The seat armrest motor current draw exceeds the stall limit.
|
The seat armrest motor may recalibrate.
|
No
|
|
|
The seat armrest motor travels beyond the expected range.
|
The seat position goes beyond the acceptable range, causing the seat armrest motor to overtravel.
|
The seat may be in an unstable position.
|
No
|
|
|
The seat armrest motor encoder unexpectedly stalls with a high current draw.
|
The seat armrest motor current draw exceeds 70% of the stall limit, and the encoder does not move for 100ms.
|
The seat motor encoder may increment incorrectly if an obstruction is encountered.
|
No
|
|
|
The seat motor has traveled beyond the expected range.
|
Seat position goes outside the acceptable range.
|
Seat may be in an unstable position or a mechanism may not be functioning as expected.
|
No
|
|
|
The seat track motor current is below the expected threshold, causing the motor to be unresponsive.
|
The seat track motor current is below the expected threshold.
|
Seat may be unable to move.
|
No
|
|
|
The seat track motor has unexpectedly stalled.
|
Current draw exceeds stall limit.
|
Motor will recalibrate if the stall is in an expected region, do nothing otherwise.
|
No
|
|
|
The seat backrest motor current is below the expected threshold, causing the motor to be unresponsive.
|
The seat backrest motor current is below the expected threshold.
|
Seat may be unable to move.
|
No
|
|
|
The seat backrest motor is not providing encoder feedback to controller
|
The current draw is not 0 and the seat backrest motor is not stalling, but the encoder value does not increase
|
Seat memory recall will be unavailable
|
No
|
|
|
The seat heater temperature sensor has an electrical fault. This sensor is used for fault management of the airbag system
|
The sensor is disconnected or short-circuited to ground
|
Occupancy sensing will be impacted
|
No
|
|
|
The backrest motor is uncalibrated
|
Motor calibrated is 0
|
Position recall unavailable
|
No
|
|
|
The seat heater has an unusually high current draw.
|
The seat heater current draw is above the acceptable threshold.
|
The seat heater may be unavailable. If the seat heater is continued to be used, the seat and/or seat harness may be damaged.
|
No
|
|
|
Second row seat has detected an obstacle during actuation.
|
Second row seat speed decreased unexpectedly, did not move at all, or exceeded the motor current threshold.
|
Second row seat may not be able to complete the desired actuation.
|
No
|
|
|
The seat track motor is not providing encoder feedback to controller
|
The current draw is not 0 and the seat track motor is not stalling, but the encoder value does not increase
|
Seat memory recall will be unavailable
|
No
|
|
|
The second row seat is physically blocked by the front row seat, preventing seat movement.
|
The second row seat is requested to move but may collide with the front row seat, and the front row seat is unable to automatically move out of the way.
|
The front row seat may need to be manually adjusted to allow the requested second row seat movement to complete.
|
No
|
|
|
The high side driver (HSD) for the second row seat heater has detected a short-circuit, which may lead to the seat heater not performing as designed.
|
The high side driver (HSD) for the second row seat heater detects a short-circuit.
|
The front seat heater may not perform as designed.
|
No
|
|
|
Seat track motor is close to exceeding normal operating times
|
The operating time exceeds 90 seconds within 5 minutes
|
The seat track motor will be disabled if operation is continued and exceeds 120 seconds within 5 minutes
|
No
|
|
|
One or more of the messages the vehicle controller receives periodically from the Steering Column Control Module (SCCM) is not received, indicating the SCCM may be unavailable (MIA).
|
One or more of the expected messages from the SCCM is not received.
|
Vehicle may be unable to shift between drive modes.
|
No
|
|
|
One or more of the messages the vehicle controller receives periodically from the right vehicle controller (VCRIGHT) is not received over the interprocessor controller area network (IPC), indicating the VCRIGHT may be unavailable (MIA).
|
One or more of the expected messages from the VCRIGHT is not received over the IPC.
|
Vehicle functions that depend on the VCRIGHT may be unavailable or may not function as expected.
|
No
|
|
|
The seat track motor is not calibrated, which may cause position recall to be unavailable.
|
The seat track motor is detected as uncalibrated (calibrated state of the seat track motor is 0).
|
Position recall may be unavailable, meaning the preset user preferences for seat positions may also be unavailable.
|
No
|
|
|
Seat track motor overuse is detected with number of operating events within 5 minutes
|
The seat track motor exceeds the allowed number of operating events per time period.
