What is the relationship between the oil lamp and the left front door light?

Normally it is wood that is connected.

Start by checking the oil pressure. If the oil pressure is normal, the oil alarm light is still on, the cause of the fault is generally in the electrical circuit part, at this time the pressure switch, related circuits and alarm control unit should be checked, the specific methods are as follows: 1 Turn on the ignition switch, but do not start the engine, the oil alarm light should be on, if not, you can unplug the low-voltage switch plug to catch the iron, if the light is on, it means that the low-voltage switch is damaged and should be replaced; 2. Start the engine, idle running, the oil alarm light should be off, if the light is always on, unplug the low-voltage switch plug after the light is off, it means that the low-voltage switch is damaged, should be replaced, such as unplugging the low-voltage switch plug after the lamp is off, then there is a short-circuit fault in the line; 3. Stabilize the engine speed, if there is a beep when the alarm light is on, you can unplug the high-voltage switch plug (marked on the filter seat of the machine, white), and take the iron, if the alarm light is off, the alarm sound also disappears, indicating that the high-voltage switch is damaged and should be replaced. 4. If the high-voltage switch, low-voltage switch and related wiring are normal, it may be the fault of the oil alarm control unit, and the oil alarm control unit located on the dashboard can be replaced.

If the oil pressure is abnormal after checking and the oil alarm light is on, the oil pressure gauge installed at the low pressure switch can be removed, and the oil pressure can be measured at the high pressure switch. If the pressure is normal, it means that the oil passage from the cylinder block to the cylinder head is blocked; If the pressure is abnormal and lower than the specified value, it can be checked from the following aspects: 1 Check whether the oil is diluted, because the oil is too thin will also reduce the oil pressure, if the oil is too dirty, the oil and oil filter should be replaced; 2. Generally, vehicles with a driving distance of more than 80,000 km should be cleaned and checked for deformation of the oil pan and whether the oil pump filter is blocked during maintenance; 3. Check and clean the oil pump, clean the pressure regulating valve, and check the oil supply of the oil pump; 4. Clean and inspect each oil circuit.

The battery light and the oil lamp are lit at the same time, but also two faults, these two systems are not related at all, the battery light is on the engine does not generate electricity, which should take into account whether the generator belt is broken, or simply the generator itself is damaged, the replacement of the generator or the generator belt can be repaired, the oil lamp is on the lack of oil, that is, the engine can be solved by filling the engine with oil, the specific operation steps are as follows:

1. Open the door on this side of the cab.

2. Pull the hood switch on the left side of the driver's leg.

3. Lift the hood of the engine upwards.

Fourth, use support rods to support the engine hood.

5. Unscrew the oil cap and add the oil.

Happy lifeRegarding your inquiry, the oil alarm light is related to many factors, such as low oil level, oil plug failure, filter quality problems, low oil pressure, oil pump failure or oil plug circuit problems. This kind of fault needs to be comprehensively checked, first to check whether the oil level and oil pressure are normal, and secondly, to check the working condition of other components.

Hello: According to the phenomenon you described, it may be caused by the low engine idle speed, because these lights rarely light up at the same time, it is recommended that you focus on checking whether the engine idle speed is normal. Secondly, it may also be caused by improper operation, which should not be too much of a problem.

Antifreeze indicator to see if it's antifreeze.

Flammable and explosive signal lights, abandon the car alarm.

If you don't start these lights, they should be on, and if they don't light up, the bulb inside is broken, and the normal situation is that they are on when you just open the key, and they should be off after starting (if they don't go out, they mean that they are faulty). After the oil pressure alarm light is started, it means that the oil pressure is too high or too low; After the engine fault light is started, it indicates that the engine has a fault code; The charging indicator lights up after starting, indicating that the battery is not in the charging state. The warning light on the dashboard can be turned on for a short time if the yellow one is on (drive to the repair shop), and the red one will be turned on immediately, otherwise it will cause serious damage.

Before inserting the key, the driving computer has a self-test.

After getting into the car, it is still bright and it is a fault.

After the car goes off, it means that the self-test is normal.

It's very simple, you have to change the battery!
