P0CC6Charge Port Door A Open Request Switch Wake-Up Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Needs a drive cycle to confirm a fix
- How the car detects it
- On plug-in vehicles the button that asks for the charge flap to open must also be able to rouse a sleeping control module, so it drives a separate wake-up line besides its normal signal. P0CC6 records that these two signals disagree. GM documents the code for the 2011 Chevrolet Volt, where the hybrid control module 2 (VICM) checks two cases: wake-up active although the switch reads released, and switch pressed with no wake-up seen. Both are filtered over 50 ms samples and stored as Type B after two trips with the warning lamp. The test is skipped while P0CC7, P0CC9 or P0CCA is active, so P0CC6 points to the wake-up wire or the switch contact itself. The driver mostly notices that pressing the button sometimes does not open the flap.
