Common Symptoms

  • Alert on the touchscreen: "Charging stopped - Charge cable disconnected — Close charge port - Press brake pedal and retry"
  • A charging session ends before the target charge level is reached
  • Typically appears right after a cable was pulled without stopping the session first
  • Driving is unaffected

Probable Causes (Ranked by Likelihood)

  • The connection between the charge port and the charge cable was interrupted mid-session — most commonly the cable was disconnected without stopping charging first Likely
  • A loose or intermittent cable connection interrupting the session Possible

Step-by-Step Diagnostic Procedure

  1. Per Tesla's official guidance: always stop charging before disconnecting the cable — via the button on the charge handle (on some equipment), the vehicle touchscreen, the Tesla app, or the charging station.

  2. To resume charging, close the charge port, press the brake pedal, and reconnect the cable.

  3. If sessions keep getting interrupted without anyone touching the cable, check that the cable is fully seated and latching properly (see CP_a054), and try different equipment to rule out the charger.

Frequently Asked Questions

What does CP_a056 mean on a Tesla?

Tesla's official meaning: charging stopped because the vehicle detected that the connection between the charge port and the charge cable was unexpectedly interrupted — usually because the cable was unplugged without stopping the session first.

How do I avoid CP_a056?

Stop charging before unplugging: press the button on the charge handle (where equipped), or stop the session from the touchscreen, the Tesla app, or the charging station. Then disconnect the cable.
