Pinpoint Test D : Damper Solenoid Electrical Circuit Faults: Notes
WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Vehicle Dynamic Systems for schematic and connector information.
Normal Operation and Fault Conditions
The GFM2 sends a variable voltage to the damper solenoids based on the current driver selected suspension mode or drive mode. The GFM2 monitors the damper solenoid circuits when the system is in Sport mode (only when the dampers are active) and sets a DTC when a circuit fault is detected. A shorted or open damper solenoid also causes the GFM2 to set a DTC.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| 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 |
These Diagnostic Trouble Codes (DTCs) set in continuous memory or on-demand when the GFM2 detects a short to battery voltage on the damper solenoid high side circuit. |
| 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 |
These Diagnostic Trouble Codes (DTCs) set in continuous memory or on-demand when the GFM2 detects an open on the damper solenoid high side circuit. |
| C1121:11 | Damper Solenoid(s): Circuit Short to Ground | This DTC sets in continuous memory or on-demand when the GFM2 detects a short to ground on any one of the damper solenoid circuits. |
Possible Sources
- Wiring, terminals or connectors
- Shock or Strut (valve solenoid is serviced as an assembly with the shock or strut)
- GFM2
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.
