P0E6B Hybrid/EV Battery Precharge Contactor Control Circuit Low
The HV battery precharge contactor reports a control circuit low condition. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
