U160F on Chevrolet
On GM trucks and SUVs, U160F means lost communication with brake system control module 1 on CAN bus 1
Severity: Inspect soon
The code means the brake control module dropped off the network, and owners report many lost-communication codes with it, stability control faults and, in one case, loss of drive power, so braking and drive systems can be affected.
It gets more serious if:
- Stop: Stop if brake or stability warnings appear with a loss of power, steering assist or other modules: pull over safely and arrange a tow.
