Family: Control Pilot Indicator Control
Code P0D2B: Control Pilot Indicator Control Circuit/Open
Diagnostic & Technical Explanation
Code P0D2B sets when the driver circuit for the control pilot indicator lamp — the dashboard or charge-port light reflecting the pilot signal's handshake state — reads an open, a short to ground, or a short to voltage instead of the commanded state. The most common physical causes are a burned-out bulb or failed LED, a corroded or unseated connector at the indicator, and chafed wiring between the control module and the lamp. Because this indicator only reflects pilot-handshake status, a fault here affects what the driver sees rather than the charge session itself, which is governed by the separate control pilot signal circuit.

This is the first procedure in the authored
consideration order, not a measured cause likelihood. Execute it only when its prerequisites
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.
