Pinpoint Test E : Height Sensor Electrical Fault Diagnostic Trouble Codes (DTCS): Notes
WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Vehicle Dynamic Suspension for schematic and connector information.
Normal Operation and Fault Conditions
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 |
This DTC sets in continuous memory when the VDM detects a short to ground or an open on one or more of the height sensor 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 |
This DTC sets in continuous memory when the VDM detects a short to battery on one or more of the height sensor circuits. |
