Pinpoint Test D : Damper Solenoid 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 sends a PWM voltage to the damper solenoids based on sensor input and HS-CAN messages. The VDM continually monitors the damper solenoid circuits and sets a DTC when a circuit fault is detected. A shorted or open damper solenoid also causes the VDM to set a DTC.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C110C:11 C110D:11 C110E:11 C110F:11 |
Left Front Damper Solenoid: Circuit Short to Ground Right Front Damper Solenoid: Circuit Short to Ground Left Rear Damper Solenoid: Circuit Short to Ground Right Rear Damper Solenoid: 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 both of the damper solenoid circuits for longer than 3 seconds. |
| C110C:12 C110D:12 C110E:12 C110F:12 |
Left Front Damper Solenoid: Circuit Short to Battery Right Front Damper Solenoid: Circuit Short to Battery Left Rear Damper Solenoid: Circuit Short to Battery Right Rear Damper Solenoid: Circuit Short to Battery |
One or more of these DTCs sets in continuous memory when the VDM detects a short to battery voltage on one or both of the damper solenoid circuits for longer than 3 seconds. |
| C110C:13 C110D:13 C110E:13 C110F:13 |
Left Front Damper Solenoid: Circuit Open Right Front Damper Solenoid: Circuit Open Left Rear Damper Solenoid: Circuit Open Right Rear Damper Solenoid: Circuit Open |
One or more of these DTCs sets in continuous memory when the VDM detects an open circuit on one or both of the damper solenoid circuits for longer than 3 seconds. |
Possible Sources
- Wiring, terminals or connectors
- Shock (valve solenoid is serviced as an assembly with the shock)
- VDM
Visual Inspection and Diagnostic Pre-checks
- Make sure the valve solenoid harness is routed correctly and is undamaged.
- Make sure the valve solenoid electrical connector is free from any corrosion or other contaminants.
