FETK-T3.0 is supplied with power and active (i.e. the ECU
is switched on or the ETAS calibration and development
system is connected and ready to communicate with the
FETK-T3.0)
Green

Working Page contains data and is accessible from INCA
Flashing FETK-T3.0 is in boot configuration mode:
- measurement and calibration are not possible,
- FETK-T3.0 update with HSP is required

Power supply has dropped under selected threshold:
- data retention of the calibration data manager in the ECU
is no longer ensured
- as soon as the FETK-T3.0 switches on again, the ECU
switches to the Reference Page.
Green LED stays lit until the calibration and development
system downloads data into the calibration data memory.
Otherwise switching to the Working Page is not possible.
