How do I fix DTC U0140 and U0155
Seeing U0140 and U0155 from the bcm, instrument panel, radio and chime. Been chasing this issue for a very long time. Tested grounds, power and low speed data…all seem fine.

you wouldn't get U0140 from the BCM because it doesn't need to communicate with itself. Anyway since this is unrelated to EBCM I'm moving your question to its own thread. Please post your vehicle details. Thanks.
