Hi. Is there a way someone can help me out with this mcu? My xprog won't read it. I am thinking that maybe the pinout is not correct. Can you guys supply me with a good pinout for this thing? The mcu is out of PCB. The key wont turn and i am trying to Read and then maybe fix it, with someones help. Thnx in advance.

Red light on new key when put in ignition?

[dd1]

No. And I read the key. It has 2 keys. One of them is brand new even

Immo in mirror or not? And car locks/unlocks via key press? Flash data is unlikely to be bad. Does the steering unlock when key is inserted?

EIS talks to ESL and engine ECU. I'm not 100% but may need ESL to be good first before allowing key to turn.

Read fault codes first I suggest

Hi everyone. I have plugged in the Eis and read the codes, none. I manually opened the esl, to the open position. As soon as I put the key in, it looks the esl. And the car has 2 keys, one new and one old. I read both keys with IR and it sees both of them. What's my next step? No one saw anything wrong with the MCUs?
