I am fairly new to JLR vehicles I own a 2019 f pace and just picked up my 2019 rrs and i would like to program/ troubleshoot using topix and pathfinder but i am unsure of what tools i need. I have a obdII scan tool but it is basic not able to give deep codes.
Do i need a handheld interface as well as a cable like the mongoose or just one or the other. and if not both what would i need the interface for.
Sorry for the seemingly newbie question but when i do all the google searches piecing it all together is unclear so i figured i would ask those with experience with these vehicles.
I have troubleshooted and worked on all my vehicles for 25 years and never trusted bringing it in to a shop but this brand is new to me and would love some guidance. Thanks.
