PINPOINT TEST E : DTCs B1162, B1163, B1164 AND B1170: Notes
WARNING: This page is about a different car, the 2016 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Power Liftgate/Retractable Running Boards , for schematic and connector information.
Normal Operation
The Power Running Board(PRB) module provides a regulated 10-volt power supply to the Hall-effect sensor (internal to the PRB motor) through circuit CPR47 (GY/BN). The Hall-effect ground is provided by the PRB module through circuit RPR47 (BU/GN). The PRB module monitors the PRB Hall-effect signal through circuit VPR43 (GY/BU) (LH) or VPR46 (GY) (RH). If the PRB module does not receive any signal from the Hall-effect sensor during operation, the PRB will stop.
| DTC Description | Fault Trigger Conditions |
|---|---|
| B1162 - Power Running Board Hall-Effect Sensor Power Circuit Short to Battery | The PRB module sets this DTC if it detects the Hall-Effect sensor power circuit is shorted to battery voltage. |
| B1163 - Left Power Running Board Hall-Effect Sensor Failure | The PRB module sets this DTC if it does not see any feedback from the Hall-Effect sensor during the stowing/deploying of the LH running board. |
| B1164 - Power Running Board Hall-Effect Sensor Power Circuit Short to Ground | The PRB module sets this DTC if it detects the Hall-Effect sensor power circuit is shorted to ground. |
| B1170 - Right Power Running Board Deploy and/or Stow Circuit Short to Battery | The PRB module sets this DTC if it does not see any feedback from the Hall-Effect sensor during the stowing/deploying of the RH running board. |
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- PRB module
- LH or RH PRB motor assembly
