Energy management calibration
During energy management calibration A/D-converter, BSI, Btemp, Battery voltage,
Charger voltage and Charger current are calibrated.
Limits for calculated calibration values are as follows:
ADC-offset over limits:
Inspect BSI line and components in it (R385, Pull-up resistor R220). If these are OK,
change UEM.
BSI Gain over limits:
Inspect BSI line and components in it (R385, Pull-up resistor R220). If these are OK,
change UEM.
