Fault Family System: Powertrain (P-Codes) 4 SAE Codes

Control Pilot Indicator Control

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.

These 4 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 4 times.
