If your diagnostic interface is built to listen on CAN1, it will not show engine parameters or fault codes unless you use a cross over adapter that maps CAN3 engine traffic into CAN1. This Diesel Laptops converter provides that bridge and works with a wide range of industry diagnostic hardware.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles require this CAN3-to-CAN1 adapter?\u003c\/h3\u003e\n\u003cp\u003eSome manufacturers moved engine data onto CAN3 beginning around the 2016 model year.
