Select the Delphi Body Control System under the Body Control System, and choose to read the fault codes, which display 4 faults. It indicates that the tire pressure sensors for the front left, front right, rear left, and rear right tires have not been learned. Select the tire pressure sensor learning option. It prompts to wait for 60 seconds. When the activation is successful, there will be a 'beep' sound, and the X431 diagnostic software will also indicate a successful activation.
As an automotive repair technician, I frequently assist car owners with immobilizer system matching. The key method for programming the Great Wall Haval H6's immobilizer using the 431 diagnostic tool involves reprogramming new keys or resetting the system. First, turn the car key to the ON position without starting the engine, then connect the X-431 diagnostic scanner to the OBD port. In the device menu, select the Great Wall Haval H6 model and access the immobilizer system function module. Next, follow the prompts to input the new key's ID code, or if the original owner's key is available, use it as a reference key for synchronization. During the matching process, the device will display the status—it's crucial to patiently wait for completion confirmation without interrupting power or disconnecting. Common causes of matching failure include weak key signals, unstable vehicle voltage, or outdated diagnostic tool software versions, in which case you'll need to restart or check the vehicle's battery condition. Overall, this method proves highly effective for the H6's immobilizer module but requires professional tools and experience to avoid system lockout. I recommend owners prepare spare keys before attempting DIY to prevent complications.
I love tinkering with my car in my spare time. Last week, I just used a 431 scanner to match the anti-theft key for my Great Wall H6. The process wasn't too difficult, provided you have the right equipment. I borrowed the device from a repair shop, plugged it into the OBD port, selected the H6 model menu, and clicked on the anti-theft matching option. Then it prompted me to enter the new key serial number or scan the original car key. I took my time to ensure the signal was stable and avoided any phone interference. It was done in less than 10 minutes. The tricky part is that first-time users might make mistakes, such as selecting the wrong model year or not placing the key in the correct position, leading to non-recognition. After succeeding once, I learned a lesson: make sure the vehicle is parked safely before matching, preferably in a garage. If the issue persists, it might be due to a damaged anti-theft chip, requiring a new key replacement. DIY saves money, but if you're unsure, it's safer to visit a professional shop.
I'm a car repair enthusiast, sharing a simple method for matching the Great Wall H6's anti-theft system using the 431 device. Connect the 431 diagnostic tool to the car's OBD port, select the H6 model after powering on, enter the anti-theft module, and execute the matching procedure. The key steps involve entering key information or inserting the original car key for confirmation, then waiting for the device to feedback a success signal. Avoid touching anything else during the process and focus on completing it.
