Troubleshooting Steps:

  • Inspect cable connections by unplugging and replugging them. Look out for any cuts, bends, or plug damage.

  • Unplug and inspect the cable between the crank (PAS sensor) and the controller.
  • Reconnect and perform a factory reset on the display.

Check PAS sensor cable and connector
