How to diagnose and solve Auto Cylinder Leak

uobdii | 22 August, 2017 21:00

Cylinder leak detection using the cylinder leak detector.The basic principle of the test is to use the compressed air filled into the cylinder, with a pressure gauge to detect the piston at the end of the compression at the end of the cylinder when the Yanhua DR-Key adapter pressure changes, to characterize the entire cylinder group of OBD2 sealing.That is, not only the seal of the piston piston friction, but also to characterize the intake and exhaust valve, cylinder liner, cylinder head and cylinder seal.

 (1) cylinder leak detector structure and working principleDomestic QLY-1 type cylinder leak detection Diagspeed MB Key device mainly by the pressure reducing valve, intake pressure gauge, measuring table, calibration orifice, rubber hose, quick change pipe fittings and inflatable mouth and other components, as shown in Figure 2-12 The In addition, there must be an external air supply, a pointer to the piston position and a piston positioning plate.The pressure of the external air supply should be equivalent to the cylinder compression pressure, generally should be 600 ~ 900kPa. Compressed air according to the direction of the arrow into the cylinder leak detector, the pressure from the intake pressure gauge display.

WithAfter which it enters the cylinder at the end of the compression end through the pressure reducing valve Fcar FVCI Passthru tool the calibration orifice plate, the rubber hose, the quick change pipe fitting, and the inflatable nozzle. The pressure change in the cylinder is shown by the gauge. The pressure changesThe condition indicates the seal of the cylinder block.Cylinder Leakage Diagnostic Parameter StandardFor the cylinder leak, China has not developed a unified diagnostic parameters. Auto Repair

QLY-1 Cylinder Air Leakage Detector In the instruction manual, for the engine of the domestic truck, when the inlet, the exhaust valve and the cylinder liner are well sealed, the cylinder seal condition (mainly refers to the cylinder piston) Judgments can be dealt with in Table 2-6. When the meter reading is greater than 250kPa,Cylinder piston with sub-sealing conditions meet the requirements, the engine can continue to use; when the meter reading is less than 250kPa, the cylinder plug with the deputy seal does not meet the requirements of the engine cylinder to be ring or boring cylinder. Transportation industry standard JT / T201-1995 "vehicle maintenance process specifications" in the vehicle before the second maintenance of the use of the reference diagnostic parameters of the standard requirements of domestic Dongfeng EQ1090 and the liberation of CA1091 car cylinder leak, When the cylinder piston is placed in the static compression top dead center position, the measured gauge pressure should be ≥ 250kPa.

El-50448 GM TPMS relearn tool customers feedbacks

uobdii | 07 February, 2017 23:14

Here a collection of El-50448 GM TPMS relearn tool good feedbacks. Thanks to the real users’ contribution.



  1. works on truck and car: Simple and inexpensive but works great. Much better than going to the dealer or a tire store just to get your pressure sensors reset. I used it on my truck and my wife’s car and it only took a few minutes to reset all four wheels on each.

Well worth the money.

  1. with correct low battery display: I’ve never been able to get my TP sensors to program using the “let air out” method on my 2007 Tahoe. Before I had this tool, I would just remember which tires were which when I rotated them, but no longer. Now, I can reprogram them in just a few seconds and the dash display correctly indicates which tire is low. This tool should have come with the vehicle.
  1. Easy to use: The operation of this product is simple and straightforward. As stated it’s hard to get excited about spending this amount of money just to rotate tires, but considering what dealers would charge, it would not take many trips service visits to pay for the unit. As far as working it does exactly what it says it will do with no drama. Put the vehicle in reset mode and push the button on the unit following directions outlined in the car owners manual.
  1. I could not believe I needed a special tool to rotate my tires. From what I understand 2010 (2011?) and older vehicles, you can use any big magnet to reset your Tire Pressure Sensors. 2011 (2012?) and up to at least my 2013 Silverado, you need one of these gizmos. This one works like a champ, and is the one I found referenced through a GM website.

It is a simple process:
1) Put your key in the ignition, and turn it to run.
2) Press your lock and unlock buttons on your remote until the truck chirps. (There are a few other ways too, but this was easiest).
3) Start with the left front tire; the blinker light for that tire should light up to let you know which tire needs programming. Cool right?
4) Put this gizmo to the tire next to the stem, and press the button. After 3 seconds or so, the truck chirps
4) Then the front right blinker is on, and thats your next tire. Press the gizmo to the tire and press the button. Continue on to the rear right, and finish with the rear left. All the while following the blinker. Takes all of 3 minutes.
On one hand $50+ is a lot to ensure my tire pressure sensors are all aligned properly (I rarely look at them. On the other hand, I have a new tool and no strangers need to touch my truck.

  1. Wide GM vehicle coverage: The deflate method is verified ok only on Chevrolet Volt 2011 year, with the El-50448 TPMS relearn tool, I could get the 4 TPMS programmed in less than one minute. El-50448 could program TPMS on GM 2010-2013 year.

you can find the tool at any GM dealership, or buy it off online e.g I have a link here:

 El-50448 GM TPMS relearn tool price is 50usd by Paypal with delivery (15-20 working days) and pay more shipping fee; you could receive the package in 3-5 working days by DHL. PS: when you receive the package you can find it includes not charger and battery, if you need them, you need pay additional 10 usd.

How to choose Toyota diagnostic tool?

uobdii | 21 December, 2016 00:06

Tihs article is about Toyota Diagnostic Tool,we share top 3 hot diagnostics for Toyota.

1 Toyota MINI VCI cable
2 Denso Intelligent Tester IT2

The top 3 hot Toyota diagnostic interfaces is based on scientific analysis of many websites, including, obd365, eobdtool…

TOP 1 – mini vci Techstream cable ($26.99)


Cheap Xhorse-made knock-off
Popular Techstream 10.10.039 (tested by thousands of users)
– High reliability using SMD chip, and certified by CE and FCC
ALL communication protocols supported for Toyota (1996 – latest):
K-Line ISO 9141/KWP 2000 ISO 14230-4/SAE J1850 PWM/SAE J1850 VPW/CAN 2.0B ISO 11898 /CAN ISO 15765-4




The knock off cables use 1.4.1 or 1.4.6 (latest). The “real” cables use 2.0.1 or 2.0.4 (latest). They are all fake of course but the good fakes use the same firmware as the real Xhorse cable. The 1.4.1 firmware does not support active tests. The cable will work on 10 year old Toyotas like some in the GS forum have said but they will not work on the 2011 Prius as some on PriusChat have said.


TOP 2 – Intelligent Tester ITII ($285)


Newest version: 2016.7
– Multilanguage: English/ German/ French/ Spanish/ Italian/ Chinese
More accurate diagnosis through CAN communication for 16pin Toyota (1996 – 2010 better):
– Speed: 50 times faster than the conventional
– Easy operation: touch panel 5.7 inch full color LCE display



better hardware design than mini vci and Denso IT2
multi-system: WINDOWS XP and Windows 7/8/10
– multilanguage: Chinese, English, French, Italian, Spanish, German, ect.
WIFI wireless connection
12V and 24V communication
– model: diagnostic test for heavy truck and diesel models till 2016
– VCX is a standard Passthru programming tool, which can do online ECU programming

Mini vci cable is more suitable for the green hand to do basic diagnosis
Denso IT2 is ideal for technicians because of its high speed during operation
VXDIAG NANO for Toyota at a reasonable price, is the best choice for individual users and professional repairing men with better hardware design and powerful function (ECU diagnosis & programming, key programming).

Making choices of INPA, Carsoft, EDIABAS as BMW Diagnostic Tool

uobdii | 12 December, 2016 22:15

What is the software of choice for diagnosing BMW? I realize that people have different needs so here I will enumerate three bmw diagnostic tools to offer reference for you.

1st choice: BMW INPA K+CAN With FT232RQ Chip with Switch



  • $16.99
  • Works on BMW with 8 pin and with K-LINE protocol
  • Features: Read and delete errors, Adaptations, Driver programming, Applu coding, etc…
  • Supports Protocols:
  • Fast magisterial D-CAN and PT-CAN (500 kbit/s)
  • Slow magisterial K-CAN (100 kbit/s)
  • Standard BMW protocol (BMW OBD interface).
  • INPA is a diagnostic interpreter program that communicates with your car usingBMW’s own factory developed Electronic Diagnosis and Information protocol (EDIABAS). INPA is a powerful and comprehensive diagnostic tool but there is no simple handbook available that I know of which will comprehensively explain its operation or functions. The bottom line with INPA is if you do not understand what a particular function does, you are probably better off leaving that function alone, but having said that, the level of diagnostic functionality is truly exceptional.

2nd choice: BMW Carsoft 6.5 ECU programmer



  • $42.99
  • Features: Service interval reset, component activation, live data, LCM reading, sync. EWS and ECU, adaptation values, and coding.
  • Supports Vehicles:

E30, AB From 1998, E36, KOMBI Except kompakt, ZKE From 1994, ZVM Till 1994, E46, Z3, E34, KOMBI From 02/98, E39, E53-X5, E32

  • Carsoft is designed to allow home-mechanics to read and erase fault codes and reset service intervals. It has the capability to access most modules in your car including airbags, can display live engine data on post 1996 models and test components such as power windows and central locking.

3rd choice: BMW EDIABAS OBDII RS232 Interface



  • $29.99
  • EDIABAS can accomplish virtually any programming/diagnostic or coding function, but since it is only a computer protocol, requires seperate programs to interface between the user and EDIABAS so that it can receive and trasmit instructions. For example INPA communicates with EDIABAS to perform diagnostics, NCS to perform coding and NFS to perform programming functions. NCS and NFS are not particularly user-friendly and require fairly intimate knowledge of BMW systems to use. If used incorrectly, programs which communicate via EDIABAS have the potential to destroy computer modules, making replacement the only viable option.
