This standard is valid for OBDII connectors except for Nissan Leaf (where primary and alternate CANs have been historically switched). At some point it would be good to get away from that proprietary Nissan Leaf cable, but we’d need to do it in a transparent way (presumably by listening on both buses for traffic, before transmitting anything, and then deciding which is which dynamically).<div class=""><div class=""><br class=""></div><blockquote style="margin: 0 0 0 40px; border: none; padding: 0px;" class=""><div class=""><blockquote class="" style="font-family: "Times New Roman", Times, serif; font-size: 16px; margin: 0px 0px 0px 40px; border: none; padding: 0px;"><div dir="auto" class="" style="word-wrap: break-word; line-break: after-white-space;"><div class="">For DB9 cables:</div><div class=""><br class=""></div></div></blockquote><blockquote class="" style="font-family: "Times New Roman", Times, serif; font-size: 16px; margin: 0px 0px 0px 40px; border: none; padding: 0px;"><div dir="auto" class="" style="word-wrap: break-word; line-break: after-white-space;"><div class=""><font face="Andale Mono" class=""><span class="" style="font-size: 18px;">Pinout “C"</span><br class=""><br class=""><span class="" style="font-size: 18px;">J1962-M DB9-F Signal</span><br class=""><span class="" style="font-size: 18px;">4 3 Chassis/Power GND</span><br class=""><span class="" style="font-size: 18px;">6 7 CAN-H (primary CAN)</span><br class=""><span class="" style="font-size: 18px;">14 2 CAN-L (primary CAN)</span><br class=""><span class="" style="font-size: 18px;">13 5 CAN-H (alternate CAN)</span><br class=""><span class="" style="font-size: 18px;">12 4 CAN-L (alternate CAN)</span><br class=""><span class="" style="font-size: 18px;">16 9 +12V Vehicle Power</span><br class=""><br class=""><span class="" style="font-size: 18px;">J1962 end should be MALE plug with angle cable.
