| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
Check seat heater pad for damage or disconnected seat heat pad wire.
|
When commanded on, the seat heater temperature has not risen 2 degC or more in the 45 seconds it has been powered on
|
The seat heater may not be operational or may have poor heating performance
|
|
|
Check seat temperature sensor for fault.
|
The heat pad is present, the temperature sensor is not disconnected and the value is less than -38 degC with a valid ambient reading of more than 10 degC, all for more than 3 seconds
|
The 2nd row seat heater may be disabled
|
|
|
Encoder counts not changing as expected.
|
The pitch motor senses a failure in detecting movement
|
The pitch motor will be disabled
|
|
|
Current below expected, free spinning. Seat could have pitched out from its screw.
|
Pitch motor senses low current of less than absolute value of +/- 1 amp for greater than 1 second
|
Pitch motor could be disconnected and seat would not be able to track
|
|
|
Stall detection. Check for obstacle detected, high current readings, or running into pitch ends.
|
The pitch motor reads an unreasonably high or stall current of greater than absolute value of +/-15 amps for greater than 50 ms
|
The pitch motor will be disabled
|
|
|
check occupancy sensor and harness, seat belt sensor and harness, damaged ECU.
|
3rd row detects occupancy sensor is in the faulted or disconnected voltage range
|
Occupant safety is impacted
|
|
|
check occupancy sensor and harness, seat belt sensor and harness, damaged ECU.
|
3rd row detects buckle switch is in the faulted or disconnected voltage range

|
|
|
check occupancy sensor and harness, seat belt sensor and harness, damaged ECU.
|
2nd row detects occupancy sensor is in the faulted or disconnected voltage range
|
Occupant safety is impacted
|
|
|
check occupancy sensor and harness, seat belt sensor and harness, damaged ECU.
|
2nd row detects buckle switch is in the faulted or disconnected voltage range
|

|
|
|
Encoder counts not changing.
|
The track motor senses a failure in detecting movement
|
The track motor will be disabled
|
|
|
Check for obstacle detected, high current readings, or running into track ends.
|
The track motor reads an unreasonably high or stall current of FILL_THIS_OUT amps
|
FILL_THIS_OUT
|
|
|
3930 Fault - Under voltage, Overtemperature, Incorrect Logic Levels.
|
Vreg < 8V, Overtemperature > 170 deg C on the A3930,Logic levels below lockout voltage level of 4V
|
If overtemperature, A3930 will continue to drive. If undervoltage or logic fault, motor control will be disabled.
|
|
|
3930 Fault - Low Load Current. Senses less than 500mV.
|
Track motor senses low current
|
Fault flag thrown, track motor will continue to work
|
|
|
3930 Fault - short to GND, short to Supply, shorted motor winding.
|
Track motor detects a short
|
Comfort track and easy entry will be disabled
|
|
|
Check if 5V_SW is enabled at startup; check that the seatID pins are being set low in correspondance with the desired side; run UDS routine 204 on the bootloader to read and store the seat config.
|
The ECU did not read the seat ID pins properly on reset
|
The ECU may not respond to the desired signals
|
|
