Family: Battery Charger Charge Sequence Signal
Code P2E8C: Battery Charger B Charge Sequence Signal 1 Circuit High
Diagnostic & Technical Explanation
Code P2E8C (Battery Charger B Charge Sequence Signal 1 Circuit High) covers the low-voltage handshake signals (numbered 1 and 2) the onboard charger and vehicle control module exchange to step through a charge session's startup and shutdown sequence, distinct from the control pilot and proximity circuits shared with the EVSE. The ECM flags the signal reading high or low outside its expected window at a given sequence stage. Causes are a corroded connector between the charger and control module, chafed low-voltage sequencing wiring, or an internal charger fault that never asserts the expected signal.

and diagnostic findings support it. Its cost and labor estimates (where known), the step-by-step procedure and the
remaining 2 procedure(s) are in the licensed dataset. Ordering context.
