Signal Name Description Condition Impact
A large voltage drop is detected in the input power to the vehicle controller, indicating the resistance on the input power feed to the vehicle controller is higher than expected.
Estimated resistance on the input power feed to the vehicle controller is higher than expected.
The vehicle controller may be unavailable due to lack of adequate input power, limiting vehicle functionality or making the vehicle inoperable, with at least one other alert specific to that condition present.
A condition affecting switch functionality has been detected.
A condition is detected affecting switch functionality. Alert log signal data should provide more information on the switch affected and specific condition.
The switch may not function or may not function as expected.
Motor current was higher than expected.
Motor current measurement, with calibration offset subtracted, was higher than 17 amps.
Caliper motor or harness may be damaged
The Low Voltage (LV) battery internal resistance indicates degradation is present. Replacing the battery during service is recommended to prevent a future service visit.
Direct Current Resistance (DCR) measurement of the LV battery's internal resistance reports a higher value than expected.
The LV battery internal resistance may degrade to a point requiring replacement. If this happens, then an alert will set indicating LV battery replacement is needed.
The low voltage battery management system (LVBMS) reports the low voltage (LV) battery's internal protection transistor (MOSFET) has opened and it is not recoverable by any device.
The LVBMS reports to the vehicle controller that the LV battery is not recoverable due to any of the following conditions: depleted LV battery state of charge (SoC) due to deep discharge; one or more cell voltage(s) at less than its threshold; the sum of all cell voltages is less than its threshold.
The LV battery is not recoverable by any device.
The front vehicle controller (VCFRONT) controller detects an air lock in the pump due to smaller than expected pump current values.
The pump current is below the minimum threshold value for more than 20 seconds.
Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.
The LV system power or protection are compromised, driving is not recommended.
The LV system power or protection are compromised
Driving is not recommended when LV system is not healthy
Motor current was lower than expected.
Motor current measurement, with calibration offset subtracted, was lower than 0.25 amps
Caliper could be disconnected or the harness is damaged.
The front vehicle controller (VCFRONT) detects a condition affecting the functionality of the right headlight.
The voltage measured across the boost rail, high beam, low beam, DRL, Side Marker, or Turn LEDs is out of range, or the LED drivers in the ECU have reported status flags, or certain values programmed in the headlamp EEPROM are out of range.
Some headlight functions may be unavailable or may not function as expected. Headlight functionality may return after vehicle sleep.
One or more of the messages the vehicle controller receives periodically from the right second row seat controller (VCSEAT2R) is not received, indicating the VCSEAT2R may be unavailable (MIA).
The vehicle controller does not receive one or more of the expected messages from the VCSEAT2R within the expected time frame.
Vehicle functions that depend on the VCSEAT2R may be unavailable or may not function as expected.
One or more of the messages the vehicle controller receives periodically from the left second row seat controller (VCSEAT2L) is not received, indicating the VCSEAT2L may be unavailable (MIA).
The vehicle controller does not receive one or more of the expected messages from the VCSEAT2L within the expected time frame.
Vehicle functions that depend on the VCSEAT2L may be unavailable or may not function as expected.
The front vehicle controller (VCFRONT) detects a condition affecting the functionality of the left headlight.
The voltage measured across the boost rail, high beam, low beam, DRL, Side Marker, or Turn LEDs is out of range, or the LED drivers in the ECU have reported status flags, or certain values programmed in the headlamp EEPROM are out of range.
Some headlight functions may be unavailable or may not function as expected. Headlight functionality may return after vehicle sleep.
Front trunk (frunk) latch status suggests that the frunk switches are not correctly reporting the latch status. Latch may require replecement.
Controller determines frunk latch switches are not reporting correctly based on recent frunk release and switch interactions.
The frunk latch switches may not report the correct status. The frunk latch switches may report closed when the latch is physically open.
Radiator outlet coolant temperature is higher than the nominal expected value under similar operating conditions.
The difference between radiator outlet coolant temperature and the expected temperature exceeds the threshold.
HVAC cabin cooling (air conditioning) and powertrain performance may be limited.
The current measurement reported by the LV battery (LVBMS_packCurrent) does not match the current sensor on the vehicle controller LV battery feed (IBSCurrent).
The absolute value of current difference between LVBMS_packCurrent and IBSCurrent exceeds nominal expectations
Incorrect battery current data being used, resulting in sub-optimal LV battery management.
The Front Vehicle Controller (VCFRONT) has detected the sleep bypass voltage is low and cannot support vehicle sleep.
The sleep bypass voltage is below 8V.
The load being precharged may not turn on. Vehicle functions relying on the load being precharged may not operate as expected. The vehicle may not sleep and will experience higher idle range loss
EPB calculate brake hw config and epb hw config independently and checks they are the same.
All GTW config valid for EPB. Brake hw type and epb hw type do not resolve to same EPB config
EPB may be misconfigured for vehicle setup. Could result in caliper drag and insufficent clamp force
The front vehicle controller (VCFRONT) detects a power draw higher than expected from the right vehicle controller (VCRIGHT), causing the VCFRONT to power off the VCRIGHT.
There is a sudden high power draw being observed on the VCRIGHT that is outside of the defined operating threshold.
Vehicle may be unable to drive and may start to power down. Vehicle functions that depend on the VCRIGHT (such as right side windows, doors, and/or seat functions) may be unavailable or their performance may be affected.
The front vehicle controller has detected a problem during an eFuse self-test.
Voltage conditions during the self-test sequence are not met.
An eFuse may be unable to turn off or on. Front vehicle controller (VCFRONT) may not function as expected.
The vehicle controller is loadshedding due to a failed LV Health check.
Vehicle LV Health check fails in while vehicle is driving without manual control.
A fault has been detected in the LV system and driverless operation may be unsafe.
