APS_w161_gpsAntennaDisconnected
What does APS_w161 mean?
Tesla warning code in the Autopilot System (APS) module. Warns if APS detects that GPS antenna is unplugged APS detects that GPS antenna is unplugged GPS antenna is plugged in correctly Warns if APS detects that Backup Autopilot is unhealthy APS detects Backup Autopilot is unhealthy based on watchdog state or GPIOs Backup Autopilot becomes healthy again BMS has detected that one or more module temperatures exceeds the warning threshold The BMS uses this for specfic exceptions triggered in code, like data exceptions or machine check errors Indicates a BMB reference voltage has continuously been out of bounds Any BMB reference voltage has continuously deviated outside the in-bounds threshold of the nominal voltage All BMB reference voltages continuously remain within the in-bounds threshold of the nominal voltage Other BMB voltage signals will be substituted given the reference voltage is unreliable BMS sees the VCFRONT MIA while not in drive state
