2. CHECK JAM PROTECTION FUNCTION
CAUTION:
Do not put your hands between the vehicle body and automatic running board to check functions. Also, prevent any part of your body from being caught during inspection.
(a) Check the jam protection function while the automatic running board is being stowed.
(1) Open the door and fully deploy the automatic running board.
(2) Close the door and stow the automatic running board.
(3) While the automatic running board is being stowed, insert a tire or equivalent between the automatic running board and vehicle body, in order to interrupt the stowing operation.
(4) Check that the jam protection function is immediately activated and that the automatic running board reverses operation and moves to the deployed position.
HINT:
When there has been a jam 3 times in succession, the side auto step ECU judges that there is deemed to be an obstacle (a foreign obstacle) and stops the automatic running board in the position where the jam protection function has operated.
(b) Check the jam protection function while the automatic running board is deploying.
(1) Close the door and fully stow the automatic running board.
