The U016B code is related to the high-speed General Motor Local Area Network (GMLAN) serial data circuits. Modules connected to the GMLAN monitor for serial data communications during normal vehicle operation. The U016B code sets when a periodic message from the Electric AC Compressor Control Module has not been received.

This code indicates a lost communication with the Electric AC Compressor Control Module.

The supervision time-out period for messages is 250 ms.

The DTC sets when the receiver module does not receive periodic messages from the transmitter module.
