What's the reason for no response when starting the Howo key?
2 Answers
Reasons for no response when starting the Howo key: 1. First, check if the battery has power. If the car battery is completely drained, an external power source is needed for a jump start. If the car can start through jump-starting, it indicates a battery power shortage. 2. Inspect the car's ignition system to see if the live wire entering the ignition switch has power. If there is power, the ignition switch is functioning normally; if not, the ignition switch may be faulty. 3. The car's steering wheel might have been accidentally locked, which can also prevent the car from starting. In this case, place one hand on the steering wheel and use the other hand to turn the car key back and forth. The car should start quickly. This situation is not a malfunction but merely a locked steering wheel. 4. Electrical circuit issues can also cause the car to not start or respond. Common faults include blown fuses, open circuits in the high-voltage coil, open circuits in the low-voltage circuit, detachment of the central ignition wire, leakage in the distributor rotor, or damaged spark plugs. 5. Incorrect gear position can also prevent the car from starting. For example, if the car is parked in reverse gear, it may not start.
If my HOWO vehicle's key doesn't respond when starting, I'll start by checking the simplest possibilities, such as insufficient battery power. If the vehicle hasn't been driven for a long time or the weather is cold, the battery can easily lose charge. Using a voltmeter to test it will give a clear indication. If the voltage reading shows below 12 volts, it's necessary to recharge or jump-start the battery. Next, I'll examine the key itself. Many HOWO models now come with smart keys, and when the key battery is nearly depleted, it might fail to detect the signal, preventing the vehicle from starting. In this case, replacing the key battery or trying a spare key might help. Sometimes, the anti-theft system can also lock up, requiring pressing the unlock button to reset it. If there's still no response, I'll open the hood to check the fuses. Blown fuses are quite common, so locating and replacing the corresponding fuse in the fuse box is necessary. Lastly, issues with the ignition switch or starter motor can also cause this problem, where the vehicle makes a humming sound but doesn't start. Safety comes first—avoid forcing the operation and consider taking the vehicle to a repair shop for a comprehensive inspection. Regular maintenance can help reduce the occurrence of such issues.
