| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
The driver integrated circuit (IC) experiences a condition affecting the operation of the loads controlled by the device.
|
The driver IC reports a condition affecting its operation.
|
Mirror actuations, mirror heating, mirror dimming, or other vehicle operations relying on the driver IC may be inoperative.
|
|
|
The low voltage battery management system (LVBMS) has opened the low voltage (LV) battery's internal protection transistor (MOSFET), disconnecting the LV battery from the rest of the vehicle electrical systems.
|
The LVBMS reports the LV battery's internal protection transistor (MOSFET) is open.
|
The LV battery is unable to support vehicle electrical systems or to recharge via the power conversion system (PCS). The high voltage (HV) system will remain energized to continue supplying electrical power to the vehicle while the LV battery is unavailable. This may result in greater range loss than expected, increased HV system energy consumption when the vehicle is idle, and prevent the vehicle from sleeping.
|
|
|
The low voltage battery management system (LVBMS) is reporting the low voltage (LV) battery's electronic connector position assurance (E-CPA) is not secure, which could result in the LV battery becoming disconnected from the rest of the vehicle electrical systems. This could occur due to the E-CPA locking tab not being fully pushed down, or communication issues between the LVBMS and vehicle controller.
|
The LVBMS is not communicating as expected with the vehicle controller (MIA) or reports the LV battery's E-CPA is not closed.
|
The LV battery may become (or may already be) disconnected from the rest of the vehicle electrical systems, which would make the LV battery unable to support vehicle electrical systems or to recharge via the power conversion system (PCS).
|
|
|
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 the vehicle. However, the LV battery may be recoverable using an external LV Lithium Ion Battery charger tool. A separate alert will indicate whether the battery requires replacement.
|
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 the vehicle. If recovery via an external charger tool is unsuccessful, replacement will be necessary.
|
|
|
There is a greater than 0.5V drop between input power to the front vehicle controller and the 12V Aux Socket Front circuit.
|
0.5V difference between input voltage to the board and the eFuse.
|
Potential hardware issue could cause eFuse to trip or VOR.
|
|
|
Low Voltage (LV) system charge of the LV battery is over current.
|
Battery pack current is greater than the maximum charge current for longer than expected.
|
Drive may not be allowed.
|
|
|
FOHM detects an issue with the input voltage
|
FOHM detects VBAT faults
|
Loss of functionality due to system failure
|
|
|
Unexpected fault in a VNF1048 chip
|
The VNF1048 chip is reporting a fault condition
|
Affected efuse may not be on
|
|
|
Brake Switch Faulted: power rail (5V_MAIN_EXT) required for brake switch reads < 4.5V
|
Brake Switch Faulted: power rail (5V_MAIN_EXT) required for brake switch reads < 4.5V
|
Vehicle controllers will not be made aware of the brake being pressed
|
|
|
Mirror stalled unexpectedly while folding or unfolding
|
If folding motor current exceeds 0.5A or decreases below 0.1A after 500ms from beginning of actuation. Or timeout from current state after 5 seconds.
|
Mirror might be halfway between folded and unfolded
|
|
|
Front exterior handle reported disconnected
|
Handle has just become reconnected or has been disconnected for longer than 1 second
|
If this alert persists the exterior handle may not work
|
|
|
A fault has been detected with the left map pocket light.
|
The light is unplugged, doesn't draw current when on, or its efuse is tripped
|
The left map pocket light may not be working.
|
|
|
Rear exterior handle reported disconnected
|
Handle has just become reconnected or has been disconnected for longer than 1 second
|
If this alert persists the exterior handle may not work
|
|
|
Battery Backed Siren not detected on LIN bus
|
Battery Backed Siren not detected on LIN bus
|
Horn will sound instead of siren during an alarm event
|
|
|
A condition has been detected affecting the left brake light.
|
The light is unplugged, does not draw current when on, or its EFuse is tripped.
|
The left brake light may not function as expected.
|
|
|
The left vehicle controller detects a wiper module communication error, indicating the wiper module may be disconnected.
|
The wiper module is powered for more than 500 ms and wiper communication errors over local interconnect network (LIN) are reported.
|
No wiper functionality.
|
|
|
A condition has been detected affecting the left body-side tail light.
|
The light is unplugged, does not draw current when on, or its EFuse is tripped.
|
The left body-side tail light may not function as expected.
|
|
|
EPB releases no-load is measured using derivative of current. Currently in ghosted alert.
|
No-load current suggested the EPB was not in no-load causing release to continue.
|
EPB may not released far enough causing drag on rotor.
|
|
|
When EPB was applying the current measured went above the max no load current before piston position estimate predicted it would.
|
EPB measure current greater than max no load current before piston position estimate expect it would.
|
EPB may have debris blocking it from clamping correctly.
|
|
|
A condition has been detected affecting the left footwell light.
|
The light is unplugged, does not draw current when on, or its EFuse is tripped.
|
The left footwell light may not function as expected.
