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.
