How to Deal with Brake Failure at High Speed?

When experiencing brake failure at high speed, it is crucial to remain calm. First, release the accelerator pedal and reduce the vehicle's speed by downshifting, using the handbrake, or utilizing road resistance. Aim to stop in a safe area as soon as possible and wait for assistance. In the event of brake failure at high speed, the handbrake can be used for braking, but it must be operated properly. Avoid yanking the handbrake abruptly out of panic, as this could cause the handbrake cable to snap due to excessive force, rendering the handbrake ineffective or locking the rear wheels, which may lead to loss of vehicle control. The correct method is to gradually pull up the handbrake, alternating between tightening and releasing it several times to slow down and stop the vehicle. For manual transmission vehicles, forced downshifting can also be used to decelerate and stop. The specific approach is to shift directly into second gear, then release the accelerator and lift the clutch. This will create a sensation similar to sudden braking. Subsequently, shift into first gear when appropriate, and you can turn off the ignition to utilize the engine's cylinder compression to bring the vehicle to a halt.

Should I shift to P or N gear when waiting at a traffic light?

When waiting at a traffic light, shift to N gear and engage the handbrake. The N gear disconnects the engine from the transmission, and the passive wheel of the torque converter in the transmission is also in an idle state. At this time, it will not increase the resistance of the active wheel connected to the engine, and fuel injection will be reduced, making it relatively more fuel-efficient. However, to prevent the car from rolling, you must step on the brake or engage the handbrake. When the vehicle is shifted to P gear, the locking plate will engage the transmission gear, putting it in a mechanically locked state. If a rear-end collision occurs at this time, the transmission will be damaged, and severe impact may even cause the gear to break directly. Therefore, shifting to P gear is not advisable.

What does the OBD light mean?

OBD light is the On-Board Diagnostics system, displayed on the dashboard as a wrench-like symbol, also known as the engine malfunction indicator light. The primary function of OBD is to continuously monitor whether the vehicle's exhaust emissions exceed the standard limits. If they do, it will immediately issue a warning. The OBD interface can provide various operational data of the vehicle, including but not limited to fuel consumption records, battery voltage, air-fuel ratio, etc., in addition to the data displayed on the vehicle's dashboard. When a system fault occurs, the malfunction indicator light or check engine warning light will illuminate, and the OBD system will store the fault information in its memory. This information can be read in the form of diagnostic trouble codes (DTCs) through standard diagnostic tools and interfaces. Based on the DTCs, maintenance personnel can quickly and accurately identify the nature and location of the fault.

What does the EPC light indicate?

EPC light primarily indicates an electronic throttle system malfunction. The reasons for this light to illuminate include: 1. Intake system failure, such as leaks or blockages; 2. Dirty throttle body with excessive carbon buildup; 3. Use of substandard fuel; 4. Abnormal cylinder pressure, poor operating conditions; 5. Sporadic faults, false alarms; 6. Valve malfunction, sticking; 7. ECU failure. Solutions for EPC light illumination: 1. Troubleshoot intake system issues, use qualified fuel, clean the throttle body; 2. Remove carbon deposits from relevant parts; 3. Rewrite ECU-related data. If the EPC light comes on without obvious vehicle malfunction symptoms and the vehicle can still operate, the driver may attempt to turn off and restart the engine to reset the EPC light.
