Note
Some vehicles may have a 1st Generation DCDC Converter, yet are built with a 2nd Generation logic harness. For these vehicles, an additional 2nd Generation to 1st Generation logic jumper harness (1030144-00-A) has been pre-installed, and a second connector with an HVIL jumper is taped to the logic harness under the cabin fuse box 1. For the retrofit of these vehicles, remove the 2nd Generation to 1st Generation jumper harness altogether, remove the HVIL jumper from the second connector, and route the second connector to the distribution box. Additionally, a 5A fuse may have been pre-installed into location 26 of the cabin fuse box 1. Refer to Toolbox article 166400 for additional information.
