Once the OTC sends the signal to operate the OEM Door,
a timer starts. If enough time passes before the proper
limit switch is activated at the end of the cycle, the OTC will
return this error.
If OEM B-Pillar Switch is not working, try the OEM
Overhead Door Switch and make sure the OEM Overhead
Door On/Off Switch is on.
If Door Limits function correctly and door cycles open and close
okay, the issue is with the door taking too long to open or close.
Check alignment or motor.
If an Output is an issue, the Door Control Error (Error 11)
will likely display.

Reset - Esc - Kneel Up/Kneel Down
Testing with Power Overide is preferreed since it will incidicate
if Limit Switch is being properly activated by Actuator's Guide.
When Kneel Actuator reaches its run limit, it will begin to ratchet
making a terrible sound. This is simply the motor's clutch
mechanism, is not damaging but should try and be minimized.
If OTC Debug Output Test does not activate the motor
being tested, try the overides located on the OTC Relay
Board. This will inidicate a communication problem
between the One Touch Controller and One Touch Relay
Board.
Also a low battery, bad motor or cold weather causing the
motor to run very slowly can return this error.
