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.

Likely causes

Open, chafed or shorted wake-up wire between switch and control module
Worn or contaminated contact in the open request switch
Corroded or loose pins at the switch or module connector
Faulty wake-up input inside the control module

Symptoms

  • Charge flap opens only after several presses or not at all
  • Warning lamp after two trips (GM Volt)
  • Possible extra drain on the 12 V battery if the module is kept awake
