DTC Descriptor
DTC P0CD1 00
- Charge Port Door Unlock Control 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 closes. 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
The hybrid powertrain control module 2 is awake
Conditions for Setting the DTC
* The hybrid powertrain control module 2 detects a short to ground or an open/high resistance in the charge port door relay control circuit.
* The hybrid powertrain control module 2 detects an open/high resistance in the charge port door relay ground circuit
Action Taken When the DTC Sets
The charge port door latch will malfunction and the charge port door may not be able to be opened.
Conditions for Clearing the DTC
DTC P0CD1 00 is a type B DTC

Circuit/System Verification
1. Vehicle in Service Mode.
2. Verify the charge port door actuator releases the charge port door when commanding the charge port door to OPEN with the scan tool.
• If the charge port actuator does not release the charge port door
Refer to Circuit/System Testing.
• If the charge port actuator releases the charge port door
3. All OK.
Circuit/System Testing
1. Vehicle OFF, disconnect the KR119 charge port door relay. It may take up to 2 minutes for all vehicle systems to power down.
2. Test for less than 10 ohms between the ground circuit terminal 85 and ground.
• If 10 ohms or greater
1. Vehicle OFF.
2. Test for less than 2 ohms in the ground circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, repair the open/high resistance in the ground connection.
• If less than 10 ohms
3. Connect a test lamp between the control circuit terminal 86 and the ground circuit terminal 85.
4. Verify the test lamp turns ON when commanding the charge port door to OPEN with a scan tool.
• If the test lamp is always OFF
1. Vehicle OFF, disconnect the harness connector at the K114B hybrid powertrain control module 2.
2. Test for infinite resistance between the control 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, replace the K114B hybrid powertrain control module 2.
• If the test lamp is always ON
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 control 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 the test lamp turns ON and OFF
5. Test or replace the KR119 charge port door relay.
Component Testing
Relay Test
1. Vehicle OFF, disconnect the KR119 charge port door relay.
2. Test for 60-200 ohms between terminals 85 and 86.
• If less than 60 ohms or greater than 200 ohms
Replace the KR119 charge port door relay.
• If between 60-200 ohms
3. Test for infinite resistance between the terminals listed below:
* 30 and 86
* 30 and 87
* 30 and 85
* 85 and 87
• If less than infinite resistance
Replace the KR119 charge port door relay.
• If infinite resistance
4. Install a 3 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground.
5. Test for less than 2 ohms between terminals 30 and 87.
• If 2 ohms or greater
Replace the KR119 charge port door relay.
• If less than 2 ohms
6. All OK
