2021 TESLA MODEL Y sensor

Continue to your destination. Your vehicle is OK to drive.
This is often a temporary issue that will be resolved when condensation evaporates or a particular environmental
condition is no longer present.
If the alert does not clear by the time you reach your destination, check camera surfaces for condensation, dirt, or
other debris.
For camera locations, see About Autopilot on page 83.
Clean the cameras as necessary before your next planned drive. For recommended cleaning procedures, see
Cleaning Cameras and Sensors on page 85.
If you continue to see this alert after cleaning the cameras, check the inside surfaces of the door pillar camera
enclosures for condensation.
Although condensation inside the camera enclosures cannot be wiped clean, you can usually clear it faster 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.
3.
Direct the air vents toward the door pillar cameras.
For more information on clearing condensation from camera enclosures, see Cleaning Cameras and Sensors on page
85.
If the alert does not clear by the end of your next planned drive, despite cleaning the indicated camera(s) and
following recommended steps to clear condensation, schedule service at your next convenient opportunity. Your vehicle is OK to drive in the meantime.

Unable to charge - Incorrect switch setting
Wall Connector rotary switch must be adjusted
What this alert means:
Incorrect rotary switch setting.
What to do:
Make sure there is no power to the Wall Connector. Remove the face plate and adjust the rotary switch to a valid
operating current setting. The correlation between switch setting and current is printed on the inside of the Wall
Connector. You can also refer to the Set the Operating Current section in the Wall Connector Installation Manual. If
the Wall Connector is set up for load sharing (paired with other Wall Connectors), the rotary switch of the master
unit must be set to an operating current setting that allows each paired Wall Connector to receive at least 6A of
charge current. Example: Three Wall Connectors are paired for load sharing. The master unit needs to be set to a
current of at least 3 * 6A = 18A or greater.

Charge port door sensor fault
Charge port may not operate as expected
One of the charge port door sensors is not functioning normally. When this occurs, the charge port may be unable to
accurately sense the charge port door position and the charge port may not operate as expected.
