Coil failure because of SID swap?

[gschreiber73]

(My post title says SID, but I found out it's the CIM) I recently lost my last key to my 2004 95 ARC with only 56K miles on it. I ended up shelling out $1,700 to the local dealer to replace the CIM and cut two new keys. After 2 weeks and 2 tries (the first CIM being faulty apparently), I got my car back. They day I picked it up, I jumped in only to see a 'security alarm failure - contact dealer' message on the SID. I had to get to work so I left and planned on getting it back the next day. I needed to get it smog checked on my lunch break, which it failed because, as I was told, the computer was not set properly (two of the electronics categories failed). Immediately after that the check engine light came on. Now, after the dealer has looked at it, they tell me there is a coil failure which will need to be fixed to the tune of $600. I have never had any issues with this car until now. Could the CIM swap, and incorrectly setting it up cause a coil failure? I need to know because they are saying it has nothing to do with what they did, though the timing is extremely suspicious.
Thanks in advance.

You can buy the ignition discharge module (DIC) for under $300 and install it in 5 minutes.
Did the dealer tell you what the codes are?

It sounds like it's just an unfortunate coincidence. The "coils" on these cars are more commonly referred to as "DI Cassettes." Also known as DIC, IDM... whatever. You can get a new one for ~$290 and install it yourself VERY easily. On my 2004 it failed at 34k miles.



I made a little video a while back showing how it's done.

That doesn't really answer my question. I'm not going to pay even $300 if it was a faulty CIM or improper installation that caused the coil failure. I am wondering if it is possible for the CIM swap could cause a coil failure.

If that wasn't clear enough for you...

NO. A CIM* replacement cannot cause the DI cassette to fail.

*I have never heard "CIM" as an acronym related to Saab. What did they tell you it stood for? In Saab language, when you lose your keys, the "TWICE" module is replaced. TWICE = Theft Warning Integrated Control Electronics. I think.

I will second that.

Totally unrelated parts of the car.
There is no way that any work done replacing your TWICE unit would have caused a problem with the DI.
As a matter of fact, I can't think of anything you can intentionally do that will cause a DI to fail.
