Pinpoint Test F : C1008:93, C1009:93, C1B14:11, C1B14:12: Notes
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Retractable Running Boards for schematic and connector information.
Normal operation and Fault Conditions
The RBM monitors the movement, position and current draw of each PRB with a hall-effect switch that is integral to each PRB motor. The RBM supplies a shared 10 volt controlled voltage and a shared ground circuit to the PRB motor hall-effect sensors, and receives separate sensor signals from the RH and LH hall-effect sensors. Voltage varies on the LEFT or RIGHT RB hall-effect signal circuit as the motor moves the PRB. An open or shorted circuit will set these DTC.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C1008:93 | Left Power Running Board Position/Motion Sensor: No Operation | This DTC sets if the system voltage is between 9.5 - 16 volts, the LH PRB motion is commanded and the left RB hall effect signal circuit at the RBM does not change. |
| C1009:93 | Right Power Running Board Position/Motion Sensor: No Operation | This DTC sets if the system voltage is between 9.5 - 16 volts, the RH PRB motion is commanded and the right RB hall effect signal circuit at the RBM does not change. |
| C1B14:11 | Sensor Supply Voltage A: Circuit Short To Ground | This DTC sets if the system voltage is between 9.5 - 16 volts, any PRB motion is commanded and the hall effect power circuit at the RBM is less than 7.5 volts. |
| C1B14:12 | Sensor Supply Voltage A: Circuit Short To Battery | This DTC sets if the system voltage is between 9.5 - 16 volts, any PRB motion is commanded and the hall effect power circuit at the RBM is greater than 10 volts. |
