|
Door latch release cam cannot find home position
|
Door latch actuator does not reset the release cam to the home position in the time allotted
|
Door may not be able to close
|
No
|
|
|
Window encoder ticks not seen while the front window motor is being driven: This suggests something is disconnected, shorted, or the controller voltage supply for the encoders is < 9V
|
Window motor is being driven and no encoder feedback is seen within 500 ms
|

|
The interior door release button and window switch(es) will be unavailable
|
No
|
|
|
More than half of the ECUs on a either the VEH or PARTY bus are missing more than half their messages while the bus should be active
|
If 50% or more of the ECUs the local ECUs listens to are MIA, and the local ECU receives from more than 3 ECUs on this bus. An ECU is MIA if more than 50% of its messages are MIA and that ECU is considered CAN active (see specific ECU's MIA alert for CAN active conditions).

|
May short drop and reverse at all positions, no anti-pinch detection
|
No
|
|
|
Lack of current and encoder ticks from the presenter indicates it is no longer connected to the controlller
|
Current draw falls below the undercurrent threshold and no encoder counts are seen when a high enough voltage is applied to the presenter motor
