Now that I have had a look at the ADCM I see that pin 16 has been amputated on the module side and a bypass wire has been sent around it to the left quartile of the case. There it enters the case and some waterproofing gunk has been used to ensure that water does not enter the case.

This is probably the source of my battery drain.

So it looks like I am in the market for an ADCM.

 

You may be in luck. PM me. I believe I have one wiped and clear of codes. Plug and play.

 

How much would you be asking? I am looking at a used one that I can get for around forty dollars Canadian. But your plug and play comment is interesting. Convince me that I should not go for the used one and instead go for yours. I assume that wiping and getting the module clear of codes is fairly expensive.
