Wall Connector Loose or Damaged Wiring causes Tesla Alert CC_a001

Tesla Wall Connector Loose Wiring

No ground connection detected in the Wall Connector may trigger symptoms such as the alert Tesla CC_a001 and the Wall Connector blinking red in

sets of two blinks.

This cause involves physical degradation or mechanical failure of the ground wire path. Diagnosis requires a professional inspection of the terminal block inside the Wall Connector and all upstream connections at the circuit breaker or power distribution box to identify loose, oxidized, or severed connections that prevent a continuous path to the earth.
