What does 36 mean?

An alarm indicating excessive battery drain has been triggered, suggesting a higher than normal current draw. This condition limits the drive speed.

Common Causes

  • High current draw from the battery, possibly due to an electrical load or system inefficiency.
  • Internal fault in a connected electrical component causing parasitic drain.
  • Aging battery with reduced capacity and increased internal resistance.
