How to make ELM327 work with J1850 PWM

I got myself an Elm327 V1.5 but I found that it will not work on J1850 VPW J1850 PWM protocol especial for most Fords. But it did work like a charm on cars.

My idea came from a post in mondeoklubpolska.pl/ forum. Thanks Atom from Poland. I got the post translated into English, then I tried it out on my 2001 MK3 duratec 1.8 and it works like a charm. So I make my new version.

I have to confirm that the method only fits for elm327 V1.5 as mine and I have no responsibility if your elm327 is blow up or broken.

Equipment needs:

Screw driver

Knife

Solder iron with very small bit and solder

Multimeter

About 10 mm of insulated small-gauge wire

Then do as follows:

1) Peel off the cover of the elm327 main unit and remove the four screws by using screw driver, take these out and set the box apart.

2) Check the elm327 inside is like this

3) You will notice that there is a PCB tack running between T5 and T2 there. Hook up a multimeter to check the continuity between the emitter of T5 and the emitter of T2 (on the side with two legs). If there is continuity, you should use the knife to cut between T2 and T5 as shown in red below.

4) Check between the emitters of T5 and T2 to make sure there is no continuity any more.

5) Solder a short length of wire between the emitter of T5 and the emitter of T1 or Pin1 of the output connector. Be carful not to apply too much heat to T5 and T1.

6) Again use the multimeter to test the continuity between T5 and Pin1 output connector. Ensure there is stable continuity.

7) Reassemble the elm327 main unit and try to test on J1850 PWM system.

 

The job is done.

 

Mini Viecar ELM327 scanner on Samsung Phone  

I got a mini Bluetooth elm327 OBD2 adapter for my Toyota Matrix 2005. I figured out that the tip is to get a mini version, in that case you can stock it in without having to loosen the bolts. Many software available for this mini scanner, but I decided to use it with Torque, because the great app is free. I have Torque installed on my Samsung NOTE 2. My mini Viecar adapter can be applied on Android and windows as well. But I prefer to hook it up to work via Bluetooth on my Phone.

I first connected the mini elm327 scan tool into the diagnostic socket, downloaded Torque software on Google Play Center and installed the free software to my phone. Searching Viecar2.0 Bluetooth after open Bluetooth setting. Than enter the pair code 0000.But my Samsung said “Paired but not connected”. I have to refer the user menu and figured out where the problem lies. Then I went into the configuration of Torque as follows: when you first open Torque, press the parameters icon, then press “Settings” and finally select“OBD2 Adapter Settings”, “Choose Bluetooth Type” and “Viecar V2.0”. I activated the “Faster communication” parameter and since then has worked well.

I suppose different elm327 adapters have different pair code. But in order to avoid my mistake, make sure do some basic setting (Choose connection type and Bluetooth connection device etc).

I have tried several cars, 2004 Toyota Caldina GT-Four, 2002 Toyota IST(also called 2005 Scion Xa), 2003 Nissan Sunny B15 etc. The Viecar adapter enabled me to get the fault codes from the plug successfully.I have tried both with the ignition on and the engine running. I have also tried disabling the elm327 automotive adjust and with try faster communication. Nice display parameters, cruse control, door remote etc. I gave the OBD2 scanner 5 stars because I feel $10 for the device is great deal. Just think about the price and you wont be disappointed.

Reveal Ford Focus hidden functions with ELM327 scanner

Recently, Ford Focus owners are getting excited because hidden functions of the vehicle are now accessible. However, since the original Ford IDS diagnositc cable, the tool to open these funcitons is so costly that car owners are hestitate to try.

Now, I would like to introduce my way to open these functions with $19.99 ELM327 scanner.

Step 1: Create a backup of the vehicle data in case anything goes wrong.

Step 2: Find OBD port, and conenct ELM327 with your car and your laptop.

Step 3: Turn on the ignition key and shift to the 2nd gear.

Step 4: Run the ELM327 software and start ROM upgrade. The ELM327 tool working light will blink. Wait for a few minutes later, the hidden functions will be available then.

Step 7: Enter dashboard setting and save the tire preseure.

Step 8: Long press the remote key and you will find that your sunroof can open and close automatically.

Step 9: Go for a trip and shift from the 1st gear to the 7th gear during the driving, and your car will be able to lock your vehilce from the inside. By now, you are finished.

I have opened functions such as overpeed warning, automatic lock, tire pressure monitoring, remote sunroof control and cruise control. A friend of mine who has installed xenon lamp can even adopts the tool to open xenon model, keeping his car computer from alarming because of the use of xenon lamp.
