I managed to get myself an old HIM that work with official HDS.
My primary goal is to reset the permanent code of ABS error caused by replacing front brake. Which I have done without a problem. I am now interested in other functionality that this little toy is capable of. I however, dare not to try without proper documentation. May I know if there are any document related to HDS that is obtainable?

There is one on the internet which is specific to HDS tablet. But I found it not very useful as it focus mainly on the tablet operation.

The help function in the HDS is only available when I select the item, and there is no mean that I can access without connecting to my car and access the specific item.

Thanks.
