Why does the Civic fail to start and display a 'Check Brake System' message?
1 Answers
The Civic failing to start and displaying a 'Check Brake System' message can be attributed to the following main reasons: 1. Excessive carbon deposits in the idle speed motor, intake tract, intake valve, and combustion chamber: Too much carbon buildup or dirt in the intake tract alters the cross-sectional area of the air passage, resulting in an overly rich or lean air-fuel mixture, causing abnormal combustion or engine shaking after startup, or even preventing the engine from starting. 2. Issues with the fuel injector: Leakage or excessive carbon deposits can lead to a lean air-fuel mixture during startup, making it difficult to start. 3. Malfunction of the carbon canister or carbon canister solenoid valve: This can also cause difficulty in starting.
