Log contains stack usage for each task.
|
Stack usage exceeds 80% for any task.
|
Stack overflow can occur if there is not enough stack space.
|
|
|
Log contains CPU load for each task.
|
CPU load exceeds 80%.
|
High CPU load can indicate ineffecient code.
|
|
|
Production vehicle should not have Debug Jumper in place. Remove jumper from ECU.
|
ECU Debug Jumper is set.
|

|
BCFDM_w090_CrashUnlockError
|
Vehicle did not unlock after crash.
|
These are the repercussions of the alert being set

|
This alert exists purely to provide diagnostic information for FW development. Because this alert is triggered only as part of the mirror tilt test routine, it is not expected to occur as part of customer use.
|
When the mirror position feedback does not indicate a significant change after about 3 seconds of automatic adjustment.
|
Auto-recall for mirror tilt position may exhibit problems

|
the ESP has shutdown before stable acceleration values could be captured
|
Engineering debug alert only
|
|
|
The door stopped unexpectedly while opening or closing.
|
The door controller detected a stopping condition while opening or closing. Alert payload data should provide more information on specific condition(s) involved.

|
BCFDM_w080_CurrentDropOut
|
A significant drop in current is seen while actuator is being driven
|
Actuator will temporarily not respond to being driven
|
|
|
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
|
|
|
The door zero position is cleared.
|
The door zero position was cleared due to latch closing while door angle is above threshold value, the angle reaching threshold negative value, or the door controller resetting while latch is not closed. Alert payload data should provide more information on specific condition(s) involved.
|
The door power operation is disabled.
