Signal Name Description Condition Impact
The front vehicle controller (VCFRONT) has detected a condition affecting the right vehicle controller (VCRIGHT) low voltage (LV) power feed circuit (eFuse) during a self-test.
Required voltage conditions are not met during the self-test sequence.
The low voltage (LV) power feed circuit (eFuse) may be unable to regulate (turn on or off) the power supply to VCRIGHT, which could make vehicle functions relying on VCRIGHT limited or unavailable.
An issue with the low voltage (LV) electrical system requires the vehicle to come to a stop immediately. The vehicle should enter graceful power-off (GPO) to exit drive, and a separate alert should indicate that condition.
Lead acid: Low voltage (LV) battery voltage below threshold for 3 seconds (3s); transistor gating LV battery connection is open (no current flow); vehicle load shedding is active; or reverse battery transistor issue detected.
The vehicle will not enter drive. If the vehicle is driving, it will exit drive through graceful power-off (GPO) to come to a stop immediately. A separate alert should be present to indicate the GPO
The vehicle controller detects a difference greater than 3% between readings from the two sensors that measure the low voltage (LV) battery voltage.
The vehicle controller detects a difference greater than 3% between the values reported by the two sensors that measure the LV battery voltage.
There may be some inaccuracy in the vehicle controller's LV bus and LV battery voltage readings. This could lead to accelerated LV battery degradation or an increased likelihood of alerts related to conditions caused by the LV bus voltage being higher or lower than desired.
The front vehicle controller (VCFRONT) detects the front trunk (also known as the frunk) primary latch is experiencing an overcurrent condition, which may prevent the frunk from opening when commanded.
The frunk primary latch draws more current than expected.
The frunk may not open.
The vehicle controller detects that the headlights have not been aimed or require re-aiming.
A replacement front vehicle controller (VCFRONT) has been installed or the Restraints Control Module (RCM) inertial measurement unit (IMU) calibration has been completed.
The headlights may not properly illuminate the area in front of the vehicle or may dazzle oncoming drivers.
The front vehicle controller (VCFRONT) detects the front trunk (also known as the frunk) primary latch is experiencing an undercurrent condition.
The frunk primary latch draws less current than expected.
The frunk primary latch may be disconnected.
The front vehicle controller (VCFRONT) detects more than 8V on the front trunk (also known as the frunk) access post, which may cause the frunk to open if the vehicle is stationary.
The VCFRONT detects a frunk access post voltage of more than 8V.
If the vehicle is stationary, the frunk may open.
The vehicle controller detects that the louver actuator has changed from one type to another.
The front louver does not pass the calibration range check after 5 calibration cycles due to under-travel.
Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.
The low voltage (LV) battery charge cycle was stopped before it reached either its Amp hour or current targets, as the maximum time period for a charging session timeout had been reached.
The vehicle controller detects the maximum LV battery charging session timeout is reached.
Increased energy drain when the vehicle is idle, which may cause lower than expected vehicle state of charge (SOC). LV battery may have lower charge than expected.
The front vehicle controller (VCFRONT) detects the front trunk (also known as the frunk) secondary latch is experiencing an overcurrent condition.
The frunk secondary latch draws more current than expected.
The frunk may not open.
The vehicle controller detects the LV8907 integrated circuit on the thermal fan motor issued a circuit warning, which may prevent the thermal fan from running as expected.
The LV8907 integrated circuit on the thermal fan motor issues a circuit warning that prevents the motor controller from driving the motor.
Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.
The vehicle controller detects the chiller pump motor is unable to reach the target RPM, which may prevent the chiller pump from running as expected.
The chiller pump motor is unable to reach the target RPM.
Powertrain performance may be limited.
The vehicle controller detects the powertrain pump motor is unable to reach the target RPM, which may prevent the powertrain pump from running as expected.
The powertrain pump motor is unable to reach the target RPM.
Powertrain performance may be limited.
The front vehicle controller (VCFRONT) detects the LV8907 integrated circuit on the chiller pump motor issued a circuit warning, which may prevent the chiller pump from running as expected.
The LV8907 integrated circuit on the on the chiller pump motor issues a circuit warning that prevents the motor controller from driving the motor.
Powertrain performance may be limited.

The powertrain pump motor is unable to reach the target RPM.
Powertrain performance may be limited.
The vehicle controller detects the front louver, or active grill shutter (AGS), is unable to calibrate and traveled farther than the expected range without reaching the end stop, indicating the front louver may be damaged.
The front louver does not pass the calibration range check after 5 calibration cycles due to over-travel.
Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.
