Red
On
XETK-V2.0 is supplied with power and active (i.e. the ECU is
switched on or the ETAS calibration and development sys-
tem is connected and ready to communicate with the XETK-
V2.0)
Green
On
Power supply has dropped under 4.3V (XETK-V2.0A/C) or
the selected standby threshold (XETK-V2.0B):
- data retention of the calibration data in the XETK-V2.0A/C
SRAM or the ECU RAM monitored by the XETK-V2.0B is no
longer ensured
- as soon as ECU switches on again, it should switch to the
Reference Page.
Green LED stays lit until the calibration and development
system downloads data into the calibration data memory.
Until then switching to the Working Page is not possible.
Off
Working page may be different to reference page. Calibra-
tion and development system has downloaded data since
the last power failure. Switching between the Reference
Page and Working Page is possible.
