Signal Name Description Condition Impact
CAN messages from the Lane Keep Assist System (LKAS) ECU have an invalid steering angle demand range, indicating an error in data integrity has been detected.
CAN message frames from the LKAS ECU have an out of range steering angle demand value
Active Driver Assist System (ADAS) control is disabled, and Steering assist may be affected, since the Lane Keep Assist System (LKAS) to Steering Torque Overlay (STO) interface is interrupted
CAN messages from a wheel speed sensor ECU have an invalid speed signal range, indicating an error in data integrity has been detected.
CAN message frames from a wheel speed sensor ECU have an out of range wheel speed signal value
Steering assist may be affected, since the wheel speed to Steering Torque Overlay (STO) interface is interrupted
CAN messages from a wheel speed sensor ECU have an invalid data length, indicating an error in data integrity has been detected.
For 1 or more seconds, CAN message frames from a wheel speed sensor ECU have an invalid data length
Steering assist may be affected, since the wheel speed to Steering Torque Overlay (STO) interface is interrupted
A slow software trip has been detected due to Low Voltage (LV) readings exceeding the expected limit during operation.
LV voltage exceeds the expected threshold for the given time interval.
High rated low voltage causes thermal issues for loads rated at lower voltages.
