Unable to charge - Mobile Connector GFCI tripped
Unplug charge handle from charge port and retry
The vehicle cannot charge because the ground-fault circuit interrupter (GFCI) in the Mobile Connector has tripped.
Like the GFCI in a wall outlet, this feature is designed to stop the flow of electricity when there is a problem. It has interrupted
charging to protect your vehicle and the charging equipment.
This could happen for many reasons. The problem could be in the charge cable, the charge handle, the charge port, or even an
onboard vehicle component.
Inspect the charge port as well as the charge handle for pooled water or unusual levels of moisture.
• If you find excessive moisture, wait and let both the inside area of the charge port and the exposed portion of the charge
handle dry sufficiently before trying again.
Inspect the charge equipment for damage.
• If the cable is in any way damaged or deteriorated, do not use it. Try different charging equipment instead.
• If the cable is in good condition, try charging again with the same Mobile Connector.

• Inspect and clean the front camera area at the top center of the windshield before your next planned drive.
• Check the camera surface for condensation, dirt, or other debris and attempt to clear any obstruction.
See the About Autopilot on page 286 sections “How It Works” and “Cleaning Cameras and Sensors” for more information on
clearing dirt or debris from that area of the vehicle.
Although condensation on the inside of the front camera enclosure cannot be wiped clean, you can usually clear it quicker by
following these steps:
1. Pre-condition the cabin with the temperature set to High and A/C turned ON.
2. Turn on the front windshield defroster.
If this alert persists throughout subsequent drives but no front camera obstruction is visible, schedule service at your earliest
convenience. Your vehicle is OK to drive in the meantime.
