If there are 2 or more part numbers for one part on your Toyota diagram, marked with a ※ (the x with dots means reference mark), look for a legend to explain further. Sometimes it’s on the next page. Different trim levels and equipment specification are fitted with different parts, usually this is made clear in the legend or part name.
However, sometimes you find something like this:
… Without an accompanying explanation. At first I thought it was a range of chassis numbers, but they’re actually date codes in the form YYMM. I don’t know how Toyota aligns the change over, so ask your parts guy if you need to.
It took me a little while to figure out, so now you know.
