as a general rule, you should ALWAYS pull the eeprom and read off board. Autel programmer not advanced enough to do in circuit but it does on some stuff but have to have 12v power hooked up to the xp400pro. Get a carprog for eeproms and motorola processors.
If you used the XP400 on a pc it gives you more options like voltage change if you drop voltage to read eeprom you probably would be able to read in circuit because your problem might be feedback from board trying to start with higher voltage and your getting data crash.
You are correct on the pc giving you a little more option with the voltage change, and yes if you wake up something on the board it can prevent a read. Although on the pc I have yet to find out or find if it can set up a verification read and write option settings. Without that on the pc version I've become hesitant on using it for reads because it corrupted a read for me one time and I lost data, so that was it for me with the pc version. Thanks for watching
Real deep stuff, nice and informative video. Tanks. A bit way out of my knowledge today, to do. I'm not afraid doing on-bench programing etc, but get of the chip off not destroying them is bit more tricker as I see it (getting older eyes). You do it so fast, and so reliable/professionall. Buyng stuff needed is not the biggest problem. But/so, what was that yellow gunk used 18:30, before desoldering before the rossin?
it is actually just paint. You always want to either take a picture of the chip and its placement and orientation before you remove it and or start any work, or you can make a mark for yourself as to help when placing it back on the board. it will be a bad day when you mix up the orientation.
@@DTEAuto I'm more concerned blewing/burning it up taking too long to desolder. Or maybe being to quick and damage a track etc. But ruin a big legged component - gosh. Getting it right back, I see as no problema. There are also small trainig curcuits, the are great to practice on.
What do you set your hot air station to?? So you don’t ruin the eeprom? I had to do one with harbor freight heat gun once it sucked all I had at the time laying around

The hot air I set to 400C with air speed around 6-7, and solder to 300C
Same issue here with autel on reading eeproms and failing to verify read/write unless I remove eeprom.
Do you have to do checksum before writing to other component ?
on this particular situation no checksum problems
