|
|
|
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 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.

|
Seat position recall may be unavailable.
|
|
|
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.
|
|
|
One or more of the messages the vehicle controller receives periodically from the right Electronic Park Brake (EPBR) electronic control unit (ECU) is not received, indicating the EPBR ECU may be unavailable (MIA).
|
The vehicle controller does not receive one or more of the expected messages from the EPBR ECU within the expected time frame.
|
The parking brake may be unavailable or may not function as expected.
|
|
|
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
|
|
|
One or more of the messages the vehicle controller receives periodically from the left Electronic Park Brake (EPBL) electronic control unit (ECU) is not received, indicating the EPBL ECU may be unavailable (MIA).
|
The vehicle controller does not receive one or more of the expected messages from the EPBL ECU within the expected time frame.
|
The parking brake may be unavailable or may not function as expected.
|
|
|

|
Seat memory recall will be unavailable
|
|
|
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
|
|
|
One or more expected Controller Area Network (CAN) messages from the Electronic Stability Program (ESP) electronic control unit (ECU) was not received. Stability and traction control functions may be unavailable, or their performance may be affected.
|
An expected CAN message from the Electronic Stability Program (ESP) electronic control unit (ECU) has not been received within the expected timeout, or the message drop rate is too high while the ESP is CAN active. The ESP is considered CAN active when VCFRONT_privateGoToSleep is 0 AND VCFRONT_espLVState is LV_ON.
|
Stability and traction control functions may be unavailable, or their performance may be affected.
|
|
|
The seat track motor is not calibrated, which may cause position recall to be unavailable.
|
