I can't get to the WIS section of the EPC. It asks me for a SA and wants to search it once one is entered. Here are my questions; what is a SA number, or is the WIS for paid subscriptions only? Is the SA number tied into my VIN or something else? :confused:
Many thanks for any and all responses.

You can subscribe for a fee to WIS, but even at that, a non dealership subscription won't be linked to EPC.

In fact I have been told, and have seen, that not all dealeship computers with access to EPC are also linked to WIS.

The SA is apart of the EPC search function----go to EPC help button and you will understand the function.

You should always put you VIN in EPC, then you will get the "blue car" icon. With that icon lite up it will exclude all parts not applicabe to you VIN. It is just a good search aid.

Good luck!!
