B1167 Possible Causes
Faulty Power Running Board Motor Assembly,Power Running Board Motor Assembly harness is open or shorted,Power Running Board Motor Assembly circuit poor electrical connection,Faulty Power Running Board (PRB) Module
During Power Running Board (PRB) deployment, the PRB module supplies power to the PRB motor and ground through the circuit. The PRB module stows the PRB by supplying power to the PRB motor and ground through the circuit. The 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 a short to battery voltage is detected in the LH running board motor circuit(s).
