Title: How to read Bosch ME7.5 EEPROM correctly
Post by: subzverb on August 04, 2019, 10:10:11 PM
hello everybody,

I am trying to understand how better to read correct EEPROM dump of Bosch ME7.5.

I see possible 3 ways:
1. resolder ST950403 to my TL866II programmer and read - what I did already and seems to be dump is not correct;
2. try to read it in OBD mode - what I did already and received an error during this procedure;
3. try to read it in boot mode - this way I still didn't try;

can somebody check my dump in attachment and give me advice how to do this better ?

thanks

you suppose that I'm receiving error in OBD reading because of connected dash ?

yes mine does the same thing sometimes, when it does, pull fuse, cycle key, and try it.

You need bootmode to write it back anyway.

Some ECUs whatever you do won't read via OBD. Second problem is with some PCs, on my laptop I cant read via OBD, but on other laptop I can.
Both laptops can read via boot mode. So I always use boot mode.
