What does code P2CC1 mean?

Q: What does code P2CC1 mean?

Generator Voltage Sense Circuit B. P2CC1 indicates that the engine control module (ECM) has detected an abnormal voltage signal on the generator voltage sense circuit B, which is used to monitor the charging system's output. The ECM compares this signal to expected values and sets the code when the voltage is out of range or inconsistent with other charging system inputs.
