|
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
|
|
|
Seat temperature sensor may be disconnected, shorted, or faulted
|
The temperature sensor senses a fault and is either shorted or disconnected
|

|
|
|
A large voltage drop is detected in the input power to the vehicle controller, indicating the resistance on the input power feed to the vehicle controller is higher than expected.
|
Estimated resistance on the input power feed to the vehicle controller is higher than expected.
|
The vehicle controller may be unavailable due to lack of adequate input power, limiting vehicle functionality or making the vehicle inoperable, with at least one other alert specific to that condition present.
