What are you using to do the scan? What symptoms does your car show? Have you had any work done on the car? More info please. This DTC indicates a communication glitch between the HV Battery ECU and the rest of the Canbus has been logged. The only posts on PriusChat of someone getting this code indicate that it occurred when they plugged in the scanner while the car was in Ready mode. It did not happen when they plugged in first, and then made the car ready. Gen II Prius Individual Battery Module Replacement | Page 2 | PriusChat
