File in post #1 is bad read.

[mickko]

i have read the dump again.I need timer reset.Thanks

[Zann]

Files in post #1 and post #7 are identical, both are bad.
Maybe there is some bad contact, maybe eeprom is damaged.
If you reading with clip, try to desolder eeprom from board and read directly.

Hi Zann.I read eprom again with a different programmer.The eprom is a m95256w but the other programmer has only m95128w listed.It did read most of it.One quick question ,what part of dump is corrupt.Thanks.

[Zann]

what part of dump is corrupt.

It has too many errors. One of them is this. At address 4E6h there should be text /T23J
Is radio working? What is on the display?

[mickko]

It just says wait i have been told

[Zann]

It just says wait i have been told

If you know correct code, it is better to wait 1 hour, with ignition to ON and then enter the code.
If you try to write different data to eeprom, there is big risk that radio will never start.

Are you sure you read the eeprom from RADIO unit ? Not navi, not CD, not any !

This dump is fine and normal but you need to read nec to get the values to know how many steps back the counter needs resetting mate.
