3SX ECS Module Rebuild Service:

Mitsubishi 3000GT / Dodge Stealth Electronic Control Suspension Unit or ECS

The ECS control module is located in the trunk, behind the interior plastic body panels on the passenger side. Just below the trunk interior light is an access panel. You have to remove the trunk trays to access this panel. Be prepared for this unit to have some damage to it. Real often the electrolytic capacitors on these make quite a mess of the board, sometimes its not a big deal, and can be repaired thoroughly, but others it will be better to just replace it. Controlling the struts electronically is only possible when using the factory Mitsubishi ECS struts. When operating properly the ECS module performs as listed below:

Sport mode -  suspension is set at Hard. 

The damping force can be checked by simply bouncing the mounting points in both modes and checking that the damping force is harder in the Sport state.

Tour mode - activates the following:

Anti-Roll:   If the steering wheel is rotated 90 degrees within 0.3 seconds then the suspension is set at Medium. If this change occurs within 0.2 seconds then it is set at Hard.

Anti-Dive:   When the speed of the car drops quickly during braking the suspension sets itself to Hard.

Anti-Squat:   The suspension will harden at low speeds when accelerating quickly. During hard acceleration at 30km/h the suspension is set at Hard, at 60km/h it is set at Medium, at 90km/h it is set at Soft. At all speeds suspension will change to Medium after a second of acceleration.

High Speed Sensitive:   When accelerating the suspension will change from Soft to Medium at 130km/h and will revert back to soft when the speed drops below 120km/h.

Pitch and Bounce: If the vehicle's body bounces up and down by approx 5cm within a second then the suspension is set at Hard until this motion ceases.

Typical Turn-Around time is 10-14 business days
