| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
Steering system performance degraded due to condition detected affecting functionality.
|
Any condition detected affecting steering system functionality.
|
Steering system performance is degraded, and vehicle speed is limited.
|
|
|
Steering system unable to follow commands due to one or more conditions affecting functionality.
|
Any condition affecting steering system functionality that will prevent operation / make the steering system unable to follow commands.
|
Vehicle is unable to drive or continue driving.
|
|
|
Steering power is reduced as the vehicle has entered Drive power state while being powered by the jump post.
|
The vehicle enters Drive state while being powered by the jump post.
|
Steering performance may be reduced until the vehicle exits then re-enters Drive state (vehicle power cycle occurs) with the jump post power source disconnected.
|
|
|
Steering power is reduced as Transport Mode has been enabled.
|
Transport Mode is enabled.
|
Steering performance may be reduced until Transport Mode is disabled.
|
|
|
Power steering startup sequence is unsuccessful.
|
Controller calibration check is unsuccessful, corresponding controller monitor is not responding, or state timeout occurs.
|
The motor is disqualified and system health is degraded.
|
|
|
Power steering startup sequence is unsuccessful.
|
Controller calibration check is unsuccessful, corresponding controller monitor is not responding, or state timeout occurs.
|
The motor is disqualified and system health is degraded.
|
|
|
The motor factory calibration record is missing or invalid.
|
Motor factory calibration record missing or invalid
|
Motor factory calibration may be missing, preventing operation
|
|
|
The Primary Electric Power Steering (PEPS) detected the Rear Steering Actuator (RSA) is not functioning as expected.
|
PEPS detected the RSA is not functioning as expected. See alert log signal data for more information.
|
Rear steering may be unavailable during the current drive cycle.
|
|
|
Rear axle steering is disabled at low vehicle speeds, based on user request via front touchscreen (UI). Rear wheels will align at 0 degrees.
|
Low vehicle speed and user request via front touchscreen (UI)
|
Rear axle steering will still turn in parallel at higher speeds for vehicle stability, but turning radius will be reduced at lower speeds
|
|
|
Rear axle steering has been re-enabled at all speeds.
|
User request via front touchscreen (UI)
|
Rear axle steering will operate nominally at all vehicle speeds.
|
|
|
A phase current offset of a steering controller is greater than the expected variance. Steering may not operate as expected.
|
A phase current offset greater than the expected variance is detected.
|
Steering may not operate as expected. Controller may be damaged.
|
|
|
The primary motor position sensor has been deemed invalid.
|
The motor position sensor signals have failed a safety check.
|
The motor is disqualified and rack control health is degraded.
|
|
|
Steering motor current continuity is irrational. The sum of the three phase currents is not equal to 0.
|
Observed current into motor does not match current exiting.
|
The motor is disqualified and system health is degraded.
|
|
|
The secondary motor position sensor has been deemed invalid.
|
The motor position sensor experiences an issue affecting configuration and/or communication, or magnetic flags are set.
|
The motor is disqualified and handwheel feedback health is degraded.
|
|
|
Motor is not calibrated
|
On startup, Electronic Power Steering (EPS) detects motor calibration is incomplete
|
Motor torque may not be generated
|
|
|
The power steering motor phase disconnect signaled an error.
|
The phase disconnect detects an error condition (e.g. voltage out of range, communication issue, FET short).
|
The motor is disqualified and rack control health is degraded.
|
|
|
One or more steering motor position sensor readings are invalid.
|
Any motor position sensor is deemed invalid, or readings from valid sensors disagree by more than allowed threshold.
|
Invalid sensor readings could affect systems reliant on position data.
|
|
|
Steering current calibration is unsuccessful.
|
Motor phase or bus current calibration offset is out of the nominal range.
|
The motor is disqualified and system health is degraded.
|
|
|
The gate driver reported an electrical condition preventing operation.
|
The gate driver is reporting an electrical condition affecting its functionality.
|
The motor is disqualified and system health is degraded.
|
|
|
One or more of the messages the vehicle controller receives periodically from the rear vehicle controller (VCREAR) is not received, indicating the VCREAR may be unavailable (MIA).
|
The vehicle controller does not receive one or more of the expected messages from the VCREAR within the expected time frame.
|
Vehicle functions that depend on the VCREAR may be unavailable or may not function as expected.
