Pinpoint Test E : Height Sensor Electrical Faults: Notes
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
Height Sensor Electrical Faults
Refer to Wiring Diagram Vehicle Dynamic Suspension for schematic and connector information.
Normal Operation and Fault Conditions
REFER to: Vehicle Dynamic Suspension - System Operation and Component Description . The VDM continually monitors the height sensor circuits and sets a DTC when a circuit fault is detected. A shorted height sensor also causes the VDM to set a DTC.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C1A03:11 C1A04:11 C1A05:11 C1A06:11 |
Left Front Height Sensor: Circuit Short to Ground Right Front Height Sensor: Circuit Short to Ground Left Rear Height Sensor: Circuit Short to Ground Right Rear Height Sensor: Circuit Short to Ground |
One or more of these Diagnostic Trouble Codes (DTCs) sets in continuous memory when the VDM detects a short to ground or an open on one or more of the height sensor signal circuits. |
| C1A03:12 C1A04:12 C1A05:12 C1A06:12 |
Left Front Height Sensor: Circuit Short to Battery Right Front Height Sensor: Circuit Short to Battery Left Rear Height Sensor: Circuit Short to Battery Right Rear Height Sensor: Circuit Short to Battery |
One or more of these Diagnostic Trouble Codes (DTCs) sets in continuous memory when the VDM detects a short to battery on one or more of the height sensor signal circuits. |
| U200D:11 | Control Module Output Power A: Circuit Short to Ground | One or both of these Diagnostic Trouble Codes (DTCs) sets in continuous memory when the VDM detects a short to ground one or more of the height sensor power circuits. |
| U200E:11 | Control Module Output Power B: Circuit Short to Ground | |
| U200D:12 | Control Module Output Power A: Circuit Short to Battery | One or both of these Diagnostic Trouble Codes (DTCs) sets in continuous memory when the VDM detects a short to battery on one or more of the height sensor power circuits. |
| U200E:12 | Control Module Output Power B: Circuit Short to Battery |

- Wiring, terminals or connectors
- Height sensor
- VDM
Visual Inspection and Diagnostic Pre-checks
- Make sure the height sensor harness is routed correctly and is undamaged.
- Make sure the height sensor electrical connector is free from any corrosion or other contaminants.
