| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
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 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 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.
|
|
|
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.
|
|
|
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.
|
|
|
One or more of the messages the vehicle controller receives periodically from the heat pump system compressor (CMPD) electronic control unit (ECU) is not received, indicating the CMPD ECU may be unavailable (MIA).
|
One or more of the expected messages from the CMPD ECU is not received.
|
The HVAC system may be unavailable or may not function as expected.
|
|
|
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 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 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 seat armrest motor is uncalibrated.
|
The seat armrest motor is uncalibrated.
|
Seat position recall may be unavailable.
|
|
|
The seat armrest motor current is below the expected threshold, causing the motor to be unresponsive.
|
The seat armrest motor current is below the expected threshold.
|
The seat may be unable to move.
|
|
|
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.
|
|
|
One or more of the messages the vehicle controller receives periodically from the drive interface (DI) electronic control unit (ECU) is not received while the vehicle is in Drive, indicating the DI ECU may be unavailable (MIA).
|
One or more of the expected messages from the DI ECU is not received while the vehicle is in Drive.
|
Vehicle speed and power may be limited.
|
|
|
The seat armrest motor is not providing encoder feedback.
|
The seat armrest motor is not stalling, the current draw is not zero, and the encoder values are not increasing.
|
Seat memory recall may be unavailable.
|
|
|
The seat armrest motor unexpectedly stalls.
|
The seat armrest motor current draw exceeds the stall limit.
|
The seat armrest motor may recalibrate.
|
|
|
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.
|
|
|
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.
|
|
|

|
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
|
|
|
One or more of the messages the vehicle controller receives periodically from the front vehicle controller (VCFRONT) is not received, indicating the VCFRONT may be unavailable (MIA).
|
The vehicle controller does not receive one or more of the expected messages from the VCFRONT within the expected time frame.
|
Vehicle functions that depend on the VCFRONT may be unavailable or may not function as expected.
|
|
|
