I have a Haynes manual, but for code 52 it only has one listing and it says:
52 (5.7L Chevy Engines)....CALPAK error.....check installation. if OK ECM may be faulty.

But it doesn't show anything for the HT4100 engine (4.1L). Can anyone tell me what that error means for the HT4100 engine??

Code 52 is ECM Memory reset... It's telling you that you disconnected the battery.

Is it anything to worry about?? How do you clear code 52?

It means nothing other than the ECM was reset when the battery was disconnected. Clearing it will cause Code 52 to come up again, so there is nothing you can do. It's not damaging anything and is not causing any of your problems.

It will go away after a pre-determined number of key cycles where no codes have been set. I want to say ten, but that is OTOH...
