Pinpoint Test E : Suspension Height Sensor Electrical Faults: 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 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 |
One or more of these 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 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 U200E:11 |
Control Module Output Power A: Circuit Short to Ground Control Module Output Power B: Circuit Short to Ground |
One or more of these DTCs sets in continuous memory when the VDM detects a short to ground on one or more of the height sensor power circuits. |
| U200D:12 U200E:12 |
Control Module Output Power A: Circuit Short to Battery Control Module Output Power B: Circuit Short to Battery |
One or more of these DTCs sets in continuous memory when the VDM detects a short to battery on one or more of the height sensor power circuits. |
