VW Golf 4 2001 Siemens 1C0909605A MASK L52H write error:
Used AUTO BAUD RATE, sec bytes and read successfully , But after clearing crash I couldn't write back.
Every time got error in middle of writing. then red again and got only 6 lines changed to FF (but I changed only 5), rest was ok ( with crash ). I tried to make all bin with FF and it write successfully. Bet when trying to load back orig crash or clear , no success http://www.dark-projects.com/forum/images/smilies/frown.png why ?.
I lifter IRQ1, RESET, VDD.
In other forum found that i need to lift only IRQ1. Does there could be my problem ?

My reading looks OK with UPA

So, the procedure is:
Reading the MC68HC08AZ32A
Make it clear
And the just program it?

I have a piece of software that says to me something about "Security Bytes"! Whats that? Do i have to do a modification or something?
