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 Common causes of matching failure include weak key signals, unstable vehicle voltage, or outdated diagnostic tool software versions, in which case you'll need to restart or check the vehicle's battery condition.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.
