WebISO15765-4, dual-wire CAN, is mandatory on ALL North American vehicles sold from Model Year 2008 and forward for Powertrain communications. It was phased in by OEMs starting in MY2004, so refer the specific wiring schematic and the DLC connector. If there are pins in DLC cavities 6 & 14 after MY2003 it is wired up for HSCAN. WebIf in doubt, measure the resistance between CAN High and CAN Low without the system powered up. The resistance should ideally be less than 120 Ohms and closer to 60 Ohms if a resistor is fitted at each end of the bus. CAN bus systems which are already active (i.e. a vehicle CAN bus system) will already have the correct amount of termination. dance clubs in atlantic city
