Haval h2 throttle matching method

Matching method of electronic throttle

1, turn the key to the power position, and do not start it.

2. Let it stand for about 10 second, quickly step on the accelerator pedal to the bottom, hold it for 15 second, and then quickly lift the pedal.

3. Close the key door, take out the key and let it stand for about 15 seconds.

4. Start the car normally.

Matching is complete.

The above is the manual matching method of most electronic throttles, which is basically universal. The principle is to use the adaptive learning function of the computer. If the first collocation is not ideal, you can repeat it several times.

1. Common faults of low-voltage circuit: insufficient battery storage capacity; Poor or chaotic wire connection; Poor battery grounding; The distributor or Hall sensor is damaged; The ignition switch is damaged or poorly wired; The transistor ignition control unit is damaged or poorly wired. The fault diagnosis methods of low-voltage circuits mostly use ammeter or voltmeter to check line by line to eliminate fault points.
