Vehicle Dynamics Control Module (VDM)
WARNING: This page is about a different car, the 2023 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The VDM monitors all sensor inputs and all HS-CAN messages that relate to the vehicle dynamic suspension and then directly controls the valve solenoids. The VDM sends an individual electrical current to each valve solenoid to control the amount of damping required.
The VDM requires calibration when any of the following components is installed new, disassembled, disconnected or removed.
- VDM
- Suspension height sensor
- Front upper control arm
- Front coil over shock assembly
- Rear control arm
- Rear shock
The calibration procedure is carried out using the diagnostic scan tool and required for the system to learn the zero-position of the vehicle.
Before performing the calibration procedure:
- Be sure the vehicle is on a level surface.
- The vehicle must not be moving.
- No occupants in the vehicle.
- Make sure the suspension is in a neutral position if it was recently lowered. To neutralize the suspension, drive the vehicle a short distance, such as around a parking lot.
