obd11

[merv m]

Do we still use the obd11 on our trucks? iwas watching U tube a while back and they mentioned something about using a DRB111 i looked it up 500.00 thats a pricey tool for the home garage------

OBD II is the Plug and the Standard - DRB III is Chryslers Workshop Tester - and plugs into the OBD Port of your Truck.

 

[Crunch]

I've considered getting a scan tool over the years, but have always put it off. Is there a recommended brand and model for the 3rd gen trucks that is also affordable?

 

[Ozymandias]

Check out Autoenginuity.com - it is not cheap but it is (probably) the most sophisticated Tool except from Snap-on or Chrysler.
Not cheap maybe but worth every penny.
I had some cheaper handheld tester but they dont work on every system, for example the antilockunit or they just don't know the Diesel.

For under $500 the AutoEnginuity works pretty well. You have access to just about all the PIDS, logging capabilities, test routines. etc.

DRBIII allows writing back to the ECU, you need a subscription to tech authority, and allows setting of all the BCM functions and features available. It also costs $2500-3000 to obtain.

OBDII is the older format. It was replaced in 2006 (IIRC) with the newer CanBus.

Just for grins, take a look at this http://www.scangauge.com/ I put one in my VW cause I wanted a engine coolant temp gauge, got a lot more than that. Even shows a calculated HP. More mileage stuff than you need and scans for codes. I cable to OBDII port to connect.

OBD is a set of information that is present thru the data port on a vehicle, it has nothing to do with protocols used to communicate on the data bus. OBDII or EODB is set of enhanced information a manufacturer could choose to provide on the data bus, not all did everything the same. All had to provide the standard OBD information but chose to provide more.

CAN and J19xx are protocols used to communicate on the data bus. CAN still provides OBD and OBDII information thru the data port. Most readers anymore support CAN and the proprietary protocols for different manufacturers so they can read a variety of makes and models. The cheaper models just don't provide as much data as the better ones. You also have to have the correct module for manufacturer to get the extended information because that varies from make to make how and what is presented. A lot of the info the AutoEnginuity presents is not OBD and Dodge specific with the Dodge module. You need a different module for the Ford or GM applications.

Get Kiwi Wifi and download the Dashcommand App, it resets codes as well, but has more than scan capability. If you want more info I'll download some pics for you, but it will have to wait for later. It's less than $200.00 and a 10 min install.

I also have AutoEnginuity too for the last 10 plus years, I also have the upgraded software for both Chrysler and VW. Its good stuff and easy to use.

Is it be able to read the ABS Codes?
Is it be able to do a Cylinder Contribution Test?
Is it be able to change Axle Ratio?

 

[RVTRKN]

Don't know, but I've never had an ABS code to know about it.

OBD = On-Board Diagnostic, a system to provide diagnostic information.
CAN = Control Area Network, a communication network between controller (ECM) and the other components that's directly unger it's control.

A controller area network (CAN bus) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer. It is a message-based protocol, designed originally for automotive applications, but is also used in many other contexts

From the OBDII specification.

Five Communications Protocols​

There are five protocols in use with the modern OBD-II interface, and often it ispossible to confirm the protocol in use based on which pins are present on the J1962 connector. One way to confirm is via manufacturer: The sure way is to remove and inspect the DLC using a wiring schematic.

ISO 9141 – ISO 14230 – ISO 15765​

ISO 9141-2. This protocol has a data rate of 10.4 kbaud, and is similar to RS-232.
ISO 9141-2 is primarily used in Chrysler, European, and Asian vehicles.
pin 7: K-line
pin 15: L-line (optional and referred to as “dual K” line)
UART signaling (though not RS-232 voltage levels)
K-line idles high
High voltage is Vbatt
Message length is restricted to 12 bytes, including CRC

ISO 14230 KWP2000 (Keyword Protocol 2000) used by most European and Asian manufacturers.
Alfa Romeo, Audi, BMW, Citroen, Fiat, Honda, Hyundai, Jaguar (X300, XK), Jeep since 2004, Kia, Land Rover, Mazda, Mercedes, Mitsubishi, Nissan, Peugeot, Renault, Saab, Skoda,Subaru, Toyota, Vauxhall, Volkswagen (VW) since 2001, Volvo to 2004
pin 7: K-line
pin 15: L-line (optional and referred to as “dual K” line)
Physical layer identical to ISO 9141-2
Data rate 1.2 to 10.4 kbaud
Message may contain up to 255 bytes in the data field

ISO 15765 CAN (250kbit/sec or 500kbit/sec)
pin 6: CAN High
pin 14: CAN Low

FORD Motor Company
SAE J1850 PWM (41.6 kbaud, Standard of the Ford Motor Company)
pin 2: Bus-
pin 10: Bus+
High voltage is +5V
Message length is restricted to 12 bytes, including CRC
Employs a multi-master arbitration scheme called "Carrier Sense Multiple Access with Non-Destructive Arbitration" (CSMA/NDA)

General Motors
SAE J1850 VPW (Variable Pulse Width) (10.4/41.6 kbaud, standard of
General Motors)
pin 2: Bus+
Bus idles low
High voltage is +7V
Decision point is +3.5V
Message length is restricted to 12 bytes, including CRC Employs CSMA/NDA

I read up on the autoenginuity Web site. The way I understand it is the basic system only reads engine parameters. It looks like you have to buy the enhanced software for a specific vehicle make. Which is not a big deal. Is this correct?
Also, does anyone have any experience with a matco md70 with fix advisor.

 

[Ozymandias]

Yes you are right, the Basic System reads the Basic and open OBD2 codes like any cheap code reader.
The Chrysler Enhancement opens the full world of hundreds of Chrysler specific values that no cheap reader gets.
The best way to tell if a software/scanner is good is when it enters the ABS System. Most don't.

 

[MGreer]

That's what I thought, so the basic system with the enhancement would be a good way to go for someone who doesn't use it daily. They have the basic system on their site for 250.00.

 

[cerberusiam]

They have the basic system on their site for 250.00.

That is the software only. Now you have to buy the particular vehicle module for about $240. That will get you the dongle that has to be available to connect to the vehicle. Total cost is about $490 for the software and 1 vehicle. That gives you access to everything they have in the Dodge module. Pretty extensive with what it reads and testing routines. You can do contribution percentages, injector kill, fuel system test, etc.

 

[Ozymandias]

I would say it is 99% of the DRB III - excel it can't write into the ECU except the Tire Size.
The rest is like the DRB but easier to handle.

If you are looking for something inexpensive for occasional use, search Amazon for ODB II scanners. I bought one like http://www.amazon.com/Panlong-Bluet...id=1434141319&sr=1-2&keywords=Bluetooth+ObdII.

Then download a free app to your phone and you are on the air! I use the Torque app.

Please recognize that this is pretty basic, but is useful for the ~$10 cost and occasional use. I use mainly on my wife's car. For my truck, I have all the functionality I need built into my Smarty! 8 )
