Hey there,
The Eeprom chip you are attempting to locate is where there are 2 small 8 pin chips located (if facing the head unit's main center board only from the rear underside up) in the right hand corner of the board toward the front with one chip after another. The security 9355093 chip is the one located closest to the front edge of the board. The writing may not be seeable on the chip. In fact, it is printed so faintly in some cases, it may appear to not be printed on at all. I believe this was for identity protection purposes on Delphi's part, however, instead of hiding the chip, they made it stick out like a sore thumb. Remember that this Eeprom is located on the main board only and not the faceplate.
I hope this clarifies this for you.
By the way, what is this service ceter you sent yours to? Just wondering for reference. Also, take note, with the eeprom installed/replaced, it prevents the unit from being turned on via 12 volt ignition.
Thank you,
Starflare5.

I have a Delco p/n 10315119 w/o tape w/ CD from 2001 MC. I opened the metal "bottom" to acces the 9355093 eprom. I do not see that number on any chip on the main board (6"x9"). There are three eproms on edge w/ heat sink plate. Numbers and size(.25"x.36") do not match. Re-reading your post and nuku's post, is the eprom 9355093 behind the face panel. I removed the face, prying the eight plastic locks loose. There is a board 3"x9" behind the face place held in place by very small screws. That is the only other board I see; also it reflects on the "hr.mn buttons" terminology.
There is a very small (approx .25"x.36") "eprom" on the 6x9 board however it does not notate 9355093.
(Anyone) Please clarify
FYI. I sent a 10335223 to a repair center just before reading the posts. They told me they would replace the eprom with a new one and burn it to fit any GM car. Cost: $50 plus $12 postage. Their refernce to eprom was what led me to search "eprom GM RDS" and find this post. Maybe $62 is cheap for an electronic lesson  |
