Pinpoint Test A : The Power Adjustable Steering Column Is Inoperative In One Or More Directions Using The Steering Column Control Switch: Notes
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
Diagnostic Overview
Refer to Adjustable Steering Column for schematic and connector information.
Normal Operation and Fault Conditions
When the steering column control switch (mounted directly to the SCCM) is activated, the SCCM supplies voltage and ground to the applicable steering column tilt or telescoping motor to move the steering column to the desired position.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1375:18 | Steering Column Tilt Motor: Circuit Current Below Threshold | This DTC sets when the SCCM senses current flow to the adjustable steering column tilt motor is below a preset limit while the steering column control switch is activated. This may be caused by an open or high resistance in the adjustable steering column tilt motor circuits. |
| B1375:19 | Steering Column Tilt Motor: Circuit Current Above Threshold | This DTC sets when the SCCM senses current flow to the adjustable steering column tilt motor is above a preset limit while the steering column control switch is activated. This may be caused by a short to ground in the adjustable steering column tilt motor circuits. |
| B1375:71 | Steering Column Tilt Motor: Actuator Stuck | This DTC sets when the SCCM senses current flow to the adjustable steering column tilt motor is within a specific range but above a preset limit during on-demand self test. |
| B137E:18 | Steering Column Telescope Motor: Current Below Threshold | This DTC sets when the SCCM senses current flow to the adjustable steering column telescopic motor is below a preset limit while the steering column control switch is activated. This may be caused by an open or high resistance in the adjustable steering column telescopic motor circuits. |
| B137E:19 | Steering Column Telescope Motor: Current Above Threshold | This DTC sets when the SCCM senses current flow to the adjustable steering column telescopic motor is above a preset limit while the steering column control switch is activated. This may be caused by a short to ground in the adjustable steering column telescopic motor circuits. |
| B137E:71 | Steering Column Telescope Motor: Actuator Stuck | This DTC sets when the SCCM senses current flow to the adjustable steering column telescopic motor is within a specific range but above a preset limit during on-demand self test. |
