P0D06Control Pilot Charging Ventilation Switch Stuck On
- Generic OBD-II code · Powertrain
- How the car detects it
- Stuck On means the ventilation switch remains closed when it should be open, so the pilot is held near 3 V and the station reads a permanent demand for charging with ventilation. Stations that cannot provide ventilation do not supply power in that state, which in practice stops charging altogether. Likely causes are a welded or sticking switch, a short across the 270 Ω branch, or a module output that no longer releases. No manufacturer documents this code publicly; GM's Chevrolet Volt checks the same switch through P0D01 by the pilot level it causes in a self-test, and Mercedes-Benz documents the matching failure of charging switch A as P0CFE00 (switch not opening, cured by software). The counterpart is P0D05, circuit faults are P0D00 to P0D03. The car is detected at the station but does not charge.
