Why Won't the H6 Start When the Hill Descent Control Fails?

[OBrody]

Here are the main reasons why the H6 won't start when the hill descent control fails: 1. Excessive carbon deposits and dirt in the idle motor, intake tract, intake valve, and combustion chamber change the cross-sectional area of the air passage, resulting in an overly rich or lean mixture, causing abnormal combustion or engine shaking after starting, or even preventing the engine from starting. 2. Issues with the fuel injector, such as leaks or excessive carbon deposits, can cause the mixture to be too lean during startup, making it difficult to start. 3. A faulty carbon canister or carbon canister solenoid valve can also make starting difficult. Additional information: The solution to the H6 hill descent control failure is to take it to a 4S shop for repair. First, the fault code needs to be read to quickly determine the cause and location of the fault, and then the problem can be resolved based on the situation.
