Remedy
When a Open Cycle starts, the OTC will send a
command to the Honda System to unlock the
doors. It then sends a second command to the
Honda System to open the Right Side Sliding
Door. The OTC Computer then waits two
seconds and checks the Door Closed Limit
Switch. If it finds it still indicates the door is
closed, it assumes that a person (or and
obstacle) stopped the door opening sequence. It
then ends the open cycle and goes back into Idle
Mode. After ten to fifteen seconds it goes back
into Sleep Mode. Once the OTC knows the door
has begun to open, the Door Detector counts the
pulses from the door motor to indicate how far
open the door is. Once enough pulses have been
received the Door Detector thinks the door is
open all the way and send the signal to deploy
the ramp. See Door Detector Section for more
information.
Engage ramp motor. Refer to the "Manual
Operation" section of this manual.
