Answers :

BCM/ECM are very sensitive components in gm systems ..especially cadillac. I would leave the ECM alone . If you want to by pass the vats portion of the system simply buy a bypass system...they are still around and simple to install. some simply use a component to wire into the two wire resister circuit where you put the proper resistor into the component module before you wire it in ...There was others where you put a spare key into the module box and it just reads the pellet straight from the key ..thus by passing a faulty ignition module key way problem.
Vats can be bypassed by locating wires from key lock cylinder under dash. this is common problem with this type of system. you must determine resistence valu of key resister and cut wires ind solder replacement to ends of wires that go to vats module which is seperate from ecm module.
