Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.
There is a quick type of bypass if the igniton cylinder had failed. This is to get a resistor that matches the value of the pellet in the key, then wire that resistor into the wires that run to the ignition cylinder.
I have tyhe correct resistor and had placed in in a loop between the two white wires that came out of the ignition and taped off the upper two parts, was this correct?
That is, and if that did not work then you have a fault in the BCM itself.
But can I ask how you know the theft is keeping it from running?
after I removed the bypass the car started up and ran, then overnight when I went to start it it acted like it was grounded out.
So you may have the resistor the wrong value then. What value did you get?
#4 for a reading of .887 my resusitor was .891
Ok then you likely have a bad BCM.
I thought so, if I install and replacement do I need to relearn the computer with the key by the 30 minute relearn sequence?
And you will need to have it programmes.
programmed with a scan tool.
where can I get the correct scan tool and proper codes to do this? This is all new to me and I appreciate your expertise.
The scan tool is a dealer or shop item.
And if the shop can do programming then they will have all you need.
I don't want the same occurrence 3 yrs or less down the road, is there any way to just disable the Passlock II VATS and have a normal car?
these one where the TDM is embedded in the Body Control Module and a class 2 system, it is difficult. I know of a system that does it of they are not the class 2, but yours is a class 2.
AlarmTek makes a bypass kit will this work, I'm no electrician, but not rich either..willing to try this product.
Most require the car to be able to start to make it learn the system's codes. If you can get it to start with the key , you may be able to make it work.
