This alert probably indicates that a firmware bug was encountered. Resetting the front door body controller will temporarily resolve the issue.
|
Front door latch reports OPEN when body controller reports that the latch is CLOSED, or vise versa.
|
Vehicle will not properly detect that the door is open or closing. May also trigger several other power front door alerts.
|
No
|
|
|
The body controller will automatically re-issue an undrop command if a failure to undrop is detected.
|
~1000 milliseconds pass after latch closes without window undrop movement (if window is at the short drop position).
|
Window undrop will be delayed by about 1000 ms as the door closes.
|
No
|
|
|
The body controller will automatically re-issue a short-drop command if a failure to drop is detected.
|
70-80 milliseconds pass after latch opening without window drop movement (if window is fully closed)
|
Window may briefly catch on body frame as door opens
|
No
|
|
|
Not to be confused with a weak cinch. This alert does not imply problems with seal load or door alignment.
|
Latch cinches, reports closed briefly, and then ajar.
|
Front door may not be able to cinch closed
|
No
|
|
|
BCFPM_w065_ratchetingDetected
|
If front door is releasing and braking continously
|
Worse user experience as the door
|
No
|
|
|
Check alertLog for more information. If resultingState is CLOSED_BRAKE, the latch's OPEN switch may be disconnected. If previousState is OPENED_BRAKE, the latch's switches and release motor may be all disconnected.
|
PFD transitions from LATCH_OPENING to CLOSED_BRAKE or OPENED_BRAKE
|
PFD cannot open automatically
|
No
|
|
|
The linkage may have become detached at the ball joint. This alert is only present in factory mode.
|
A possible issue with the PFD acutator linkage was detected
|
The door shuts off all powered operation until closed and latched
|
No
|
|
|
Check the alert log for the specific failure code.
|
The latch reports an error code over LIN
|
The latch may fail to operate properly
|
No
|
|
|
Check OTP region of DFLASH
|
Error reading from OTP.
|
Genealogy information may not be read.

For engineering diagnoses only
|
Front door just transitioned from unzeroed->zeroed

|
Response timeout of a LIN node
|
These are the repercussions of the alert being set
|
No
|
|
|
Can sometimes be remedied by pulling/replacing fuse 233 under the MCU
|
Latch is not communicating over LIN
|
The latch may not work if it is of the cinching type
|
No
|
|
|
latch feedback switches are most likely harnessed incorrectly
|
OPEN switch is active and AJAR switch is not active
|
Door latch status is incorrectly reported and PFD operation becomes erratic
|
No
|
|
|
Check if DOOR_READ_EN is enabled (pulled low) at startup; check that the doorID pins are being set low in correspondence with the desired side; run UDS routine 204 on the bootloader to read and store the side config
|
The ECU did not read the door ID pins properly on reset or power was connected before harness with door ID pins
|
The ECU may not respond to the desired signals and ECU should be reset
|
No
|
|
|
reseting the controller should fix the issue
|
Driver side config stored in NVRAM does not match the config sent by GTW
|
controller may have behaviors that correspond with the wrong side of the car
|
No
|
