300 CE 1991 - M104 - CA model - Fault code table?

[StephFR]

After troubleshooting for different issues, I've got the Check Engine light ON and a numbers of fault codes in the system.
Most of them due to unplugging with engine ON while troubleshooting (nothing before...).

So I've got the chance to have a CA model where the LED is on the connector, but I don't have the code table.

Where can I found it for this model?

I got codes (# of blinking): 3, 9, 22 and 34.

I found 3 and 9 on such cars are coolant temp sensor and EHA (which I both disconnected), please confirm?
What about 22 and 34?

Thanks,
