Do you mean the scan tool is not able to communicate?
scan tool will not show anything,like nothing is there.what is voltage suppose to be on pink wire? will have to get back to you later,as i am at work.
Ignition feed is battery voltage.
i have 12 v at the pink wire,also to the bcm,i have replaced the switch,also have a drain on battery
The drain on the battery should be diagnosed and rectified. It could be related to the BCM logging off. It can be some component not turning off, a bad control module or a relay sticking. The link below should be helpful.
the drain on bat.only starts after the bcm goes out,i have checked everything on car and the only thing that checks bad is the bcm.i would like to know the top 10 things that would make the bcm fry in a matter of minutes.
A shorting in one of the circuits that is linked to the BCM can cause that. The other would be excessive voltage getting to it.
