What the code means

Lost Communication With Body Control Module A. Generic meaning per SAE J2012 (the same for all makes).

How to read U0141: the letter U means network communication between modules; the second digit 0 marks a generic SAE code shared by all makes; the last three characters 141 identify the specific fault.

Lost communication codes (U0xxx) mean one module cannot hear another on the data bus. The cause can be the module itself, its power or ground, or a damaged wiring harness. After a crash this is a typical trace: the impact tears wiring in the rail, fender or rocker and modules drop off the network.

Check wiring harnesses in the impact zone: rail, fender, rocker, pillar.
Check the battery and grounds: low voltage triggers false lost communication codes.
Budget a network scan: a missing module may be intact while its wiring is damaged.

Then at times I would be locked out for extended periods of time. After the oil pump in the transmission went out I had it checked for codes and it showed U0141 as being stored. After the transmission was fixed they were in the process of delivering it back and it started acting up on their way with it.

When you're on a fixed income bringing your vehicle in for repairs is not always feasable. I took the jeep to autozone free diagnostic and got a code U0141. After reading the similar stories we're going into the dealership for repairs.
