Seek Reliable Diagnostic Tool for Honda CR-V

My brother recently tried to find for his 2012 Honda CR-V a well-performed auto diagnostic tool. He is very familiar with auto parts and some basic repair knowledge, while has no idea about how to choose a tool which does benefit his car to the most.

Exactly, I cannot give any good recommendation. So I turned to ask engineer for help, once helped solve my problem patiently and successfully. And my e-mail was got immediate reply, which is shown below together with my coming letter.

Hello Joy,

I write to you aimed to find a really useful and compatible auto diagnostic tool for my brother’s 2012 Honda CR-V. According to his requirements, I concluded all the highlights as follows:

1. The device must contain main basic diagnostic functions; it had better do some ECU programming.
2. It needs to be compatible with wide range of car models. Although it will, at present, be mainly used for his car, I do not it only supports few models, especially support most of the Asian car models.
3. It had better equip with WIFI function, it is, at least, allowed to use USB cable for connection.
4. Update can be easily operated via internet.
5. No activation or registration before using.


Dear Mike,

I have already caught your main ideas from the coming e-mail. Here I would like to recommend you VDM UCANDAS. Exactly, this tool has recently been updated to the newest V3.8, which add it more new feature to support diagnostic work.


The multi-language VDM UCANDAS is a wireless auto diagnostic tool with powerful function, such as read and erase DTCs, datastream, actuations, ECU initial startup and more. For car models, it covers 47 car brands, which popularizes Europe, Asia, Australia, USA and China.

And now you only need to pay €210.00 to get it home, it is worth buying for car maintenance.

Best regards,

Diagnostic Procedure Astra via OPCOM 2010

I put the tutorial that I made during a repair of my Astra.

I also put at the end of a link to the screenshots on page outside the forum. I do not put directly on the topic, because there are nearly 200 images …

Note that I am presenting Opcom 2010. I am not the author of all the tutorials associated with the list of possibilities listed below.


What is OPCOM?

This is an interface that enables communication between a computer and the car.
It does not do anything that makes a Tech2 (pro device used in the garage) such as programming / update the computers, but it allows the modification and / or addition of unsupported options when buying .dropoff window
It simply allows also make the diagnosis.

What can we say?

-Screen CID color
-autoradio CD30 + DVD90 to CID
-Bluetooth UHP4
-computer edge
-Orders driving
Automatic -air conditioning


We can test for example:
-The Battery (voltage)
-The EGR valve
-The Fuel rail
-The Fans in front of the radiator
-The Lights bulbs, LEDs onboard instruments
-Know Wear oil
-Réparer The actuator of easytronic box and reset it
– …dropoff Window

It looks like this:
The price is about € 20.
If it looks like the photo, it’s good.
As for the firmware, even if it is not the last, it does not matter, the software will update!

The software:
OPCOM comes with a small CD on which the software. Direction trash … for me, it contained a virus …
The latest software version I have is the 100219a available by PM.
This is a newer but I’ve never used.

They are included with the software in the “drivers” directory. OPCOM running xp and seven 32 and 64-bit and win8.
Under seven (and win8), it may be that the computer refuses to install the driver because it is not signed. To overcome this, simply disable checks for drivers signatures. To do this simply, when starting the pc, maintain F8, and then select the line that disables checking.
I did a web page that details what a lot we can do with the software.
I will update as and when I use OPCOM.
For cons, I do not have all the options and existing engines or transmissions, so it is not complete … but it helps to get an idea.
