Powertrain-related issues -
**Question**: What could be the reasons for insufficient engine power? -
**Answer**: It might be that the air filter is clogged, resulting in insufficient air intake. In this case, you need to clean or
replace the air filter. It could also be that the fuel filter is clogged or there is a problem with the fuel pump, causing an
obstruction in the fuel supply. You'll need to check and replace the fuel filter or repair the fuel pump. Additionally, carbon
deposits on or malfunction of the fuel injectors might affect the fuel injection effect, requiring the fuel injectors to be
cleaned or replaced. -
**Question**: What should I do if the engine malfunction light comes on? -
**Answer**: First, park the vehicle safely and check whether there are any obvious abnormalities in the engine, such as strange
noises or smoke. Then use a professional diagnostic device to read the fault codes and conduct troubleshooting according to the
prompts of the fault codes. It could be a sensor malfunction, a wiring problem, or a failure of internal engine components. For
example, if the fault code is 415, which indicates low oil pressure, you need to check the oil level and the oil pump.
### Transmission-related issues -
**Question**: What causes rough or jerky shifting? -
**Answer**: If it's a manual transmission, it might be that the clutch disc is severely worn and needs to be replaced. It could
also be that the shift cable is improperly adjusted and needs to be readjusted. If it's an AMT transmission, it might be that the
transmission fluid level is too low or the fluid has deteriorated. In this case, you need to check and replenish or replace the
transmission fluid. It could also be an electrical control system malfunction, which requires inspection and repair at a
professional maintenance shop. -
**Question**: How can I solve the problem of abnormal noise from the transmission? -
**Answer**: First, check whether the transmission fluid is sufficient and of normal quality. If the fluid is okay, it might be
that the gears are severely worn, the bearings are damaged, or there is a problem with the synchronizer. In this situation, the
transmission needs to be disassembled for inspection and repair.
### Chassis-related issues -
**Question**: What should I do if the vehicle drifts to one side while driving? -
**Answer**: First, check whether the tire pressures are consistent. If they are different, adjust them to the standard pressure.
Then check whether the front wheel alignment is accurate. If there is a deviation, a four-wheel alignment adjustment is needed.
You also need to check whether the chassis suspension components, such as tie rods and ball joints, are loose or damaged. If there
are any problems, replace them in time. -
**Question**: What's the matter with abnormal noise from the rear axle? -
**Answer**: It might be that the rear axle gears are severely worn, with the tooth surfaces flaking or deforming, and the rear
axle gears need to be replaced. It could also be a problem with the differential, such as damage to the planetary gears or wear of
the axle shaft gears. In this case, the differential needs to be disassembled for repair. It's also possible that the bearings are
damaged and need to be replaced.
### Braking system-related issues -
**Question**: What should I do if the braking distance is too long? -
**Answer**: Check the wear conditions of the brake pads and brake drums. If they are severely worn, replace them in time. Check
whether there is air leakage in the braking system. If there is, find the air leakage points and repair them. You also need to
check the brake fluid level and quality. If the level is too low, replenish it. If the quality has deteriorated, replace the brake
fluid. -
**Question**: How should I handle the situation when the ABS malfunction light comes on? -
**Answer**: It might be a problem with the wheel speed sensor, poor wiring connection, or a malfunction of the ABS control module.
First, check whether the wheel speed sensor is damaged or dirty. If so, clean or replace it. Then check whether the wiring is
loose or broken. If there are any problems, repair them in time. If both the sensor and the wiring are normal, it might be a
problem with the control module, and you need to take it to a professional maintenance shop for inspection and repair. ###
Electrical system-related issues -
**Question**: What could be the reasons for difficulty in starting or failure to start the vehicle? -
**Answer**: It might be that the battery power is insufficient. In this case, you need to check the battery and charge or replace
it. It could also be a problem with the starter, such as worn carbon brushes or a damaged solenoid switch. You'll need to repair
or replace the starter. You also need to check whether the wiring between the engine ECU and the starter is normal. If there is an
open or short circuit, repair it in time. -
**Question**: What should I do if the indicator lights on the instrument panel don't light up or display abnormally? -
**Answer**: Check whether the fuse for the instrument panel is blown. If it is, replace the fuse. Check whether the wiring
connections are good. If they are loose or broken, repair them. If both the fuse and the wiring are normal, it might be a problem
with the instrument panel itself, and you need to take it to a professional maintenance shop for inspection and repair or
replacement of the instrument panel.
