Diagnosis of the first failure can be measured. Application of gauges and instruments in accordance with nationwide standards for automotive parts and varied parameters of the efficient measure of fault prognosis and debugging is an indispensable technique. Don’t overlook the use of launch x431.Measure the length of use to the meter stick, and the length of the measure, including diameter, hole and displacement measurement to use to micrometer, micrometers, plug, plug ruler, tape measure, and many others.; force and gravity measurements to use to measure power meter, and weighing units, etc.; stress and vacuum measurement use to gauge and vacuum table, etc.. Automotive measuring devices even have a wide range of measurement items, akin to use for the measurement of sound pressure sound stress level of dB values; for voltage measurement to the underlying value of such use.
For the steering system failure, use the instrument and the front wheel before the beam measured worth of the steering wheels and so forth before the beam; use the tire stress gauge tire stress measurement; point scale the amount accessible when obligatory the rotation of the steering wheel to the exact determine cause of the malfunction. For the engine failure, to measure the cylinder within the engine cylinder after the dissolution of the diameter, measured piston diameter, thickness and open house, and so forth., to establish the exact cause of the failure to restore the engine; is to repair to re-measurement of the cylinder tube diameter, and in accordance with the requirements of groups, matching the piston and piston rings so as to fix the engine.
Diagnosis of electronic control system failure, even more indispensable measure, corresponding to unstable or power of the decrease engine work, the suspected oil strain is insufficient, we should use the pressure gauge pressure measurement system; suspected electrical control system electronic control problems, essential to use digital multimeter measuring voltage and resistance; with frequency counter and oscilloscope measurements such as frequency and amplitude. Therefore a variety of measurement instruments and scales are upkeep personnel extension of eyes and fingers, only to accurately decide the correct measure, while the seat of your pants is just the floor, the measurement technique and instrumentation technique combining the use of more measurement gadgets must be extra correct analysis.
Can also be sub-take a look at for diagnosis of faults. lexia3 on fixing problems may be very effect. The so-referred to as sub-checking method is the automotive mechanics of the motor automobiles on the line, with the system piping and test the character of the fault line of labor, inspections might be in accordance with the system beginning from the ability supply system to the enforcement businesses along the route lookup is also out there after to pre-order search, you’ll find from the middle, relying on the expertise of the examiner. If suddenly from the implementing businesses to find a good course, or should return back to previous search.
For instance, and instructions for lighting system failure, the precept ought to be power on – change – fuse – Relay – wire – mild bulb line, front to again beginning to seek out that expertise can first examine the fuse, some folks would possibly first check mild bulbs, there is folks could first examine relay, when the entrance to again or ahead, finding out may occur in the course of the issue may be bad combination switch, there may be damaged wire somewhere.
The brake system failure, the precept on the brake pedal needs to be – vacuum boosters – brake grasp cylinder – Brake Lines – load sensing valve – brake pipe – wheel brakes so as to be checked. For expertise you can from the wheel brake or brake master cylinder began checking, and then verify the other part; but troublesome for the brake system failure, it should be after using measuring devices used to to test and measure. To find the reason for the malfunction.
The steering drive system failure, the precept on the steering wheel should be – Steering – Steering gear – steering wheel of the order of inspection. For convenience, you’ll be able to shift gears from somewhere open, easier to find out fault in the steering gear or transmission of the rear part. Use of the existing theoretical data, with the sub-check for orderly conduct of inspection, will eventually find the foundation causes of failure.
Partial disassembly methodology may also diagnose faults..Known as partial disassembly technique, that’s, car mechanics Yijing identify a fault within the assembly Mouge After it, a time not Zhunquepanduan which half of the failures occurred, they will in accordance with the meeting of the working principle of the demolition of a local Bufen function examine, and then put one thing in the tactic. If the method used correctly, can instantly determine the site of fault, due to this fact, be thought to be a easy partial disassembly method of rapid analysis of vehicle faults.Partial disassembly technique and test method has many similarities, the difference is mainly local demolition methodology to demolition, dismantling and check out again in a diagnostic faults.
For instance, a suspected engine cylinder will not be working, single-cylinder off oil removing method can be used to check, remove the partial demolition of a high strain pipe fittings cylinder engine operating in both pace and sound change is that the tank is working correctly; with out reflecting just isn’t working correctly.A few of the most effective main to diagnostic strategies, akin to mb star.Lack of engine power when the suspect blocked air filter, you’ll be able to attempt removing the air filter core engine, corresponding to the power of the air filter case without recovery, fault right here.
Partial disassembly methodology is definitely to work the engine or the electric lack of the unique function, while movements in non-normal conditions, it must watch out disassembly, in relation to security initiatives to take acceptable safety measures. Better expertise has launch x431, lexia3, mb star. All the fault analysis methods are complementary, the purpose is to find the automotive the fault occurred. Flexible use of fault analysis, fault can discover cars, targeted on the cars and engines upkeep, restoration of regular use function.
