Turn on the ignition without starting the engine.
Retrieve and document any error codes related to the stalling issue.

3. Inspect and Repair Battery and Connections

Reconnect the 12V battery.
Open the trunk and access the high-voltage battery compartment.
Inspect the battery for any visible damage or corrosion.
Ensure all connections are tight and free from corrosion. Clean if necessary.

4. Test Throttle Position Sensor

Disconnect the throttle position sensor electrical connector.
Use a multimeter to check the resistance across the sensor terminals while moving the throttle plate.
If readings are outside of the specified range in the service manual, replace the sensor.

5. Software Update

Check the vehicle's software version using the touchscreen interface.
If an update is available, follow the manufacturer's instructions to perform the update.
Restart the vehicle after the update is completed.
