with the battery going flat in 2-3 days. I connected an ammeter between the battery - and the cable and the reading was 0.3A. I draw the fuses in the PDC one by one. When I draw the 40A fuse marked BCM#2 the reading dropped to 0.09A. If I draw the IOD fuse as well the reading drop to below 0.01A. I have looked for the interior fuses under the dash in the driver's side, but couldn't find them. All I see there is a module with 6 plugs in (P/N P04727074AD) and something else with a lot of wires (P/N P04869458AB).
What accesories is on the BCM#2 fuse.
Thanks in advance for anything helpful.

ANSWER: Hi Johan,
The bcm is indeed under the dash on the driver side, near the outside of the vehicle (I won't use left or right because I can't be certain which 'hand' drive you have; I assume this is an export vehicle, not one that was sold first in the U.S or Canada).  It has 5 plugs arranged vertically. All 5 are black in color, one has only 4 wires, the rest are 34-pin plugs with verying amount of wires used. If you pull the larger plugs from the sockets you will see that they have 4 different internal colors: green/white/gray/black. The circuit diagrams show the power from  bcm fuse #2 arrives on pin #1 of the 4-wire plug, and bcm fuse #1 on pin 5 and the IOD fuse 24 on pin 2 of the 4-wire plug, the last wire is ground.  So pulling that plug will drop the current draw to close to 0 amp. But that doesn't tell us anything, yet.
The diagrams show all the different current outputs from the bcm but don't differentiate whether they come from bcm 1 or bcm 2; IOD of course is hazards and internal lights, memories, etc. that are needed as the van sits. Lets work on the reason for 0.21A being drawn by #2. The .09 is a little high, possibly, but we need to get rid of the .21 first.
Because it isn't clear which devices fuse 1 or 2 powers, I would suggest that you pull each of the 34-pin plugs while monitoring the current and tell me what is the drop for each of them. Ideally we can ID what is powered by the plug that gives the biggest drop and then you can check out those devices. All the outputs are shown by plug and pin number so we should be able to figure this out.

QUESTION: Hi Roland

I forgot to ask if there is some more fuses than those in the PDC next to the battery.

Answer
If there were, they would be in a fuse box under the dash on the left side which was used up to '00. I believe you would have the integrated power module with all of the fuses and relays in that single module under the hood. Unless, of course, they delayed that re-design in the export line, which I doubt. There should be spaces for 33 fuses and 19 relays.
