Volt

DTC P0CC7, P0CC9, or P0CCA

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 switch contact closes and provides B+ voltage to the wake--up signal circuit. 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

P0CC7 00

The hybrid powertrain control module 2 detects high resistance or an invalid high or invalid low voltage in the in the charge port door open request switch circuit.

P0CC9 00

The hybrid powertrain control module 2 detects a short to ground or an open/high resistance in the charge port door open request switch circuit.

P0CCA 00

The hybrid powertrain control module 2 detects a short to voltage in the charge port door open request switch circuit.

The charge port door will malfunction and the charge port door may not be able to be opened.

DTC P0CC7 00, P0CC9 00 and P0CCA 00 are type B DTCs

Control Module References for scan tool information

Vehicle in Service Mode, command the M80 charge port door actuator to UNLATCH with the scan tool, the M80 charge port door 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. Test for less than 10 Ω between the low reference circuit terminal 6 and ground.

⇒	If greater than the specified range, test the low reference circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the K114B hybrid powertrain control module 2.

3. Vehicle in Service Mode, test for 4.75 -- 5.25 V between the signal circuit terminal 3 and ground.

⇒	If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K114B hybrid powertrain control module 2.

⇒	If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K114B hybrid powertrain control module 2.

4. If all circuits test normal, test or replace the S113 charge port door open request switch.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
