| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
Warns if the processor has experienced a reset due to watchdog reset.
|
A watchdog (external or internal) was not serviced in time.
|
Controller is MIA for some time.
|
|
|
The seat armrest motor is uncalibrated.
|
The seat armrest motor is uncalibrated.
|
Seat position recall may be unavailable.
|
|
|
The Vehicle Seat Controller (VCSEAT1) detects the seat track motor exceeds the expected operating times, causing the motor to be disabled.
|
The seat track motor operating time exceeds 120 seconds within the past 5 minutes.
|
The seat track motor is disabled.
|
|
|
The backrest motor encoder has unexpectedly stalled
|
Current draw exceeds 70% of stall limit and encoder not moving for 100ms
|
Encoder may increment incorrectly if obstruction encountered
|
|
|
The track motor encoder has unexpectedly stalled
|
Current draw exceeds 70% of stall limit and encoder not moving for 100ms
|
Encoder may increment incorrectly if obstruction encountered
|
|
|
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.
|
|
|
The calibration for the second row seat was unsuccessful or did not run.
|
Second row seat movement is requested, but the seat calibration was unsuccessful or did not run.
|
Automatic fold and unfold movements for the second row seat are unavailable. Only manual seat adjustments are available.
|
|
|
The backrest motor is uncalibrated
|
Motor calibrated is 0
|
Position recall unavailable
|
|
|
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
|
|
|
Second row seat calibration failed or did not run.
|
Second row seat calibration failed or did not run.
|
Second row seat automatic fold and unfold movements are not allowed. Only manual adjustments are allowed.
|
|
|
The 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 have failed
|
|
|
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
|
|
|
The backrest motor has unexpectedly stalled, which may cause the motor to recalibrate.
|
The current draw of the backrest motor has exceeded the stall limit.
|
If the stall occurs in an expected region, the backrest motor may recalibrate.
|
|
|
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.
|
|
|
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.
|
|
|
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.
|
|
|
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.
|
|
|
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.
|
|
|
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.
|
|
|
The second row seat occupancy sensor has an internal short or open, preventing the sensor from determining the occupancy of the seat.
|
The second row occupancy sensor has an internal short or open.
|
The second row seat occupancy sensor cannot determine the occupancy of the seat.
