|---|---|---|---|
|
The Body Controller Front Driver Door (BCFDM) or Body Controller Front Passenger Door (BCFPM) detects latch is not fully closed after ramping.
|
The BCFDM or BCFPM detects latch is not fully closed after ramping. The BCFDM detects latch is not fully closed after ramping.
|
Door will not close properly. If vehicle is locked, alarm may sound.
|
|
|
BCFDM_w073_UnexpectLatchOpen
|
Latch reported open or ajar but PFD is actually closed
|

|
|
BCFDM_w071_LatchFailedToRelease
|
Latch was opening and now we are not opening but the latch is not open or ajar
|
-
|
|
|
BCFDM_w070_LatchFailedToCinch
|
Latch was closing and now we are not closing but the latch is not closed
|

|
|
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.
|
|
|
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.
|
|
|
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
|
|
|
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
|
|
|
Need to save PFD actuator-specific calibration values into NVRAM via Toolbox.
|
Door brake data is using default values
|
The door brake hold force may be wrong
|
|
|
Check the alert log for the specific failure code.
|
The latch reports an error code over LIN
|
The latch may fail to operate properly
|
|
|
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
|
|
|
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
|
|
|
BCFDM_w057_ReflectorLamp
|
The desired state of the reflector lamp could not be set, the current state is not the expected one or the light did time out
|
These are the repercussions of the alert being set
|
|
|
BCFDM_w056_MirrorHeatError
|
Mirror heat enable failed
|
Mirror may not be heated when it should be
|
|
|
BCFDM_w055_PFDSetState
|
Error setting state in state machine
|
Setting a bad state could require power cycle, undefined behavior
|
|
|
BCFDM_w054_PFDIOProcessData
|
Fail to process IO data
|
IO data may be invalid
|
|
|
BCFDM_w053_PFDIOInit
|
TBD
|
TBD
|
|
|
BCFDM_w052_PFDBadState
|
Bad/unknown state in state machine
|
Power cycle needed to initialize state
|
|
|
BCFDM_w065_ratchetingDetected
|
If front door is releasing and braking continously
|
Worse user experience as the door
|
|
|
BCFDM_w051_DoorBrake

TBD
