Error DSAB : PRIMARY OAT SENSOR LOST ???

This means that the OAT is not being seen by your system. But the exact connection to chase down cause depends on your exact system configuration. A few questions:

Has OAT ever worked?
Do you know whether you have OAT connected through your EMS or through your EFIS's EDC?
