OBD1 do not have P codes like OBD2. Ask sdash.

I will try asking sdash.
Didn't yet cought the error with smanager, next time (hope not) I will not turn off car.

Thank you for the help.

I think I can see what is happening. If sdash uses Bluetooth then the s300 emulates P error codes over BT.

I would use smanager to see if there are any error codes.

Yes, that's what I will try to do next time.
I can't turn off car next time engine light happer.
If I turn off car engine light goes away, and don't come back anytime soon(last time was 2 months ago).

On Smanager no error codes recorded.
I will put laptop on car and wait.
