Tesla Model 3: Charging equipment faultTry different charging equipment(CP_a004)

Tesla Model 3 2017-2023 Owner's Manual / Consumer Information / Troubleshooting Alerts / Charging equipment faultTry different charging equipment(CP_a004)

The charge port is unable to detect whether a charge cable is inserted or the type of charge cable connected.

If this alert appears while a charge cable is connected, it should be determined whether the issue is caused by the charging equipment or the vehicle. Try charging the vehicle using different external charging equipment (charge cable, charging station, charging stall, etc.).

  • If the vehicle begins charging, the issue was likely with the equipment.
  • If the vehicle still does not charge, the issue may be with the vehicle.

If this alert appears while a charge cable is not connected or if the issue is suspected to be with the vehicle, inspect the charge port inlet and the charge cable connector for any obstructions (use a flashlight as necessary).

Debris, moisture, and/or foreign objects present in the charge port inlet or the charge cable connector can prevent the charge port from properly detecting charge cables. If any obstruction is found:

  1. Remove the debris / foreign object or dry any moisture.
  2. Try re-inserting the cable into the charge port. Charging should now be possible.

Service should only be scheduled if any of the following conditions are present:

  • This alert has appeared / remains present and the vehicle has been unable to charge with multiple, different charging equipment.
  • This alert has appeared / remains present without any charging equipment connected after any charge port inlet obstruction has been removed or no obstruction was found.
