B1170 Description


The Power Running Board (PRB) module provides a regulated 10-volt power supply to the Hall-effect sensor (internal to the PRB motor) through the circuit. The Hall-effect ground is provided by the PRB module through the circuit. The PRB module monitors the PRB Hall-effect signal through the circuit. If the PRB module does not receive any signal from the Hall-effect sensor during operation, the PRB will stop. The PRB module sets this Diagnostic Trouble Code (DTC) if it does not see any feedback from the Hall-Effect sensor during the stowing/deploying of the RH running board.
