GAC Honda's OBD interface is located on the lower left side of the dashboard in the driver's seat. Introduction to OBD: OBD stands for On-Board Diagnostics, which can detect the working conditions of the engine and other components during vehicle operation. OBD monitors the engine, catalytic converter, particulate filter, oxygen sensor, emission control system, fuel system, EGR, and other systems and components in real-time. It then connects to the ECU through information related to different emission-related components. When an emission fault occurs, the ECU records the fault information and related codes and issues a warning through the fault light to inform the driver. Function of OBD: This system continuously monitors whether the vehicle's exhaust exceeds the standard during engine operation and issues an immediate warning if it does. When a system fault occurs, the Malfunction Indicator Lamp (MIL) or Check Engine warning light will illuminate, and the Powertrain Control Module (PCM) will store the fault information in memory. The fault code can be read from the PCM through a specific procedure. Based on the fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault.

Which is Better: Hybrid or Plug-in Hybrid?

Plug-in hybrid is better. Plug-in hybrid vehicles are more fuel-efficient and can also benefit from national new energy subsidies. Below is a detailed comparison of the two: 1. Plug-in hybrid vehicles (PHEV, plug-in hybrid electric vehicle) are a necessary transition from new energy vehicles to pure electric models and represent one of the future trends in automotive development. Equipped with a battery pack and electric motor, their most notable feature is the presence of a charging port for external charging. Currently, these vehicles can typically travel about 50 kilometers in pure electric mode, which is sufficient for urban commuting. They have larger battery capacities, and the electric motor directly participates in driving, serving more than just an auxiliary role as in conventional hybrid vehicles. 2. Conventional hybrid vehicles have smaller battery capacities and can only recharge the battery through the normal operation of the engine. The battery's primary function is to start the vehicle, assist in acceleration, and so on. Beyond a certain speed, the engine takes over to propel the car. Since starting and rapid acceleration are the most fuel-intensive operations, the electric motor's intervention effectively addresses this issue, resulting in relatively low fuel consumption.

What to Do When Car Windows Freeze in Winter?

Here are solutions for dealing with frozen car windows in winter: 1. Turn on the heating system: There are two types - manual and automatic air conditioning. For manual air conditioning, first rotate the temperature knob to the lowest position in the red zone, setting the heater to maximum heat. Then turn the air mode button to the windshield defrost position. Next, turn off the internal circulation button and set the fan speed to level 4 or higher - the higher the speed, the faster the ice will melt. For automatic air conditioning, simply select the front window defrost button on the console, and the system will automatically adjust to higher temperature with maximum airflow. 2. De-icing tools: In colder regions where the windshield freezes daily before driving, consider purchasing de-icing tools like frost scrapers. These small tools can be more efficient and effective. 3. Automotive glass de-icer: This is a special antifreeze concentrate designed specifically for thawing frozen windows and wipers, which won't damage the car's surface. It can effectively prevent window freezing even without using the car's heating system. If ice has already formed, simply spray the de-icer on the inner surface of the car window and wipe it clean.

What are the benefits of cleaning the throttle body?

Cleaning the throttle body mainly has the following three benefits: 1. Reduce fuel consumption: If the throttle body is excessively dirty, it may cause poor engine acceleration and increase fuel consumption. Regular cleaning of the throttle body can reduce a lot of unnecessary fuel consumption. 2. Improve fuel efficiency: Cleaning the throttle body can enhance air intake and fuel injection accuracy, thereby improving fuel efficiency and ensuring optimal fuel utilization, avoiding waste. 3. Extend engine lifespan: Cleaning the throttle body can reduce engine wear, making the engine more durable. Relevant information about the throttle body is as follows: 1. Definition of the throttle body: The throttle body is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. 2. Positioning of the throttle body: The throttle body is one of the most critical components in modern fuel-injected engine systems. Its upper part connects to the air filter (air box), and the lower part connects to the engine block, making it essentially the "throat" of the car engine.

Can You Continue Driving When the ABS Light Is On?

ABS fault light is on, it is recommended not to continue driving, because the ABS light on means the vehicle's anti-lock braking system is faulty. During emergency braking, if the wheels lock up, the vehicle may lose control and skid, making it impossible for the driver to slow down or adjust the vehicle's trajectory, posing significant safety hazards. There are various states of the ABS light being on, and the causes and solutions differ for each state, as detailed below: State 1: ABS fault light stays on (most common). Cause 1: The sensing part of the ABS speed sensor is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the speed and the wheel's slip rate, thus unable to issue appropriate commands to regulate braking. Solution: Clean the dirt on the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections between system lines or poor contact of the ABS relay, leading to system failure. Solution: Check the line connections and reconnect any loose parts. State 2: ABS warning light intermittently turns on and off, extinguishing when accelerating. Cause: When multiple vehicle electrical devices are used, the battery voltage drops below 10.5V. As the engine speed increases, the voltage rises, and the ABS indicator light turns off; the ABS system's power supply voltage is too low, such as due to poor contact at terminals or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start until the engine is turned off. Cause: Poor contact in the ABS hydraulic valve body's grounding circuit; poor contact in the ABS hydraulic valve body's wiring connector; ABS computer failure. Solution: Loosen the grounding screw of the hydraulic valve body, then retighten it, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. State 4: ABS warning light turns on during high-speed driving. Cause: During high-speed driving, the ABS computer calculates that the rear wheel speed differs significantly from the front wheel speed; incorrect tire specifications or incorrect wheel rim specifications. Solution: Refer to the vehicle's tire specifications and wheel rim specifications, as indicated on the sticker near the fuel tank cap. State 5: ABS warning light intermittently turns on and off. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: Start the engine, press the brake pedal, push the brake switch linkage down to the bottom with your finger, then release the brake pedal to complete the self-setting position; replace the brake light switch.
