Vehicle Dynamics Control Module (VDM)

WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The VDM is the ECU for the vehicle dynamic suspension. The VDM monitors all sensor inputs and all HS-CAN2 messages relating to the vehicle dynamic suspension and then directly controls the valve solenoids.

When a new VDM is installed, the module must be programmed with the vehicle configuration information. Refer to: Module Configuration - System Operation and Component Description .

When one of the following components is installed new, disassembled, disconnected or removed the VDM requires calibration.

Suspension height sensor
Front upper control arm
Front lower control arm

The calibration procedure is required for the system to learn the zero-position of the vehicle which means the vehicle must be on a level surface, must not be moving and cannot contain any passengers or cargo. The calibration procedure is carried out using a diagnostic scan tool. The calibration routine should not be performed with the vehicle raised off the ground or immediately after lowering the vehicle as the suspension will not be in a neutral position. The suspension must be neutralized before performing the calibration routine by driving the vehicle for a short distance such as around a parking lot.
