BMW EWS - How to read OD46J without desoldering

[Sir Pommes]

Hi,

i want to make a full dump (not only the 512bytes eprom) from a EWS3 MCU (0D46J) without desoldering the mcu.
A PLCC test clip should be good enough to establish the connection to the programmer.
But what about the connections on the board, i think i have to cut some wires on the pcb to get full access to the mcu, right?

Can somebody help?

Can confirm because did one yesterday and it works 100%. Can lock old /lost keys and program new key without removing anything.

Hi,

just to make it clear, i want to read the full dump not only the Eeprom.
I have Xprog here, is there any way to read the full dump with Xprog or only with UPA?

I just found out that the ROM can only be programmed during manufacturing, so copying from one hc11 to another hc11 is not possible.

Hi, without doubt use x prog with adapter, a 2 minuts job!
