Principles of Operation
The Power Running Boards (PRBs) are controlled by the Power Running Board (PRB) module. The PRB motors receive motor power and ground from the PRB module. The PRB module receives door ajar switch status and vehicle speed information from the Controller Area Network (CAN).
When in AUTO mode, the PRBs will deploy when a door on the same side of the vehicle is opened. When both doors on the same side are closed, the PRBs will retract.
When in OUT mode, both PRBs will stay deployed until OUT mode is deselected, reset to AUTO mode or vehicle speed is greater than 8 km/h (5 mph). Mode will automatically switch back to AUTO once above 8 km/h (5 mph).
When an obstacle is detected, the PRB will reverse direction. If a second obstacle is detected, the PRB will reverse direction again. If a third obstacle is detected, the PRB will stop against the third obstacle until the following conditions are met:
· Change in door ajar status
· Change in the message center status (AUTO, OUT, OFF)
· Vehicle speed greater than 8 km/h (5 mph)
Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.
