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 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 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

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.

Action Taken When the DTC Sets

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

Conditions for Clearing the DTC

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

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. It may take up to 2 minutes for all vehicle systems to power down.

2. Test for less than 10 ohms between the low reference circuit terminal 6 and ground.

• If 10 ohms or greater

1. Disconnect the harness connector at the K114B hybrid powertrain control module 2

2. Test for less than 2 ohms in the low reference circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.

• If less than 2 ohms, replace the K114B hybrid powertrain control module 2.

• If less than 10 ohms

3. Vehicle in Service Mode, test for 4.8-5.2 V between the 5 V reference circuit terminal 3 and ground.

• If less than 4.8 V

1. Vehicle OFF, disconnect the harness connector at the K114B hybrid powertrain control module 2.

2. Test for infinite resistance between the 5 V reference 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 5 V reference circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.

• If less than 2 ohms, replace the K114B hybrid powertrain control module 2.

• If greater than 5.2 V

1. Vehicle OFF, disconnect the harness connector at the K114B hybrid powertrain control module 2, Vehicle in Service Mode.

2. Test for less than 1 V between the 5 V reference circuit and ground.

• If 1 V or greater, repair the short to voltage on the circuit.

• If less than 1 V, replace the K114B hybrid powertrain control module 2.

• If between 4.8-5.2 V

4. Test or replace the S113 charge port door open request switch.
