How do I change the VIN on some new to me Blis modules using Forscan? I have my VIN to Hex numbers, just don't know how to input them. Also, this is a new to the truck blis add on.

Shows that there are VIN specific values, but what gets input on those and in what order?

 

Convert each character to Hexadecimal equivalent. Each hex value will be two characters. For example, VIN character "1" is hex "31". VIN characters 1 through 5 go in PID address 7C4-08-01 (SODL) or 7C6-08-01 (SODR). The 6th character gets put in 7C4-08-02 or 7C6-08-02. Characters 7 through 11 in 7C4-09-01 or 7C6-09-01. Charcter 12 in 7C4-09-02 or 7C6-09-02. The last five characters, 13 through 17 in 7C4-10-01 or 7C6-10-01. The last two characters in each As-built PID line are checksums and just let FORScan calculate and enter them.

See Post 4 of this thread for how to use FORScan.

If you really wa nt to calculate the checksum, the attached Excel spreadsheet does this.

 

ok, so my 31 46 54 46 57 31 45 46 36 48 46 41 37 37 33 37 37 should be input as:

7C4-08-01 3146 5446 57??
7C4-08-02 31??
7C4-09-01 4546 3648 46??
7C4-09-02 41??
7C4-10-01 3737 3337 37??

Correct?
Just leave where I put the '?' as blank?

 

You got it.

 

Excellent! Thanks!! I'll try it tonight.

 

You will get a message like this. Select "Yes" and FORScan fills them in for you.

 

That what it gave me when I changed to DDM and PDM to X4XX XX My '4' was a zero. Still doesn't work, but I'll fix the VIN issue first I think.

 

Seems the problem I'm seeing now is that on a couple lines of data, I have extra blocks to fill in. Like 7C4-02-02 shows 2 entries on the forum page from above, and mine has 3 blocks to enter info. I tried leaving them blank, but it doesn't like that. Now what?
Also, the Blis mods are from a 2019 per the VIN. Mine's a 2017. Is that the issue?
