Hi friends.
I need to read an MC68HC11A8 from a 8P.14
This ECU is in a Peugeot 406 1.8 from 1996 with Keypad to insert code.
I am not beeing able to read it.
Anyone knows if there is a special way to read it.
Already tried a lot of ways, all pins lifted and nothing, I get TXD error or if I lift pins to get all connections at green I have "device doesnt respond".
A friend here from the forum sent me a clock file to program into the 27c512, I tried it with code keyboard disconnected and after 1 minute I inserted the original one but with no sucess.
Any of you have some experience with this car?
If so, can you please tell me the best procedure to unlock it?
Changing MCU and disconnect keypad or clock file?
Thanks to all.
Best Regards,
Nuno
