DTC Descriptor
DTC P0CC6 00
- Charge Port Door Open Request Switch Wake-Up Circuit
Diagnostic Fault Information
Circuit/System Description
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 energized which then allows B+ voltage to the charge port door latch which activates and releases the charge port door.
Conditions for Running the DTC
Hybrid Powertrain Control Module 2 is awake
Conditions for Setting the DTC
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.
Action Taken When the DTC Sets
The charge port door will not open if the hybrid powertrain control module 2 is asleep
Conditions for Clearing the DTC
DTC P0CC6 is a type B DTC

Circuit/System Verification
1. Vehicle in Service Mode.
2. Verify the operation of the charge port door when commanding the charge port door actuator to UNLATCH by pressing the charge port door open request switch.
• If the charge port door actuator does not UNLATCH
Refer to Circuit/System Testing
• If the charge port door actuator does UNLATCH
3. All OK.
Circuit/System Testing
1. Vehicle OFF, disconnect the harness connector at the S113 charge port door open request switch. Vehicle in Service Mode.
2. Verify a test lamp illuminates between the B+ circuit terminal 1 and ground.
• If the test lamp does not illuminate and the circuit fuse is good
1. Vehicle OFF.
2. Test for less than 2 ohms in the B+ circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, verify the fuse is not open and there is voltage at the fuse.
• If the test lamp does not illuminate and the circuit fuse is open
1. Vehicle OFF.
2. Test for infinite resistance between the B+ circuit and ground.
• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance
3. Disconnect the X2 harness connector at the K114B hybrid powertrain control module 2.
4. Test for infinite resistance between the signal circuit terminal 2 and ground.
• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance, replace the K114B hybrid powertrain control module 2.
• If the test lamp illuminates
3. Vehicle OFF, connect the harness connector at the S113 charge port door open request switch. Disconnect the X2 harness connector at the K114B hybrid powertrain control module 2.
4. Connect a test lamp between the signal circuit terminal 29 and ground.
5. Verify the test lamp turns ON and OFF by pressing the S113 charge port door open request switch.
• If the test lamp is always OFF
1. Vehicle OFF, disconnect the harness connector at the S113 charge port door open request switch.
2. Test for infinite resistance between the signal circuit and ground.
• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance
3. Test for less than 2 ohms in the control circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, test or replace the S113 charge port door open request switch.
• If the test lamp is always ON
1. Vehicle OFF, disconnect the harness connector at the S113 charge port door open request switch, Vehicle in Service Mode.
2. Test for less than 1 V between the control circuit and ground.
• If 1 V or greater, repair the short to voltage on the circuit.
• If less than 1 V, test or replace the S113 charge port door open request switch.
• If the test lamp turns ON and OFF
6. Replace the K114B hybrid powertrain control module 2.
Component Testing
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 less than infinite resistance
Replace the S113 charge port door open request switch.
• If infinite resistance
3. Test for less than 3 ohms between the signal terminal 2 and the B+ terminal 1 with the switch in the closed position.
• If 3 ohms or greater
Replace the S113 charge port door open request switch.
• If less than 3 ohms
4. All OK
