Nissan Contactor Chatter / Failed Start Sequence

Nissan EVSE wallbox makes a clicking sound repeatedly every few seconds without starting a charge.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Unstable pilot signal causing repeated start/stop, Weak contactor coil voltage, Control board firmware glitch, Vehicle repeatedly rejecting handshake

Safety first: Repeated contactor operation can cause wear. Turn OFF the breaker if the behavior continues.

Power-cycle both EV and EVSE: Turn off the charger breaker and power down the vehicle (lock and wait). Restore power and retry.
Inspect wiring: With power OFF, check control wiring to the contactor coil for loose connections.
Test with another vehicle: Determine if the issue is vehicle-specific.
Firmware update: Check with Nissan support for any firmware updates addressing handshake issues.
