Pinpoint Test D : Damper Solenoid Electrical Fault Diagnostic Trouble Codes (DTCS): Notes
Refer to Vehicle Dynamic Suspension for schematic and connector information.
Normal Operation and Fault Conditions
The VDM sends a variable 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 |
|---|---|---|
|
|
This DTC 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. |
|
|
This DTC 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. |
|
|
This DTC 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 or Strut (valve solenoid is serviced as an assembly with the shock or strut)
- 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.
