Hello fellow members,
Sienna XLE Premium 2019/3rd generation
I was wondering if anyone has encountered the same issue and if anyone knows how to fix it? Starting from around 2 weeks ago my Sienna started to play this message: "Communication module activation failed. Please make sure in an area with good cellular coverage and try again." Usually it happens as soon as I start the engine but sometimes repeats while I am driving. Any idea what this is related to and is it possible to fix it without getting dealership/garage involved?
Your help would be much appreciated
