(CP_a054) Charge port latch not engaged Fully insert charge cable or check for obstruction

Post by TeslaKingLong »

The charge port latch is unable to latch the charge cable in the charge port inlet. If the latch is not engaged, AC charging (for example, charging with a Tesla Mobile Connector or Wall Connector) will be limited to 16A and DC Fast Charging / Supercharging will be unavailable. The charge port light will pulse amber if this alert appears during AC charging and will be solid amber if this alert appears when attempting to DC Fast Charge / Supercharge.

Try re-inserting the charge cable fully into the charge port inlet.

• If the vehicle begins charging and the charge port light pulses green, the charge cable may not have been fully inserted. The latch may not have engaged during previous attempts, because the cable was not fully inserted, even though it may have appeared to be. AC charging should no longer be limited and DC Fast Charging / Supercharging should be possible.

• If charging is still limited or the vehicle does NOT charge, inspect the charge port inlet and the charge cable connector for any obstructions (use flashlight as necessary). Debris, and/or foreign objects present in the charge port inlet or the charge cable connector can prevent the charge cable from being fully inserted and the charge port latch from engaging. If any obstruction is found:

1. Remove the debris / foreign object.

2. Try re-inserting the cable into the inlet. AC charging should no longer be limited and DC Fast Charging / Supercharging should be possible. As this alert is usually specific to external charging equipment and power sources, and it does not typically indicate an issue with your vehicle that can be resolved by scheduling service, it is recommended that you:

• Make sure the charge cable is fully inserted during charging.

• Make sure any charge port inlet obstruction has been removed.
