What are the indicator lights on the truck dashboard?

The illustration of the fault light indicator light of the truck dashboard helps drivers quickly identify vehicle faults and ensure driving safety. The red fault light indicates an emergency and needs to be stopped for immediate inspection; the yellow warning light reminds you of potential problems, and it is recommended to overhaul it in time.

The red icon, a rectangle, with the letter LIM inside, represents speeding. The red icon (some models are yellow), a triangle with an exclamation mark in it, representing the central warning light. The red icon, the graphic of a truck, represents the ECAS electronically controlled air suspension.

Water temperature indicator light The water temperature indicator light mainly displays the temperature of the coolant in the engine. It is only lit for a few seconds during the vehicle's self-inspection, and is usually turned off. Usually, we often hear the so-called engine "opening", which means that the coolant temperature exceeds the specified value. At this time, the operation should be suspended immediately for maintenance.

How to deal with the yellow light of the engine fault light?

The following is the launchHow to deal with the yellow light of the machine 1 When the engine fault light on the dashboard is on, you can try to start and turn off the vehicle three times in a row, or turn off the engine and remove the negative pole of the engine battery, wait for 30 seconds to connect it, and then try to start it according to the above method to see if the engine fault light on the dashboard is returned.

How to deal with the yellow light of the car engine fault light: check the engine in time and find a vehicle repair shop for maintenance. The yellow light on the dashboard lights up during the use of the vehicle, indicating that the vehicle engine needs to be maintained.

It will be sucked into the cylinder by the vacuum suction of the engine and burned, making the mixture thick. The combustible mixture of the engine is thin and thick, causing idle jitter. The solution is to clean the oil line and check whether the idling motor has carbon. The yellow light of the engine is to remind the car owner to go to the maintenance station to check the engine pollution emission light.

How to eliminate the yellow light of the engine? Repeat the operation of starting and turning off the engine three times. You can also choose to unplug the negative pole of the battery, and then plug it in for about 30 seconds to restart the engine.

What is the reason for the engine fault light in the car? What's wrong with the yellow light on the car engine

1. If any component of the engine emission system fails, such as oxygen sensors, catalytic converters, etc., it may cause the engine fault light to turn on. For the emission system, you'd better go to the 4S store to find a professional master to have a look. Engine mechanical failure: Mechanical failure inside the engine may also cause the engine failure light to light up.

2. There are many reasons why the car engine fault light is on, including poor quality of gasoline, oxygen sensor failure, air flow sensor failure, spark plug carbon accumulation, engine explosion, water temperature sensor damage, etc.

3. The yellow light of the engine is a gap fault of the engine, which indicates that the engine control system has detected the engine working condition or a sensor signal is out of time. At this time, the engine should be checked in time and the nearest vehicle repair shop for maintenance, because the engine is the heart of the vehicle, and it should be determined in time. Period maintenance.

4. The causes of engine failure include sensor problems, maintenance problems, oil quality problems, etc. Sensors include water temperature crankshaft position, air flow, intake temperature, oxygen sensor, etc. When this type of sensor is damaged, the ECU will send a signal, and the engine failure light will turn on at this time. Bright.

5. If the car engine fault light is yellow, you need to check the cause of the fault light and eliminate it. If the engine fault light is yellow, it means that there is a problem with some parts of the vehicle engine, due to parking and inspection; if the engine fault light is red, you need to stop immediately and contact the repair shop for road support and help.

6. Poor combustion of the engine is the key reason why the engine is on. The reasons why the engine light on the dashboard of the car is yellow are: poor quality of gasoline; failure of oxygen sensor and air flow sensor; spark plug carbon accumulation; engine explosion; water temperature sensor damage; engine lack of cylinder.
