What does code P0A68 mean?

Q: What does code P0A68 mean?

Drive Motor B Phase U Current High. P0A68 indicates that the inverter or motor control module has detected excessive current flowing through phase U of drive motor B, which is the electric propulsion motor used in hybrid and electric vehicles. The computer compares commanded current against measured current and sets this code when the phase U current exceeds a calibrated threshold for a specified time, signaling a potential short circuit, driver fault, or wiring issue.
