Important Notes
The security gateway module needs to be connected for the dealership service tool to work properly, and should be removed prior to any dealership service. The installation of the STE Chrysler pass through connector will modify the vehicle’s electronic communication system, which may affect the warranty of your vehicle.
Installation Overview
The STE Chrysler pass through connector is required for all 2018+ Chrysler FCA vehicles due to the addition of a security gateway module. This module prevents most OBD devices from operating on the vehicle, but the STE pass through connector allows for normal OBD device operation.
Installation Steps
For Durango and Jeep Grand Cherokee models, the security gateway module is located on the left side of the passenger footwell below the glove box. Remove the three black plastic push pins, pull the silencer panel down, and disconnect the two connectors from the security gateway module.
Insert the connectors into the STE pass through connector, ensuring that both connectors are fully seated into the pass through by pressing on the backs of the connectors.
