Need Some Help With ScanTool ELM 327.

**tata12001** · 11-16-2009, 05:38 PM

When I hook the scantool to my car DLC (OBD 2 ) , & I choose the right settings ex: Port number and Baud Rate. It shows that it is connected and ready to use, but when I try to read codes it shows that everything is N/A Although it is connected correltly.
I got a screenshot to the OBD information from About in the scan tool application
and as you can see the OBD system is N/A !!! Although it reads all other information especially the Protocol correctly.

The latest version of ELM327 is 1.3a. Yours is showing up as 1.5, which means you got ripped off (they sold you a dud).

I know it is chinese clone, but it could read my protocol & it shows that it is properly connected!!!!. BTW I tried ELM scantool ( this one http://www.scantool.net/scan-tools/elmscan-iso-usb.html ) a year ago but it made the same problem :S it shows that it is properly connected, but it could not read codes or sensor data.
My problem is when I choose About from that page ( http://www.scantool.net/catalog/prod...d/43/image/56/ ) and then choose OBD Information I got ( http://img4.imageshack.us/i/obdc.jpg/ ) so it could get my Protocol & the LED indications light on.
This is the scan tool which I mean ( http://www.made-in-china.com/image/2...LM-327-USB.jpg )

The point is, ELM327 v1.5 does not exist. The latest version from Elm Electronics is 1.3a. So your scan tool is not running legitimate firmware, and is probably faking a successful connection.

Your car is defective. You need a new car.

But seriously, there could be something wrong with the OBD-II port or cable if 2 different interfaces are showing the same problem. See if autozone or some place will check your car with theirs for free.

What year is the car?

By the way, which device reports 1.5a??

That little square one says 1.5a http://www.made-in-china.com/image/2...LM-327-USB.jpg

It's a reverse engineered one LOL It does work, but if it doesn't, well, try to get a refund I guess.

My car is 2006
And the device is http://www.made-in-china.com/image/2...LM-327-USB.jpg

It could read my protocol & the LED light on when it is connected, this is weird!!!

Should I restart after changing the port number ? or after installing the driver & software ?

BTW I did not buy it till now, but I just try it from a friend as I really need it. but the same problem appears as before

Really I need help

Try connecting with ignition in key off position. If the scan tool still detects the protocol, it's faking it.

Where was the car originally purchased?

I tried to connect it with ignition OFF & also ON !! ,but it refused to get any information , the car engine should be running to connect to the ECU & get the information.Is there some sort of protection on the ECU ?

The car was purchased from Kingdom of Saudi Arabia 2006 , it is gulf specs
