| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
A sudden transition out of Accessory Plus state was requested, where entertainment and media may have been actively used while in Park (including Arcade Mode or Theater Mode). Drive will be unavailable for 10 seconds while the vehicle transitions to ensure that adequate electrical power is available to enter Drive and avoid accidental entry into Drive as the brake pedal may have been recently used for gaming.
|
The low voltage (LV) battery may have become unsupported and not have sufficient energy, or the high voltage (HV) battery state of charge (SOC) is too low, to immediately support drive on sudden request to exit an accessory state (for entertainment and media while parked) and drive the vehicle.
|
The vehicle will not enter Drive state for 10 seconds.
|
|
|
HVAC intake actuator faulted.
|
The intake actuator detected a fault (check context data for type of fault)
|
The heater and the A/C and heater may be disabled
|
|
|
The vehicle is unable to drive because it has been placed in Showroom Mode, a mode intended for display rather than driving. This should not occur with a production vehicle once it has been delivered. If this occurs due to an error, service is required to exit Showroom Mode.
|
An attempt is made to enter drive while the vehicle is in Showroom Mode.
|
The vehicle is unable to drive.
|
|
|
Recovery limp mode activated based on user acknowledgment of possible shutdown and limited drive torque / functionality.
|
User acknowledges limited drive torque and possible shutdown, after steering system has been detected as partially compromised and vehicle has been brought to a stop, and shifts out of Park.
|
Vehicle speed limited to less than 5 mph. Brakes eventually applied automatically to bring vehicle to a stop.
|
|
|
Window thermal protection mode engaged
|

|
The local ECU does not receive one or more of the expected messages from the EGGRIGHT1 within the expected time frame.
|
Vehicle functions that depend on the EGGRIGHT1 may be unavailable or may not function as expected.
|
|
|
Window thermal protection mode engaged
|
Repeated window cycling in a short period of time
|
No user-initiated down/closing movement permitted in THERMAL_ALERT mode, no user-initiated movement permitted in THERMAL_CRITICAL mode
|
|
|
One or more of the expected CAN messages from the Etherloop Generalized Gateway Left (Core 1) were not received, indicating the EGGLEFTVC ECU may be unavailable (MIA).
|
The local ECU does not receive one or more of the expected messages from the EGGLEFTVC within the expected time frame.
|
Vehicle functions that depend on the EGGLEFTVC may be unavailable or may not function as expected.
|
|
|
A condition has been detected during an attempt to close the center console door, and the center console lid might not be closed correctly.
|
The left vehicle controller (VCLEFT) detects that the center console door switch has switched more than 6 times in 5 seconds.
|
Center console lid might not be closed correctly.
|
|
|
The Electronic Parking Brake or Electronic Parking Brake Monitor took longer than expected to save caliper state in non-volatile memory.
|
Caliper state saved to Electronic Parking Brake and Electronic Parking Brake Monitor mismatched for more than 500ms
|
Non-volatile memory error due to Electronic Parking Brake and Electronic Parking Brake Monitor mismatch
|
|
|
The Electronic Parking Brake and Electronic Parking Brake Monitor took longer than expected to save caliper state in non-volatile memory.
|
Caliper state saved to Electronic Parking Brake and Electronic Parking Brake Monitor mismatched
|
Non-volatile memory error due to Electronic Parking Brake and Electronic Parking Brake Monitor mismatch
|
|
|
Window current is too low while being driven
|
Measured window current is below a certain threshold for some minimum time

|
|
|
Steering column in / out motor is not calibrated. The steering column will hit hard stops and not recall.
|
Steering column is uncalibrated. The calibration routine has not run, ran unsuccessfully, or the steering column reports that it reached an implausible in / out position.
|
Steering column hits hard stops during in / out adjustments and will not recall to the proper position.
|
|
|
12V auxiliary power socket EFuse is tripped due to an overcurrent event, making the power socket unavailable.
|
12V auxiliary power socket overcurrent event.
|
12V auxilary power socket will be unavailable until left vehicle controller (VCLEFT) has reset or vehicle completes a sleep/wake cycle.
|
|
|
The caliper may be disconnected.
