Hello Everyone,

i have a 2015 IS350 and during the last cold snap/snow storm my Blind Spot Monitoring stopped working. I found the following codes stored in the system:
U1002 Lost Communication with Gateway Module
U0233 Lost communication with Blind Spot Monitor Master Module
U0126 Lost Communication with Steering Angle Sensor Module
U0129 Lost Communication with Brake System Control Module
U0142 Lost Communication with Body Control Module "B"

Given that these are all loss of communication could this all be related to maybe water/snow/mag chloride getting into something it shouldn't have been in? When things warmed up a little bit the system started working again.

Thanks for any input!
