DTC P0CC6

The hybrid powertrain control module 2 monitors the voltage values of the charge port wake-up signal circuit and the charge port request signal circuit. When the charge port door release switch is pressed, the two switch contacts close and provides B+ voltage to the two signal circuits. This provides B+ to the Wake-up Circuit input of the hybrid powertrain control module 2 and lowers the voltage on the fuel door request signal circuit input to the hybrid powertrain control module 2, The hybrid powertrain control module 2 detects the voltage on the signal circuits and provides a 12 V pulse to the charge port relay, the relay briefly becomes energised which then allows B+ voltage to the charge port door latch which activates and releases the charge port door.

Hybrid Powertrain Control Module 2 is awake

The hybrid powertrain control module 2 detects that the Charge Port Door Open Request Switch Wake-Up Circuit value does not match the expected corresponding value for the Charge Port Door Open Request resistor ladder switch input.

The charge port door will not open if the hybrid powertrain control module 2 is asleep

DTC P0CC6 is a type B DTC

Vehicle is Service Mode, command the charge port door OPEN by pressing the S113 charge port door open request switch. The M80 charge port door unlatch actuator should unlatch and the charge port door should open

1. Vehicle OFF, disconnect the harness connector at the S113 charge port door open request switch.
2. Verify that a test lamp illuminates between the B+ circuit terminal 1 and ground.

⇒	If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

3. Connect the harness connector at the S113 charge port door open request switch.
4. Disconnect the X2 harness connector at the K114B hybrid powertrain control module 2.
5. Connect a test lamp between the signal circuit terminal 29 and ground.
6. Observe the function of the test lamp while pressing and releasing the S113 charge port door open request switch. The test lamp should turn ON each time the switch is pressed.

⇒	If the test lamp is always ON, test the signal circuit for a short to voltage. If the circuit tests normal, test or replace the S113 charge port door open request switch.

⇒	If the test lamp is always OFF, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, test or replace the S113 charge port door open request switch.

7. If all circuits test normal, replace the K114B hybrid powertrain control module 2.

1. Vehicle OFF, disconnect the harness connector at the S113 charge port door open request switch.
2. Test for infinite resistance between the signal terminal 2 and the B+ terminal 1 with the switch in the open position.

⇒	If not the specified value, replace the S113 charge port door open request switch.

3. Test for less than 2 Ω between the signal terminal 2 and the B+ terminal 1 with the switch in the closed position.

⇒	If greater than the specified range, replace the S113 charge port door open request switch.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
