Efi live from atp auto cal not working
Error code $0537
From our error code list.
**
$0537 Controller is locked with a custom key.
An attempt was made to read or program a controller that cannot be unlocked using the standard GM keys.
If you know the key that was used to lock the controller, please use the unlock option in the EFILive software to unlock the controller before attempting to read or re-flash the controller again.
**
Has the ecm been tuned previously?

I believe the ecm was previously tuned because there was loose wires hanging off it bought it from the dealership can I bring it back to them and have them flash/ unlock it
The dealership will not be able to unlock it either.
There is probably a few people that can unlock ECM's, I can say that these guys do them but you do need to send your ECM to them.

Can they flash it back will that unlock it
The answer to your question depends on how the controller was originally locked.
If the controller was locked using EFILive's Auto-locking feature, then a full flash (which you could do) would unlock the controller. Did you attempt to read or flash the controller to get your $0537?
If the controller was manually locked using a custom key, flashing over the top will not be sucessful. If manual locking was used, then there are 2 possible scenarios:
If the key is generated by the tuner, and the tuner provides you the key you will be able to unlock the controller using that key.
If the key is generated by FlashScan, then only FlashScan devices with the same License Number can be used to unlock the controller.
If the controller is manually locked, and you either don't have the key, or know who's FlashScan was used to originally flash your ECM, your only option is a someone like wait4me (detailed earlier in this thread) who can use "brute force" to unlock the ECM.

I tried reading it and flashing it and still got the same results.
Can I get a reman ecm and have it flashed to the truck then upload my tunes that way can't be without my truck need it for work daily
If I bring it to the dealership and try a full flash what are the chances they fry my ecm
Yes you can do that.Quote:

It wouldn't lock because my airbag sensor went right just wanted to double check before I started looking for a new ecm
If you had a communications error because of something interferring on the can bus, or because something was mechanically unsound you would not be getting an error code that detailed the ECM was locked.Quote:

We have ecms that i can load your tuning onto and send it. Call for the costs. Most likely your ecm will be a repairable core but i can put it on the bench harness and see what is up with it.
Could it be a software update issue if my trucks software is out of date or if the efi live software is out of date
You'd have had a different error if your software was out of date. $0537 is controller is locked with custom key.Quote:
