DTC P0CD1

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 energised which then allows B+ voltage to the charge port door latch which activates and releases the charge port doorr.

The hybrid powertrain control module 2 is awake

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

DTC P0CD1 00 is a type B DTC

Vehicle in Service Mode, command the charge port door to OPEN with the scan tool, the M80 charge port door actuator should release the charge port door allowing it to open.

1. Vehicle OFF, disconnect the KR119 charge port door relay.
2. Test for less than 1 Ω between the ground circuit terminal 85 and ground.

⇒	If greater than the specified range, test the ground circuit for an open/high resistance.

3. Connect a test lamp between the control circuit terminal 86 and ground.
4. Vehicle in Service Mode, command the charge port door to OPEN with a scan tool. The test lamp should turn ON during the OPEN command.

⇒	If the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal, replace the K114B hybrid powertrain control module 2.

⇒	If the test lamp is always OFF, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K114B hybrid powertrain control module 2.

5. If all circuits test normal, test or replace the KR119 charge port door relay.

Relay Test

1. Vehicle OFF, disconnect the KR119 charge port door relay.
2. Test for 60-180 Ω between terminals 85 and 86.

⇒	If not within the specified range, replace the KR119 charge port door relay.

3. Test for infinite resistance between the following terminals:

•

30 and 86

•

30 and 87

•

30 and 85

•

85 and 87

⇒	If not the specified value, replace the KR119 charge port door relay.

4. Install a 5 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground. Test for less than 2 Ω between terminals 30 and 87.

⇒	If greater than the specified range, replace the KR119 charge port door relay.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
