• Code: H3-00
• Description: Main heater lamp abnormally high temperature hard detection trouble
  The fusing main heater thermistor causes abnormally high temperature.
• Causes: Main heater lamp thermistor defect Control PWB failure Fusing section connector contact failure
• Remedy: Check the main heater lamp blinking with SIM 5-2-1. When the lamp blinks normally: Check the thermistor and the harness. Check the MCU PWB thermistor input circuit. If lamp lights and stays lit: Check the power circuit and the lamp control circuit on MCU PWB. Clear the display of self-diagnostics with SIM 14.
