For use with Ford and Lincoln vehicles using a Smart Data Link Connector (aka “Gateway Module”). On vehicles equipped with a Gateway Module, only 2 of the 4+ Communication Networks are available for testing at the standard OBD II DLC. The Gateway Module Breakout Box allows for easy access to all communication networks on a vehicle using either a personal DVOM or a VCMM for enhanced readings. This breakout box connects in series between the Gateway Module and the Gateway Module harness connector and allows ALL vehicle networks to be tested without interrupting normal vehicle operation!
