This short guide is to disconnect the electronically controlled suspension (ECS) control module. 91-95 Stealth Twin Turbos and 3000GT VR-4, as well as many of the same year Stealth R/T non-turbo and 3000GT SL models have ECS equipped suspension. The capability to control the struts electronically is only available with the factory Mitsubishi ECS struts (manufactured by KYB).

When you upgrade or change your struts to non-factory struts, either JIC, Tein, KYB GR-2, GAB, or other non-factory strut, you lose the ECS control function. What typically results is the Tour/Sport indicator light in the lower left corner of the main gauge cluster will flash indefinitely. You need to fully disable the ECS system to stop the indicator light from flashing.

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.

Strap up the hatch floor panel with the hook string. Remove the 3 screws holding the passenger side trunk tray and remove the tray. The access panel cover is held in by one Philips screw - remove the panel cover.

Behind this panel you will see a metal computer box. This is the ECS Control Module. It is the only module behind this access panel.

Unplug the harness from the bottom of the module.

That's all you have to do. Replace the panel cover and reinstall the trunk tray. The ECS system is now completely disabled and the Tour/Sport indicator light will no longer flash.
