Parking wood heating fault and troubleshooting method: 1, there is no reaction after the boot, the solution according to the circuit diagram to measure whether the heater power supply is normal, check the vehicle insurance and line power supply, check the power supply, check the boot signal line, check the ground; 2, the indicator light is steady on or blinking, the solution according to the flashing frequency of the heater indicator light against the fault flashing code table to determine the fault location, repair or replace the corresponding parts; 3, the heater black smoke, the solution heater carbon deposit, clean carbon deposit, fuel nozzle or filter or oil pipe blockage, cleaning or replacing the corresponding parts, oil pump pressure becomes smaller, return the oil pressure, if necessary, replace the oil pump; 4, the heater works normally, but repeatedly extinguisher, the hot spot couple in the heat of the internal furnace wire will be connected with the shell, causing the ignition sensor short circuit, the controller thinks that the fire extinguishing, the solution needs to replace the ignition sensor. 5, the ignition plug is damaged, use a multimeter to check the resistance value between the two leads of the ignition plug, the resistance value should be between 0.6-1.2 ohms, if not in this range, you need to replace the ignition plug. 6. The heater is overheated, the radiator and defroster are not hot, which may be foreign bodies blocked in the circulation pipeline; The hose is bent; Water pump failure; There is gas in the circulating waterway; The inlet and return water valve is not opened, the engine thermostat is opened too early, etc., find out the reasons for the corresponding maintenance.
