|
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.
