The incorrect memory capacity is detected upon system boot up
System boots with the incorrect memory capacity.
High system memory usage may lead to degraded Infotainment performance or frequent system reboots.
UMC ADC self test: reading did not pass sanity check
UMC microcontroller analog readings fail sanity checks
UMC will not operate until ADC readings pass sanity checks
Universal Mobile Connector (UMC) AC input side ground impedance exceeded threshold
UMC AC input side ground impedance is above 1 Mohm
UMC logs that high ground impedance is detected, charging is still allowed.
UMC microcontroller failed internal data bus self test
UMC microcontroller fails internal data bus self test
UMC will not operate until internal data bus passes self test
UMC microcontroller RAM failed self test
UMC microcontroller fails RAM self test
UMC will not operate until internal RAM self test passes
UMC vehicle connector (charge handle) temperature is causing output current reduction
UMC vehicle connecter temperature has exceeded 65 C
UMC will reduce reported current capability by half until the vehicle connecter cools sufficiently
UMC input terminal temperature is causing output current reduction
UMC input terminal temperature has exceeded 85 C
UMC will reduce reported current capability by half until the input terminals cool sufficiently
UMC application memory did not match expected CRC
UMC application memory fails integrity check
UMC will not operate until application memory passes an integrity check
Timeout while UMC attempted to read smart adapter temperature
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
UMC read smart adapter genealogy data and CRC check failed
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
UMC proximity line disconnected or vehicle is not providing proximity voltage
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
UMC pilot signal is being pulled to an invalid level or pilot generation circuit failure
Pilot signal transitioned to an invalid voltage level
UMC will not allow charging while the pilot signal is invalid
Timeout while UMC was attempting to communicate with smart adapter
UMC was unable to read smart adapter genealogy after several retries
UMC will only report 8 A charge current capability until the smart adapter genealogy can be read
UMC PCBA temperature is causing output current reduction
UMC PCBA temperature has risen above 90 C
UMC will reduce reported current capability by half until the PCBA cools sufficiently
UMC detected contactor stuck open or closed
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.
