codes u0001 and u0140
2014 Jeep Cherokee Trailhawk. Got message that a software update was availabl. Hit install now, followed instructions, then check engine light came on when car was restarted and codes u0001 and u0140 were present. Seems like the software update caused this.

I'm sorry to hear this. Those codes are related to the CANBUS and BCM. Please let me know if you will be visiting your dealership for any further diagnosis, and if you need assistance.
