Vida CEM swapping

[vtl]

Do not power CEM before the cracker. Start the cracker, wait for "Putting all ECUs into programming mode", only then apply power to CEM. You have 5 seconds to do so.

I do not have the "Putting all ECUs into programming mode" message on display or monitor in arduino.

Here's the arduino monitor.

Thanks

it says:

#define CEM_PN_AUTODETECT /* comment out for P2 CEM-L on the bench w/o DIM */

Already done no change

I think there is something wrong with the pin on CEM.

Can it read part number now? Power up Teensy, wait for message, power up CEM within 5 seconds.

No way it can't work on the bench. I spent long months with CEM-L on the bench, hundreds of runs.

I said it works on the bench. I ran it once, maybe twice on a real car Remove autodetect line, compile/upload, wait for the message, power up the CEM quickly.

I just managed to read the PIN on my C30. Can I check the previously read code after unplugging the Teensy and plugging it back in? Is it saved somewhere?
