UMC_w012_pilotFault
|
|
-
|
|
|
UMC vehicle connector exceeded temperature threshold.
|
UMC vehicle connector (charge handle) temperature has risen above 75 C
|
UMC will not allow charging until the charge handle cools sufficiently
|
|
|
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 input terminals (UMC side of smart adapter connection) exceeded temperature threshold.
|
UMC input terminal temperature has exceeded 95 C
|
UMC will not allow charging until input terminals cool sufficiently
|
|
|
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 AC input voltage is below lower limit.
|
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 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.
|
|
|
UMC AC input voltage exceeded upper limit.
|
UMC input voltage has risen above 300 V RMS
|
UMC will not allow charging until AC input voltage is within 90-300 V RMS
|
|
|
UMC PCB temperature exceeded threshold.
|
UMC PCB temperature exceeded 100 C
|
UMC will not allow charging until the PCB cools off sufficiently
|
|
|
UMC_w020_applicationCRC
|
|
-
|
|
|
UMC ground leakage current exceeded threshold.
|
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 GFCI self test failed.
|
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 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 wall plug (smart adapter) exceeded temperature threshold.
|
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
|
|
|
Infotainment process hung for extended period of time.
|
Operating System reports a task was hung for 2 minutes
|
Touchscreen or UI may not be responsive
|
|
|
Infotainment GPU operation timed out.
|
GPU driver reports a fence timeout
|
Touchscreen or UI may not be responsive
|
|
|
Infotainment process stopped unexpectedly.
|
Operating System reports a segmentation fault
|
Application or UI element closes or restarts
|

|
|
The cellular baseband Radio Frequency (RF) module did not initialize.
|
The cellular baseband RF module reported a condition affecting its operation while in online mode.
|
Vehicle loses cellular connectivity. This affects features reliant on network communication.
