What You May Notice

  • Vehicle will not start — you hear rapid clicking but nothing engages
  • Tesla app shows vehicle non-operational
  • Charging may have been interrupted just before this alert appeared

How to Diagnose and Resolve

  1. 1 Do not repeatedly try to start — each failed precharge attempt can stress components
  2. 2 Wait 10 minutes, then try a single reboot: hold brake + scroll wheels
  3. 3 Check 12V battery — low 12V can cause precharge failures
  4. 4 If still non-operational, arrange flatbed tow to Tesla Service Center
  5. 5 Technician will test the precharge circuit and resistor
