U02A3: Understanding The Fuel System Pressure Control Circuit
The U02A3 fault 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 U02A3 code sets when a periodic message from the Particulate Matter Sensor Module has not been received, indicating a lost communication with the module. The supervision time-out period for messages is 250 ms, and each message contains the identification number of the transmitter module.
The DTC sets when the receiver module does not receive periodic messages from the Particulate Matter Sensor Module, which has prerecorded information about what messages are needed to be exchanged on the serial data circuits.
