|
The radar circuit (RADC) has detected a condition with the cyclic redundancy check (CRC). RADC may not operate as expected.
|
RADC detects a condition with the CRC.
|
The RADC might not operate as expected and may compromise radar-based functionalities on the vehicle.
|
|
|
The radar circuit (RADC) has detected that the memory built in self-test (BIST) has been disabled. RADC may not operate as expected.
|
RADC detects a condition with the BIST.
|
The RADC might not operate as expected and may compromise radar-based functionalities on the vehicle.

Steering control from this node is disabled
|
|
|
Handwheel rotation delta comparison with other sources failed
|
One or more angle sources is not within the velocity dependent allowed error bounds
|
Loss of steering feedback
|
|
|
The local Electronic Control Unit (ECU) has not received one or more expected Controller Area Network (CAN) messages from the internal steering bus.
|
The local Electronic Control Unit (ECU) did not receive a message it was expecting from the ECUs on the specified internal steering bus within the expected timeout.
|
Power Steering functionality may be degraded.
|
|
|
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 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.
|
|
|
Handwheel center is calibrated to center of mechanism and may be offset from visual center.
|
Handwheel calibration is captured during the FIND-CENTER routine.
|
Vehicle does not drive straight while holding the handwheel at visual center.
|
|
|
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.

|
|
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.
|
|
|
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.
