P0D1E Hybrid/EV Battery Pack Coolant Control Valve B Control Circuit High
The HV battery pack coolant control valve B reports a control circuit high 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.
