U0145Lost Communication With Body Control Module E
- Generic OBD-II code · Network
- How the car detects it
- U0145 means the network has lost contact with the body controller J2012 labels E. Receiving modules expect its periodic messages; GM's generic logic sets such a code when a supervised message carrying the sender's availability fails to arrive at 9-16 V. Stellantis is the one maker found using U0145 publicly: a 2023 STAR case lists U0145-00 as a LIN bus 3 fault stored in the body control module next to U0140-00, and asks technicians to trace the bus harness and check for loose or pushed-out terminals before replacing the BCM. So on Stellantis vehicles the code points at a LIN branch hanging off the BCM. U0140 to U0144 cover the main and other body modules. MIL stays off; lights, locks or other LIN-driven functions may fail.
- What you may notice
- Individual body functions such as lights or locks inoperative
- Code appears together with U0140 in several modules
- Fault comes and goes when the harness is moved
- Likely causes
- LikelyLoose, spread or pushed-out terminal in the bus harness (Stellantis case)
- PossibleOpen or short on the LIN/CAN line to module E
- PossiblePower or ground of module E missing
- RareBody module E or BCM internally faulty
