|---|---|---|---|---|
|
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.
|
No
|
|
|
Motor is not calibrated
|
On startup, Electronic Power Steering (EPS) detects motor calibration is incomplete
|
Motor torque may not be generated
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No

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.
|
No
|
|
|
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
|
No
|
|
|
The Primary Electric Power Steering (PEPS) detected the Rear Steering Actuator (RSA) is not functioning as expected.
