What does the small wrench on the dashboard mean?

The appearance of a "small wrench" on the dashboard is simply a maintenance reminder. The vehicle's maintenance cycle is pre-set during manufacturing, so this symbol appears at certain mileage intervals to remind the driver to perform timely maintenance. Typically, the maintenance cycle is every 5,000 to 8,000 kilometers driven, with factory settings often exceeding 8,000 kilometers. Method to reset the "small wrench" indicator: Insert the key (do not turn it); hold down the trip meter reset button for 5-10 seconds while turning the ignition to the "ON" position; wait another 5-10 seconds before starting the engine. Maintain pressure on the reset button throughout this process. Usually, these steps will clear the wrench symbol. If unsuccessful, repeat the procedure several times.

What are the reasons for the ABS light coming on in a Baojun vehicle?

ABS light can illuminate in various states, with different causes and solutions for each state, as detailed below: State 1: ABS warning light remains constantly lit (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS control unit from determining the vehicle speed and the wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections in the system wiring or poor contact in the ABS relay, leading to system failure. Solution: Inspect the wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates, but turns off during acceleration. Cause: When multiple vehicle electrical devices are in use, 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 power supply voltage is too low, possibly due to poor terminal contact 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 remains lit after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body wiring connector; ABS control unit 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 control unit. State 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS control unit detects a significant discrepancy between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal, push the brake switch linkage down fully with a finger, then release the brake pedal to complete the self-setting position; replace the brake light switch. If the ABS warning light is on, it is advisable not to continue driving. An illuminated ABS light indicates a fault in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's trajectory, posing significant safety risks.

What are the differences between vehicle air recirculation and fresh air mode?

The differences between vehicle air recirculation and fresh air mode are as follows: 1. Different working principles: Recirculation means the air inside the vehicle is heated or cooled and then recirculated back into the cabin; Fresh air mode draws outside air into the vehicle after heating or cooling it, achieving air exchange between the interior and exterior. 2. Different usage methods: When initially turning on AC cooling or heating, you can first activate recirculation to quickly lower or raise the cabin temperature; After temperature stabilizes, appropriately switch to fresh air mode for ventilation; Avoid using fresh air mode when outside air quality is poor, such as in heavy traffic with exhaust fumes or poorly ventilated underground parking. When driving on highways, never open windows - simply use fresh air mode instead. When outside air is clean but the cabin feels stuffy, promptly switch to fresh air mode for ventilation.

What are the effects of a faulty oxygen sensor on a car?

The effects of a faulty oxygen sensor on a car include excessive emissions, deterioration of engine conditions, leading to symptoms such as stalling at idle, inaccurate engine operation, and decreased power. More information about oxygen sensors is as follows: 1. There are two oxygen sensors: the front oxygen sensor, located at the exhaust manifold, is used to adjust the mixture concentration; the rear oxygen sensor, located behind the three-way catalytic converter, is used to monitor the working condition of the three-way catalytic converter. 2. Replacement cycle of oxygen sensors: Oxygen sensors do not have a fixed replacement cycle, but it is recommended to replace the oxygen sensor for vehicles with over 100,000 kilometers.

Does shifting into P gear before the car comes to a complete stop have any impact?

It can cause damage to the car. In principle, the output shaft of the automatic transmission is still rotating before the car comes to a complete stop. Directly engaging the P gear mechanically meshes the parking pawl with the brake gear, forcibly fixing the output shaft at its rotational speed, which creates a mechanical impact on the parking pawl and brake gear. The specific details are as follows: 1. Although there is an impact, it won't cause significant damage or part failure. However, if the speed is high, it might break the gear, leading to a major malfunction. The internal structure of an automatic transmission is very expensive to maintain precisely, and it's almost impossible to restore it to its original condition after a major overhaul. 2. If the P gear is engaged before the vehicle comes to a complete stop, the parking pawl and ratchet wheel in the transmission can be damaged. As long as the vehicle can still drive normally, it means the transmission hasn't suffered fatal damage. However, when using the vehicle, it's strictly prohibited to engage the P gear before coming to a complete stop, as doing so multiple times can cause significant damage to the transmission. The correct procedure for automatic parking is to first press the brake, shift into N gear to come to a smooth stop, then engage the handbrake, release the foot brake, turn off the engine, and finally shift into P gear and remove the key.

What does EPS mean on a car?

EPS on a car stands for Electric Power Steering system, which uses the power generated by an electric motor to assist the driver in steering. The structural components of EPS vary depending on the vehicle. Relevant information about EPS is as follows: 1. Composition: It generally consists of a torque sensor, electronic control unit, motor, reducer, mechanical steering gear, and battery power source. 2. Function: When a car is subjected to lateral and longitudinal forces during driving, excessive lateral force can significantly reduce the steering force, making it easy to lose control. EPS, based on CPU calculations when the vehicle shows unstable tendencies, can independently apply braking to each wheel and participate in the management of the engine system to ensure driving safety.
