Hi Guys,
I am attempting to recover a dead Saturn Vue E38 Pcm. I am hoping somebody could help me out with a layout or diagram to connect BDM to attempt to rewrite to flash chip
Thanks
Ziggy

you have to mutilate the ecm to get to the flash chip. It just isnt worth fixing them. The chip adapter needed costs more than the computer anyways if you are only fixing one.

the chip is on the underside but the side of the board you can see is the side you need to put the BDM on... if we can find the pins then it surely is possible to reprogram it.. and i have 2 e40's that i think have corrupted booatloaders...

one died after a 100% write of HPTuners... the other from TIS...

they basically must have the wrong OS in them...

Same here! Hence the search

Bootloaders are deleted after power loss.

As for the wrong os, boot segment combo that is possible. But only on the e40s i think.

yeh well these when you try and read them come back with the error of "please make sure plugged in and switched on"

but the tunes went all the way to 100% on both TIS and HP's

so not sure... but they are brand new .. both of them
