Hello and welcome to JustAnswer!

P1686 sets when the powertrain control module isn't receiving a bus message from the SKIM module. This would cause a start/die issue, if you aren't experiencing starting issues at this time then you can disregard this one.

P0700 sets in the powertrain control module when there is one or more fault code in the transmission control module. Do you know what codes are setting in the TCM?
