What problems can OBD2 Scanner Detect

5

OBD vs. OBD2

ODB scanner is an abbreviation for On Board Diagnostics Scanner. An OBD2 Scanner can read trouble codes that trigger the check engine light. OBD2 scanner tools are the latest industry standard and is incredibly more versatile than its predecessor. In 1988 the Society of Automotive Engineers (SAE) set a universal connector plug and a universal set of test signals / trouble codes. Unlike a basic scanner, the OBD2 scanner has a greater ability to define trouble codes and provide more accurate diagnosis, along with being able to tune or tweak performance. In 1996 the OBD2 scanner was implemented and became the industry standard.
ODB2 Scanner Basics

An car Repair Software can detect many things that are going on with your vehicle. It read trouble codes produced by your vehicles onboard computer system. The on board computer system monitors your cars emissions, performance, and numerous other functions. Those codes with trigger and illuminate the check engine light; letting the owner know something is wrong and needs to checked out. The codes produced are 5 characters long. Below is the break down of what each character or digit represents.

First character represents the system related to the problem.

B = Body
C = Chassis
P = Powertrain
U = Undefined

The second digit lets you know whether the code is generic or enhanced

0 meaning generic
1 meaning enhanced

The third digit identifies the sub system that the code pertains to.

1 = Emission Management (air or fuel)
2 = Injector Circuit (air or fuel)
3 = Misfire or Ignition
4 = Emission Control
5 = Idle Control & Vehicle Speed
6 = Output Circuit & Computer
7 = Transmission
8 = Transmission
9 = SAE Reserved
0 = SAE Reserved

The forth and fifth digits are variable and related to precise problems.
Example of a Trouble Code

We will use the code P0171 as an example. This code in particular means “System Too Lean” (Bank 1). Possible explanations for this code vary and could mean one or more of the following.

The MAF (Mass Air Flow) Sensor is dirty or faulty
Note: There is an issue in some vehicles, the MAF sensors leak the silicone potting material used to encase the circuitry. Using “oiled” air filters may cause the MAF to become ineffective if the filter is over-saturated.
There could be a vacuum leak downstream of the MAF sensor
Low fuel pressure (dirty fuel filter/ possible plugged!)
Exhaust leak between the first oxygen sensor and engine
Possible cracked PCV line or vacuum /connection
Plugged or failed/ sticking fuel injector
Faulty or stuck open PCV valve Failed or faulty oxygen sensor (sensor 1, bank 1)

Professional Assistance Suggested

As you can see just having the code won’t do a whole lot if you aren’t familiar with auto repair. Car Diagnostic Scanner are very helping with diagnosing a variety of problems. It can also allow you to perform performance tuning. It is a great multi use tool that is imperative to any good auto repair shop. If you have any questions feel free to comment.

WiFi GM MDI Multi Interface GDS Tech2Win review

MDI GM (General Motors Multiple Diagnostic Interface) with WiFi is an interface between your vehicle DLC and a PC (by wired USB, wired Ethernet, wireless Ethernet ) and TIS2web.

GM MDI Scan Tool can certainly test all of the GM car from 1990 to 2013( Supports 2010-2012 Australia Holden).

Are available for SPS programming on current and also future SGM vehicles.
Required for diagnostics on new SGM Global A Electrical Architecture Vehicles.
Used with TIS2Web, GM Global Diagnostics System (GDS), SPS and MDI Manager Software.
Allows for GDS diagnostic.

GM MDI China clone Working well. Tested with GDS2 v.12.

Device works with GDS2 (Opel).
Device works with Tech2Win. (Opel, Hammer)
Device not works with SAAB via Tech2Win.

Price: USD259 + shipping cost(based on your country)

The MDI came ready to use with the software installed. It worked since I already had Tech2Win, GDS2 and GM MDI Manager installed on my laptop. It works extremely well and I have no problems with it. The product image at the time I order showed the cable keeper, A/C 12 volt adapter and multiple diagnostic interface user’s guide CD which is used to install the MDI manager software on your laptop. These items were not included. It also said it was Wifi but did not come with a wireless card but with a wireless interface instead. There are two versions of GM MDI Scan Tool on China market, cheaper MDI less than US$180 with only USB connection and the other more expensive with wifi wireless connection.

The product would work excellent if you had the MDI manager software already on your laptop.

7-4 7-5 7-6

My device tested with many cars for 4 months.
Device works with GDS2 (Opel).
Device works with Tech2Win. (Opel, Hammer)

Device not works with SAAB via Tech2Win.

Tested by my own, works with Saab 9-5, 2003, 3.0
It works with tis2000 and tech2win NAO.

My MDI clone from CnAutotool.com works fine with tech2win and also TIS2000 software. Used it for diags and pcm flashing with no problem (through usb port only, cause wifi is unstable for programming functions).

Added a wireless card to that one too, same flawless performance.. Only issue for me is that they all have the same serial number.. So using 2 of them in the same shop with wireless would be impossible..

compared boards from a genuine to this clone, almost identical.. multiple layer pcbs, same tracers, didn’t see any difference except the board labeling was missing on the clone.
Wifi GM mdi good, interface works online. update mdi 100%. offline not that good  for new cars.

Nissan consult iii Plus Ver.46.30 works on MDI interface as well (this is not tested by me, your are on your risk).
