| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
One or more of the expected CAN messages from APP were not received.
|
A message the local ECU expects to receive from the APP ECU hasn't been received within the expected timeout or the drop rate is too high while the APP is CAN active. The ECU is considered CAN active when VCFRONT_chGoToSleep is 0.
|
Autopilot functionality may be missing.
|
|
|
Brake temperature is above 200C and slope is greater than 5%.
|
One Electronic Parking Brake faulted and the max of the rear brake calipers is hotter than 200 C and slope is greater than 5%
|
Car may not be secured by Electronic Parking Brake on current road grade, may be free rolling
|
|
|
The vehicle controller detects output voltage from the air compressor for the air suspension system when none is expected. The vehicle controller's fused high current eFuse circuit will be used to deenergize the air compressor.
|
Air compressor output voltage is detected when the air compressor has been requested off.
|
The air compressor for the air suspension system is unavailable, making air suspension functionality limited or unavailable.
|
|
|
An issue is indicated from the non-volatile memory manager.
|
Non-volatile memory misconfiguration or underlying flash/filesystem error.
|
Non-volatile memory records may be incorrect or missing.
|
|
|
There is an unexpected condition affecting a VNF1048 chip.
|
The VNF1048 chip reports a condition affecting its operation.
|
Affected eFuse may not be on.
|
|
|
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.
|
|
|
The Emergency Notification Signal (ENS) harness may be disconnected or the Restraints Control Module (RCM) may be missing (MIA).
|
Emergency Notification Signal (ENS) period is not within 10% of 0.001 or 0.1 seconds, and duty cycle is not between 60% and 40%.
|
Loss of redundancy on high voltage disconnection signal.
|
|
|
Vehicle speed is limited based on ultrasonic distance measurements. Currently in ghosted alert.
|
Autopilot command speed to DI is too high for reported Object on Course.
|
Summon will be abruptly aborted.
|
|
|
Warns if the processor has experienced a reset due to watchdog reset.
|
A watchdog (external or internal) was not serviced in time.
|
Controller is MIA for some time.
|
|
|
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
|
|
|
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.
|
|
|
The seat heater has had unusually high current draw.
|
Seat heater current has reached above a permitted threshold.
|
Seat heater will stop running. Potential damage to harness and seat.
|
|
|
The high side driver (HSD) for the rear right seat heater has detected an error condition, which may lead to the seat heater not performing as designed.
|
The high side driver (HSD) for the rear right seat heater detects an error condition (overcurrent, short to ground, or thermal shutdown).
|
The rear right seat heater may not perform as designed.
|
|
|
The motor cannot reach the target RPM. Powertrain performance may be limited.
|
The motor RPM is incapable of reaching the target RPM for some time.
|
The pump will not run. Powertrain performance may be limited. A reset will occur to attempt to clear the fault.
|
|
|
The motor has a circuit warning. Powertrain performance may be limited.
|
The LV8907 integrated circuit has detected a warning that requires a stop
|
The pump will not run. Powertrain performance may be limited. The fault will clear when the condition is no longer present.
|
|
|
The motor has a circuit warning. Powertrain performance may be limited.
|
The LV8907 integrated circuit has detected a warning that requires a stop
|
The pump will not run. Powertrain performance may be limited. The fault will clear when the condition is no longer present.
|
|
|
The tonneau and tailgate switches are being inhibited due to a switch voltage being out of bounds.
|
At least one of the three tonneau/tailgate switches are out of bounds
|
The tonneau and tailgate will not respond to switch actuation
|
|
|
The motor has detected an electrical fault (short, disconnect, or internal). Powertrain performance may be limited.
|
The LV8907 integrated circuit has detected a fault that requires a stop.
|
The pump will not run. Powertrain performance may be limited. The circuit will be reset to attempt to clear the fault.
|
|
|
The motor has a circuit warning. Powertrain performance may be limited.
|
The LV8907 integrated circuit has detected a warning that should be reported.
|
The pump may not run. Powertrain performance may be limited.
|
|
|
The motor has a circuit warning. Powertrain performance may be limited.
|
A non-zero brushless motor RPM below the RPM target is not increasing for some time.
|
The pump will not run. Powertrain performance may be limited. A reset will occur to attempt to clear the fault.
