Reasons to keep the controller awake have been the same for greater than one hour
|
The bus could not sleep causing significant range loss for the battery pack
|
|
|
Encoder counts not changing
|
The track motor senses a failure in detecting movement
|
The track motor will be disabled
|
|
|
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 - 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
|
|
|
check occupancy sensor and harness, seat belt sensor and harness, damaged ECU
|

|
|
|
3930 Fault - Low Load Current. Senses less than 500mV
|
Track motor senses low current
|
Fault flag thrown, track motor will continue to work
|
|
|
Seat temperature sensor may be disconnected, shorted, or faulted
|
The temperature sensor senses a fault and is either shorted or disconnected
|
The 2nd row seat heater may be disabled
|
|
|

|
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
|
|
|
