I am trying to solve a key off battery drain. I have pulled all of the fuses and the alternator cable to the battery with no reduction in the amperage draw. I started to disconnect some of the connectors to see if I could isolate the area that had the draw. Well, when I disconnected C238, on the driver firewall(the large connector with the bolt) the draw went down to 1 amp from the 3.3 amps that I saw. I have an old (2006) tech cd(05-06 ISO) and been trying to track down all of the circuits. I have been able to find very few circuits. I am hoping to find a diagram that will have names attached to each circuit e.g. circuit 1435(DG-VT). what is it for? There are 66 pins in the connector.

Thanks.

 

If it's a 66 pin connector it's a major body harness that has basically the whole interior circuits run through it.


It is usually recommended to start pulling fuses individually from the fuse box (engine bay and interior) and see what causes the drain to be reduced. Then you can look at circuit diagrams that include the fuse and go from there

I have a factory wiring manual in 'searchable' PDF format (although for a 2005) that might shed some light on it issue. I searched it for "C238" and got several hits. Check your private email - where I have sent you a link to download it.


Maybe this will help.

 

c238. Subwoofer and amplifier

 

His battery is probably long dead by now, that was three years ago.
