Possible Causes

Worn latch mechanism in J1772 handle, Deformed connector housing, Loose vehicle inlet on car, Contaminated or oxidized contacts

How to Fix / Troubleshooting

Safety first: Do not force the connector; damage can worsen.

  • Inspect latch and housing: Check that the latch fully engages and that the handle seats completely in the vehicle inlet.
  • Clean contacts: Use contact cleaner on the handle pins and vehicle inlet. Allow to dry fully.
  • Test on another vehicle: If the issue only occurs on one car, the vehicle inlet may be worn and require service.
  • Replace handle/cable: If the handle is visibly worn or deformed, replace the J1772 output cable and handle assembly.
