How to fix it

  1. Reseat all harnesses between main and motor control boards.
  2. Inspect harness routing for chafing; re-tape or re-route.
  3. Look for bulged or leaking capacitors on the MCU.
  4. Swap MCU; recheck.

  • Marginal connector contact Oxidized pins on inter-board harness.
  • Failing MCU Capacitors on motor board drying out.
