Steering mechanism includes a steering wheel (like the driver's seat airbag assembly) as well as the steering shaft. Steering linkage pitman arm, steering rod, shock absorbers and steering knuckle arm. The steering gear rack and pinion energy steering, steering pump rotor type.

Basic failure vas 5054a in the failure on the power steering program, steering noise and oil leakage. The basic failures contain tough steering, steering shocks, steering not functioning and steering kickback. A few of these faults may possibly be connected to energy steering, steering controls and steering linkage are associated. Brought on by the failure from the following describes the power steering device adverse, please refer for the basic failure with the vehicle steering mechanism with steering failure caused by the transmission mechanism analysis.

Initially, the general failure
(A) difficult steering
1. Failure phenomenon: Driving turn, turn the steering wheel really feel heavy effortlessly. Checking the rotational force with the steering wheel, and its value is greater than 30N.

2. Failure Evaluation
(1) Verify the oil tank is in oil, power steering pump drive belt is slipping, must confirm that no air within the program.

(2) Verify fgtech, fgtech galletto 2-master the energy steering pump pressure. Measuring the idle static hydraulic pressure manage valve and shut-off valve is totally open, the oil stress value ought to be equal to or slightly much less than 1500 kPa, otherwise it should be checked into the oil amongst the power steering and energy steering pump and return line The hose is clogged, aging or deformation. When the tubing is regular, then the steering gear rotary valve failure.

(3) when the measured energy steering pump stress is standard, within the case of your pressure manage valve and also the shutoff valve is totally closed, the measurement when idling pump unloading pressure, and its worth should be 7200 ~ 7800kPa. Unloading pressure is also low, you'll want to verify the flow manage valve and oil pump assembly.

(4) When the above checks unloading stress is typical, verify the rotation of the steering wheel towards the left and to the appropriate in the turning force, the difference in between the two need to be

Engine won't start and the way to complete?

We really should first auto diagnostic tool check out whether the distributor, spark plugs, electrical power lines, and so on. since the vehicle rain and also other moisture. In case the damp parts to dry, and after that launched. Directly or make use of the hair dryer blowing wet parts.

Second, check the spark plug for injury. If damaged, exchange the spark plug is usually so long as. Usually, automotive spark plug mileage of about twenty,000 to thirty,000 kilometers.

Test the battery voltage is adequate. The numerous batteries designed to the detection of the observation hole green when normal use, a black, must add factors, or maintenance, a white battery replaced.

Parking fail to remember to turn off the lights, it's possible you'll run from electrical power. If so, twist the ignition switch while in the ON position, the vehicle is linked for the second gear, foot clutch drag auto when traveling to a particular velocity, release the clutch, the car or truck are going to be capable to naturally start out. This strategy applies to only the electrical power failure, if your ignition program challenges, this technique not simply isn't going to function, may perhaps also possess a lousy result on catalytic converters, the auto also will harm the timing belt, result in major mechanical failure. Installing automated transmission car or truck, can't the carts get started, readily available jumper cables to connect the battery to start the engine with the other auto.

Edit this paragraph 5 maintenance underhand
1, oil plus sugar
Sugar entering the engine can be heated into fgtech a paste which can lead to the engine to 'hold tile', will not be functioning properly. The owners observed wrong car once more returned for fix, the owner can seize the opportunity with enthusiasm Henzai a.

2, gearbox oil plus brine
Gearbox oil brine into Riga, the gearbox will produce paste piece gearbox dress in, can accelerate the auto in about half the time, ranging from back to exchange the gearbox chip, substitute gearbox.

3, Brake oil plus alcohol
Brake fluid against alcohol, you are able to pace up the brake method dress in, "buddy" to open automotive plant owners will return following a few days there to exchange the entire brake components.

4, antifreeze salt vas 5054a
The extra salt antifreeze in to the engine tank, not only will develop scale tank, the circulating water flow, but also significant corrosion tank, triggering the tank harm. The owners head to replace the tank, "buddy" will warm reception.

5, the cleaning solution was extra caustic soda
Engine cleaning fluid to the Riga caustic soda, will accelerate the aging on the plastic pad, will induce a series of complications, "buddy" tea back to you "a good soak, seasoned servicing workers to find out the owners back time even the bad cannot 1 day

Diagnostic fault observation

The so-called obd2 code reader observation is the auto mechanic carefully observed the car users pointed out the location of fault fault phenomena, and then judge the fault, which is an application up to the most basic and most effective method of fault diagnosis. Such as hair dryer exhaust pipe to take the blue smoke of failure, to judge the phenomenon can take the blue smoke, such as in the course of long-term risk Lanyan really long mileage engines use generally can be judged as a cylinder or piston ring wear , resulting with the gap is too large obd2 scan tool, due to the oil pan of oil fleeing into the combustion chamber through the clearance between the piston ring and cylinder wall; future risk Lanyan if only emits blue smoke when the engine just a launch gradually become more mild and generally can be to judge the rod block oil engine valve cover aging or bore wear to block oil disabled, but a small amount of oil leaking into the cylinder along the valve stem caused obd2 scanner.

The experience can accurately judge, the inexperienced should further observation. In the observation process, but also with the experience and theory, make careful thinking and push the card can not be simply sloppy, can not be fooled by appearances. Some phenomenon for those with experience is not suddenly be able to see clearly, then they would have to look at a few times, careful observation, to the outside to the inside, to see through obd2 bluetooth the fault phenomenon.

Volkswagen Jetta cannot boot failure

Designs, car obd2 tools assemble the two-valve the BJG engine of a 2007 Volkswagen Jetta sedan.

Owners: get started vain motor vehicle just after automobile typical flame, turn around the ignition switch on the dashboard EPC lamp is not really lit, the decoder can not communication using the engine system.

Figure 1-22 is Digiprog 3 Odometer Programmer with Complete Application V4.82 a schematic of your engine handle unit powered Jetta sedan of 2007. In accordance on the schematic evaluation suspected J458 relay line failure. The J458 relay inner ideas and pin functions as proven in Figure 1-23.

Take out the driver side guard from your central power distribution box above to uncover J458 relays measure the relay to unplug the pin voltage, the actual measurement success present that only D foot 12V voltage, other the pin voltage are 0V. In accordance on the evaluation on the circuit diagram, the 3 Qiu feet need to possess a frequent voltage of 12V, this pin voltage fuse S51 more than likely blown. Immediately after checking the fuse S51 genuinely blown, examine the ignition coil fuse the management and engine management unit provide line and located no signs of the brief circuit, it can be estimated the last maintenance workers blown fuse short circuit check substitute the fuse, the dashboard EPC light still won't light, indicating the engine manage unit power provide isn't normal. The J458 relay pin voltage is measured again gets to be as follows: 11. 4V 85 feet, 86 feet 0V 30 feet 12 2V 87 feet 2.35V9 D foot twelve.18V. In accordance for the evaluation of the circuit diagram, the relay coil beneficial by way of the ignition switch management, damaging direct grounding speak to output of 87 feet voltage should really be 12V relay this motor vehicle 87 feet ahead of 2. 35V voltage fault is quite obvious, J458 relay contact failure, the substitute of the new relay, turn the ignition switch over the dashboard EPC lights lit, but the engine is still not the automobile. To communicate with all the decoder, several fault codes are mixture facets, simply because this automobile is usually a taxi, alteration of natural gasoline, dependant on previous experience that such models prevalent mixture fault code , irrelevant that vain motor vehicle failure, may be ignored, so the fault codes stored, clear fault codes, get started the car again and check the high-pressure fire, identified that high-pressure fire appropriately, then the the drive component check function in the decoder driven oil pump, you could hear the sound on the the J167 relay as well as the oil pump petrol tank, the essential pump get the job done typical. In this case, the go through fault codes, the normal show process. Just after 3 beginning the engine the automobile, it can be estimated the final servicing course of action, spark plug gasoline "drowned" forward on the auto following a few minutes, clear away from heat, then begin again, the car's engine is smooth, check, and found no other signs, recognized this automobile troubleshooting. Process frequently YANHUA Digiprog III exclude electronically managed engine touching the car or truck failed to verify the power of your engine control unit, faster approach is to check the dashboard engine fault light is lit within the dashboard of the automobile mentioned the 2007 VW Jetta EPC light in the engine management unit on the power-on LED, it can decide whether the engine control unit electrical power supply is ordinary. If your power provide is standard, to communicate with the decoder, to see no matter whether the fault strategies, then the fault tricks to a stage by phase troubleshooting. Motor vehicle failure will not be challenging, however the method of elimination plus the correct flow detection, to be able to swiftly locate the the J458 relay contacts bad get in touch with level of failure.

DEUTZ diesel engine fault lights

Dump Trucks (the engine model BF6M 1013-28E3) car diagnosis tool a mileage of about 10,000 km, engine fault lights lit.

Troubleshooting 2: Reading fault code is a P0008, meaning the Backup mode is active; another is P0335, meaning the crankshaft position sensor signal. The engine can start, fault code can be cleared, but Car OBD2 Tools after starting the engine running for some time, the engine failure light up again. Clear fault codes, engine place to start, and engine fault lamp is not lit, the vehicle running for some time, failure to appear, failure may be the harness or wire connector poor contact, or harness damage at. After examination, the fan grinding off the engine wiring harness (transition harness) caused failure. Damaged harness, obd2 software and troubleshooting.
