When the communication error bit is set by the sensor

Sensor function will be impaired, park assist features will be disabled.

UMC vehicle connector (charge handle) temperature has risen above 75 C

UMC will not allow charging until the charge handle cools sufficiently

UMC input terminal temperature has exceeded 95 C

UMC will not allow charging until input terminals cool sufficiently

UMC smart adapter temperature exceeded 75 C or the smart adapter specific rating if present

UMC will not allow charging until the smart adapter temperature has fallen sufficiently

Proximity line in charge cable has no voltage present but a vehicle is connected

UMC will not allow charging while the proximity line is broken because it cannot determine if the cable is latched

Pilot signal transitioned to an invalid voltage level

UMC will not allow charging while the pilot signal is invalid

UMC was unable to read smart adapter temperature after several retries

UMC will only report 8 A charge current capability until the smart adapter temperature can be determined

GFCI self test failed

UMC will not charge until the self test passes. UMC will retest automatically after 15 minutes (except EU smart adapters) or charge cable cycle

UMC input voltage has risen above 300 V RMS

UMC will not allow charging until AC input voltage is within 90-300 V RMS

A ground fault current exceeding detection threshold was detected

UMC will not charge until the ground fault is corrected. UMC will retest after 15 minutes (except when an EU smart adapters) or charge cable cycle

UMC AC input voltage has fallen below 90 V RMS

UMC will not allow charging until AC input voltage is within 90-300 V RMS

-

UMC contactor is open when it should be closed (non-EU smart adapter) or closed when it should be open for several seconds

UMC will not allow charging if the contactor is stuck in an unexpected state. Charge handle pins may be live and hazardous. Stuck open (non-hazardous) contactors will not trigger this fault with EU smart adapters.

UMC AC input side ground impedance is above 1 Mohm

UMC will not allow charging until the protective earth connection is corrected

-

UMC smart adapter genealogy was read but the data failed an integrity check

UMC will only report 8 A charge current capability until smart adapter genealogy can be read and passes an integrity check

GPU driver reports a fence timeout

Touchscreen or UI may not be responsive

UMC PCB temperature exceeded 100 C

UMC will not allow charging until the PCB cools off sufficiently

The Gateway (GTW) sets the signal GTW_ethGoToSleep=0 after the UI has began preparing for or entering sleep. Alert log signal data should provide more information on the specific condition(s) detected.

The UI may appear to be unresponsive while aborting the sleep attempt.
