If your Snugger Heater displays Error Code 2, it indicates a low voltage issue. Inspect the power lines from the heater to the battery and all connections for damage, corrosion, or looseness. Also, verify the voltage supply to the heater and inspect the vehicle's charging system and voltage regulator.
