| 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.
