Charger Door Ajar Indicator Malfunction

The hybrid powertrain control module 2 provides a 5V signal through a pull-up resistor to the Charge Port Door Position Sensor Circuit. The other end of the Charge Port Door Position Sensor Circuit is connected to the Charge Port Door Position Switch. The hybrid powertrain control module 2 monitors the voltage on the Charge Port Door Position Sensor Circuit. In normal operation, the hybrid powertrain control module 2 sends a serial data message to the driver information centre in the instrument panel cluster to display the Charge Door Open message.

Vehicle in Service Mode, observe the scan tool Charge Port Door parameter while opening and closing the charge port door, the value should change between Open and Closed.

1. Vehicle OFF, disconnect the harness connector at the B197 charge port door position switch.
2. Test for less than 10 Ω between the ground circuit terminal C and ground.

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

3. Vehicle in Service Mode, test for 4.75-5.25 V between the signal circuit terminal A 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 B197 charge port door position switch.

1. Vehicle OFF, disconnect the harness connector at the B197 charge port door position switch.
2. Test for 180 Ω--190 Ω between the signal terminal A and the ground terminal C with the switch in the open position.

⇒	If not within the specified range, replace the B197 charge port door position switch.

3. Test for 2040 Ω--2065 Ω between the signal terminal A and the ground terminal C with the switch in the closed position.

⇒	If not within the specified range, replace the B197 charge port door position switch.
