BMW scanner 1.4 won't find dme

Ok so I recently bought a BMW scanner 1.4 for my 2001 330ci because my check engine light came on and I thought it would be cool to have. Well anyway I finally get the right drivers installed. Thanks to windows vista that was a pain. I scan everything plenty of errors found. Actually found out my vehicle has been crashed. But the DME is not found. The only thing I really but the scanner for was to access the DME. So I followed some forums and soldered pins 1&2 and 7&8 together, and guess what? It still can't find DME. Has anyone else had this problem had fixed it?

Not really a solution to your problem, but if you have a check engine light then PA Soft won't help much. You'd be better off with a Bluetooth OBDII interface and a smartphone app.

BMW scanner 1.4 won't find dme

This is not a response to the OPs question, but. To post #2 above. The OBDII reader will only read the generic fault codes. Using PA Soft you will get the BMW specific fault codes. The BMW codes can give you more information than OBDII codes.

Regarding not being able to read the DME, that's not right. I forget how it's wired. I think PA Soft talks to the instrument cluster and which acts as a router and directs traffic to the k-bus or to the d-bus for the DME.


I just looked it up and the D-bus goes directly from the DME to pin 8 on the diagnostic connector. You should be able to talk to the DME even if the cluster was not there.

Any OBDII device can read the codes that trigger a check engine light and IMO are more useful than PA soft in solving the problem. PA soft is more suited for the SRS system, the LCM, the IKE, and other non-OBD compliant modules. For drivability issues, an ELM327 and a smartphone app is the way to go.

Scott, not directed specifically at you, but this same misunderstanding and wrong info is perpetuated time and time and time again.

Sorry, I MUST clear up this total lack of understanding on OBDII and what tools are best for drivability and what tools to use when the SES/CEL/MIL comes on. There is some "myth/mis-understanding" that is regularly perpetuated on the Internet that generic OBDII tools are not useful and a waste of money, this is TOTALLY WRONG.

AndreBXP is one of the few Fanatics that "gets it" and understands that BMW Scanner 1.4.0, INPA and other BMW specific tools are NOT the best for basic troubleshooting and gathering data. Additionally smart phone/tablet Apps and wireless interfaces are far easier to set up, use and the smart phone/tablet Apps have FAR more power than any of the BMW specific tools. Most of the BMW specific tools were written over 15 years ago, for older, slower computers and the user interface is typically archaic as compared to what is being released on Apps today.

Here is the short version.

IF the SES/CEL/MIL lights up on the dash, ANY generic OBDII tool will be able to read, display and clear ANY code(s) that triggered the SES/CEL/MIL on ANY make or model vehicle, BMW, Ford, GM, Mercedes, Honda, Tesla, you name it. Manufacturer tools can typically read both OBDII codes that light the SES/CEL/MIL, HOWEVER, they can also read the long list of codes that DO NOT light the SES/CEL/MIL. However, for drivability issues, the SES/CEL/MIL will be lit for most errors and manufacturer tools typically do not offer a significant amount of additional information. Any additional info the manufacturer tool may offer is typically not going to be a silver bullet that leads to a 100% diagnosis and tell you to replace part X for cylinder Y. It may provide a bit more information to "confirm" an original diagnosis, but it generally will not be an earth shattering sliver of the puzzle that was required to solve a problem.

Generic OBDII tools can read generic OBDII codes as well as Manufacturer Specific codes as long as they follow the OBDII protocol and and PID format. OBDII has provisions for "Manufacturer Specific" codes, this is nothing new and has been this way for close to 20 years.

There is a 3rd layer or type of codes that I refer to as "Manufacturer Specialized" codes. These "Manufacturer Specialized" DO NOT light the SES/CEL/MIL on the dash, matter of fact they typically do not alert the driver in any way or form. They are typically not read by "generic OBDII" tools, but they can often be read by more expensive "Pro Tools". So for example higher end SnapOn, Autel, Launch and other tools can typically read and display "Manufacturer Specialized" codes. But usually the threshold for tools that can read the "Manufacturer Specialized" are around $400+, usually the more money, the better the manufacturer coverage and the more in depth these tools cover.

So for example, many of the tools that support "Manufacturer Specialized" codes are PC based, not very easy to install, require a computer to be used in/at the car, often have foreign languages to deal with and/or have language translation errors or misleading descriptions. Asian versions of BMW Scanner 1.4.0 specifically often have issues where the interface needs to be taken apart and pins inside the dongle need to be soldered! Additionally, most of these software based tools have limited Live/Realtime DME/ECU information, slow update/refresh rates and often cannot Log the data stream. BMW Scanner 1.4.0 does not have full Live/Realtime data on all year and DME versions.

What these tools do, is often give slightly more insight to the errors and often give so many errors that someone new to these tools starts chasing their tail looking for "non-problems". For example if you scan a car with BMW Scanner 1.4.0 for the first time, you might find 20-30 errors. Many of these "errors" are really non issues. They may have been triggered due to a discharged battery or some fault that occurred long ago, was repaired and the code(s) were never cleared.

So a bit of care and reasoning needs to be applied when using a more advanced tool that may bring up "transient or older" errors.

I am not saying BMW Scanner 1.4.0, INPA or other BMW specific software is not useful, helpful or should not be purchased, but be wise, start with an OBDII smart phone/tablet App, learn how to use these and it will be your best friend. You will leave the $15-$20 interface in your car or cars and you will ALWAYS have an OBDII tool on you if you have your phone and interface. If the SES/CEL/MIL turns on, any decent OBDII scan tool will be your best friend and the best tool to start with. These tools will give more than enough information to identify and repair any problem that triggers the SES/CEL/MIL.

And to also be VERY clear, problems with other systems/modules in the car other than the DME(ECU) and EGS (TCU/Transmission Control Unit), WILL NOT trigger the SES/CEL/MIL. Other modules may trigger Brake/DSC/EML or other lights, but these system will need a more specialized tool or a higher end OBDII tool to read and interrogate the codes and data. Higher end Pro tools and manufacturer specific software or handheld tools will be required for this purpose.

Well no one really answered my question. But thank you for the information regarding the use of scanners I figured out the problem, the 7 and 8 pins were not soldered well enough. re soldering solved the problem. I found the code setting off the check engine light. Turns out it was just a lose gas cap Thank you again for the replies! I am very thankful for the continues education I receive from everyone on these forums. I appreciate it all

I had to solder those pins aswell to get the thing to read more than two modules. I managed to replace airbag and get rid of airbag light with bmw scanner 1.4.

This is interesting! Mine doesn't read the DME as well. I opened the interface module and find no wire going to pin 7, but pin 8 has two wires soldered to it. In addition, pin 4 and pin 5 have been soldered together with one wire. There's a wire going to pin 1 and pin 16 and one wire is cut short not connecting to any pin. I have BMW Scanner 1.4.0. What wires do I have to connect to what pin to be able to read the DME? Thanks.

I soldered 7 and 8 together along with 1 and 2 tried it and it didn't work. So I took it apart and resoldered 7 and 8 and boom all worked.

Does yours look like mine with one wire cut short and two wires soldered to pin 8?

That's exactly what finally made mine work.
If it's not a good solder, it reads many other pages, but not the DME.
Mine works every time now and you can clear the codes and make the CEL/SES light go off. But it will come back if the problem is not fixed.

My solder joints look good but don't have a connection to pin 7. Before I fry something, I opened a ticket with http://www.resettools.com/bmw_scanner_1.4.0 where I bought that thing. They clearly show on their website that this will support some of the "unlocked" functions. Btw, the EGS is not working either.

Update:
Five days have passed and no response. This is what their response was to my ticket; "Your support ticket "BMW Scanner 1.4.0" has been submitted. We try to reply to all tickets as soon as possible, usually within 24 hours."

After reading this thread http://www.bimmerforums.com/forum/sh...de-car-options, updating the software and drivers and matching up a scanner configuration with mine, I soldered pin 7 and 8 together. Voila, DME and EGS can be read now. It still amazes me all the different circuit boards and wiring schemes on the hacked versions.

PA Soft lowered their price to $650.00 which could be well worth the money if you keep owning E46s. BTW, it has been confirmed in the upper link that this software also works on some Range Rover models.

Something to watch out for with older models

Something I've found using Pa Soft 1.4/BMWscanner 1.4 on an older model, a 96 E38, if you you get the issue with PA Soft not seeing all modules, check the diagnostic socket for corrosion. It doesn't take much to limit the voltage going down the K lines which can result in certain modules being "invisible". I had this problem on mine and it took me two weeks of messing around to discover the cause! The corrosion looked minimal but it was enough. I sprayed WD40 into the holes then spun a small torx screwdriver inside each hole - small enough not to enlarge the holes - to grind off the corrosion. I then put the round 20 in plug into the socket and wirked it up and down a few times just to make sure it was making good contact on all pins. Once I'd done this, I plugged in my laptop and suddenly the DME, GS and ABS modues were visible. All three were "not found" before.
