Hello friends,
I'm the owner of 2014 Jeep Wrangler JK (diesel 2.8 CRD) - 100% stock.
Will try to describe situation I'm dealing with now, maybe you know the way I should go.
I've been off for a two weeks to another country & as I've returned back, started my Wrangler - got lots of indicators on dash: ABS, Traction, Check engine, Stop/Start Not Ready, Service Stop/Start system, speedo also doesn't work...
I took my diagnostics, the codes are:

U0121-00 Lost communication with ABS control module - Status Active
U0122-00 Lost communication with Vechicle Dynamics control module - Status Active
U0129-00 Lost communication with Brake System control module 1 - Status Active / Pending
P0501-00 Vehicle speed sensor 1 Performance - Status Active
U0001-00 CAN C Bus - Stored

Firstly, I thought my battery went down, replaced it - still having this troubles...
Trying to erase them, but they appear as soon as I'll erase them.
Service stop/start system - also sounds strange, what could be wrong with it?

Regards,
Roman
