iCarsoft POR v2 Diagnostic Kit - User Experience.....

[jonttt]

I have extracted this from my 987 journal to also create a seperate thread as it may be useful to people who are not necessarily looking in the 987 section of the forum..........


iCarsoft POR v2 Diagnostic user experience.......

So I've had a problem with my UK spec 2011 987-2 Boxster S Black Edition ie the common window drop on door open failure.......its been sparodic and inconsitent in presentation and is more than likely down to a poor / failing solder in the drivers door locking mechanism........but it could be other control units involved in the process........this is something which cannot be diagnosed using a generic OBD2 connector ie generic OBD2 readers can only read generic input which is standard across all car makes (not just Porsche) ....when more specific control unit readings / diagnosis are required a car specific diagnostic machine is needed......

......So although the likely cause of the problem was known I decided to take the opportunity to buy a specialist diagnostic device for the car......

Some quick google research led to a few options but one consistant, modern, easy to use solution kept on popping up on the best / recommended buys.....the iCarSoft POR v2........this is designed to use on a wide range of Porsche models ie not just a 2011 Boxster.......so far as I can tell there are versions for various car makes eg mercedes, BMW etc....with the POR being the designated Porsche version......there is even a version that will do many makes of cars, which is not that more expensive and so may be a good option if you have a larger fleet of "out of warranty" cars (the iCarsoft CR v2 which I think does x10 different makes of car including Porsche).......

I purchased mine from ukpartsdirect using their eBay store for £136 delivered.....it took 3 days from order to arrive (even in virus pandemic restrictions) .......

I've decided to write this user experience as I simply could not find a lot of detail on this diagnostic device for the Porsche other than basic specs ie I was not even sure what control modules it can "see" / diagnose / error find / error clear / etc.......before ordering and the actual user manual when you do get it is very generic and not specific to the Porsche tests is actually capable of doing......

Hopefully others will find this of use......it is worth noting I'm not endorsing this unit in any way.....I have not used any other (other than a cheap bluetooth OBD2 generic reader)........and so I have nothing to compare it to / against for the more modern Porsches.....my only other experience of Porsche diagnostic devices is the original OPC Bosche "Hammer" I have for my 993, given that is c25 years old technology.....cost me >£1,000, is original Porsche diagnostic equipment and is like rocking horse poo to find ......its not really a fair comparison to an off the shelf relatively cheap device....

So what do you get......well you get a nice box.....

and in that you get a nice case......

and in that you get a nice quality / feel device and associated cables.....

the cables are:

- a serial to OBD2 connector cable (for in the car diagnosis)
- a USB to mini USB cable (for connection to a computer)

power is supplied to the unit either via the in car OBD2 port or computer USB cable ie it has no seperate power cable or battery requirements.

Next to the mini USB connector there is a micro card slot. This comes preinstalled with a 256MB card. I have not tested out what this card holds but the unit does have a facility to record test results which are written to this card......it may hold the actual dignosis software but I have not bothered to check that as I presume its either hidden or on programmable memory within the unit ie to avoid piracy ?

So the first thing the very generic manual tells you to do is to connect the device up to a computer via the included USB cable to update the software / firmware........to facilite this you do need to download and install some driver software from the iCarSoft website first so make sure you have admin rights to install software to whichever computer you are going to use.....

The software installed without any issues and when the devices USB is then plugged in it is recognised as a new drive by the computer. The installed software can then be ran to check for software / firmware updates....

mine actually showed that it had the lastest software already installed and so there was no actual need to update....

Now that the device is powered on whilst connected to a computer you are able to "play around" with it. This will however only allow you to do so much as to actually carry out any diagnosis or even see detailed sub menus of what modules can be tested for requires the device to actually be connected to the car....

so the main menu screen....

This shows options for (nb more detail on each later):

- Diagnosis (the main purpose of the machine)
- Service (this allows you to reset service lights etc....)
- Voltage (allows you to read battery voltages)
- OBD2 (this allows you to use the device on other makes of cars but only for generic / common OBD2 tests)
- Review (you can store test results for historical comparisons)
- DTC lookup (you can type in an error code to see the narrative if required)
- Setup (some basic setting such as imperial / metric units of measurement)
- Help
- About

The menu item you will use the most is the Diagnostic menu. When you press this it presents you with ......1 option ie Porsche.....I presume the x10 make model would present various options at this point ?

you are then asked to choose between 2 versions. I have no idea what difference there is between each as there was nothing obvious on some quick later trials save that a few messages are worded slightly differently. I simply chose what I presumed was the later v11.25...

This then takes you to a model selection screen(s)....

If you choose a model you are then asked if you want the machine to "smart scan" which modules it can connect to our you can choose a "manual" scan to see all possible modules for that model of car.....

To progress any further you obviously have to have the unit connected to the cars OBD2 port and not a computer !

So before I go into exmaples of my diagnosis of my 987's fault I thought it worthwhile summarising the different modules its possible to connect to for each model of Porsche it lists.....it is worth noting that later software versions may changes this list but this is as per my up to date software version as shown above.....

Using v11.25 of the Porsche Software installed choices:

Models selectable:
911 - 996, 997, 991
GT2 - 996
GT3 - 996
Boxster (presumably Cayman as well) - 986, 987, 981, 982 (ie 718)
Cayman
Carrera GT
Cayenne (9PA to 2010, 92A from 2011)
Macan
Panamera - 970

It is also worth noting that although you can see modules for each model of Porsche you cannot access the sub menus unless the car is connected. Therefore I can only detail the individual sub menus that are available for my car, a 987 boxster......

I will therefore start with the 987 Boxster as that is the most detailed information I have on the unit.......

DIAGNOSIS menu option.........

Boxster 987 (nb same for Cayman option without module 13)
* Manual Scans possible with the current software = 20 possible control modules
# Auto Scan of my car = 14 control units
ie 6 modules can't be connected to my car eg Tiptronic control as its a manual car.......

So for my car the unit cannot see TCM, TPM, DSM, WATCH, PASM, AWS.
My car does have PASM BUT I have the aftermarket DSC PASM controller fitted and so that is why it can't see that module.

The way the device works is that when you have chosen which control modules you want to see (ie Smart Scan or Manual) you can scroll through each .....eg here I have scrolled to the DDM (Drivers Door Module)....

The device checks it can communicate with the control module and if it can presents you with 4 options:

- Module information (this provides things like part number)
- Read Fault Code
- Clear Fault Code
- View Data

Eg Module Information for the DDM.....

if you then choose Read Fault Codes....

This fault was what I was looking for and help confirm that module is causing my window problems....

NB the problem with fault codes is that there is no "time stamp" on them so you do not know when they occured. It is possible for fault codes to be shown which have since been rectified or have been caused by other problems.....therefore the process should always be:

- check for fault codes
- clear any fault codes
- recheck for fault codes

That way you can be sure that the fault code is current and related to the current problem you are trying to diagnose.....

and so when I recheck for a fault code...

I can now wait for a problem and recheck for an error code


It is worth noting that I also found some other fault codes which seem to be related:

Vehicle Electrical System....

FECM (front end control module).....

RECM (Rear end control module)....

All helping to confirm there is a problem with with the DDM (Drivers Door Module)

All where cleared to be checked the next time I have a problem.


The last of the 4 initial module options "View Data" then allows you to go into the sub menus (listed above) to carry out specific tests eg...


if you want to check a switch is working eg the "Auto Air Con"...

Go into the AC module...

Choose the Auto button test...

It will show it as not activated....

If you now press the button.....

it will show it as activated as you press it....

nb this is NOT a test as to whether the air con is working but simply to test the auto button is.....if the climate will not go onto auto you therefore know its not a faulty button.....there are other tests for the actual air con system as per the menu system.

eg

So thats it for a 987 ie diagnosis with detailed sub menu checks that can be carried out......it is worth noting that you have to fault check each module seperately ie you cannot just press a button and it fault checks every control module it can connect to and report a list of faults.


So what about the other models of Porsche the unit can read. Well I can't see the sub menus without connecting to an actual car of that model but I can see the main control modules that it may be possible to connect to if the car has them..... so for each model......

Hopefully the above will help owners with other Porsche models have some idea of what control modules can be checked.

So what about the other device main menu options other than the main diagnosis....

SERVICE

Goes to a sub menu

VOLTAGE...

OBD2....

Allows you to read generic manufacture fault codes across other makes ie other than Porsche, as per any generic OBD2 reader...some exmaples (I did not photograph everything).....

REVIEW....

This is a nice feature as you have the option to save an error code to a test and review it later even after fault codes have been cleared.....it means you can compare test results over time...

DTC Lookup....

You can type in a code to get a narrative...

SETUP

So there you have it......I hope you have found this useful to understand what a 3rd party specialist diagnostic machine should be able to do and how it can help you understand / trace problems with your cars......

Good write-up.

Looks impressive for an after market bit of kit but sadly no good for OBDI equipped
993s.


Damn!

Ah.....you need the Bosche Hammer......I did a write up here.....

http://911uk.com/viewtopic.php?t=82158&postdays=0&postorder=asc&start=371

There is also a video of me actually using it to control the car somewhere in my journal .....

Good luck getting one though as I've not seen one advertised for about 5 years......they used to go for c£1,000 ....god knows how much they are worth now :grin:

 

[TV8]

This is a useful review. I bought one of these and have been pleased with it. I didn't connect it to a pc for an up-date or spot the review feature. Must remember to read the manual..

Lol, the manual is not very long :grin:
Re the review, you have to remember to save the error codes, it does not do it automatically :thumb:

 

[deMort]

I have to admit i'm pretty impressed with what it can do .. things like injector coding and DPF filter regen are very useful on the Cayenne/Macan diesels.

If you can find any coding options for the various control units then that would be the icing on the cake to be honest !

Excellent write up, I might consider one of these as an alternative to Durametric. Better form factor too.

DME diagnostic

Hi all,

This is my first post in this forum. My car is a 2010 Cayman S 3.4 PDK.
Two weeks ago I bought iCarsoft POR II because I want to diagnose an intermittent problem with the engine (PSM Failure). I guess iCarsoft POR II may have same capabilities like iCarsoft POR V2.
The POR II comes with latest software. I found out that POR II can not access DME menu, always got message " Fault in communication with vehicle ECU......." , but I can acces PSM, Tiptronic menus (Read DTC, Clear DTC, Live Data). In car selection menu I chose CAYMAN, also tried BOXSTER (987) but still can't access DME menu.
Any advise ?

 

[jonttt]

My understanding even though the POR II is the older unit to the POR v2 the added features only really relate to newer cars eg battery coding, Diesel DPF regents, etc.....so even though the POR v2 software is 'slicker" the II should be able to do the same diagnosis on a 987.2.........

....you mention that you can read other modules........mine read 15 of 20 (from memory) with the ones it could not not being applicable to my car eg tiptronic/PDK........how many modules can you actually read ie is it all of the ones you would expect with the exception of the main DME ?

If so I would guess there is nothing wrong with your diagnostic tool which may point to a fault with the DME control module, hence your problems ?.......if you can't see other modules you would expect to be able to see then maybe a problem with the tool ?

 

[Adelphi]

Hi Jonttt,

I don't remember how many modules I can read using manual scan mode,
but there are 2 or 3 modules I can't read (including DME ).
When I tried auto scan mode, DME menu can't be found.
Basically I am not sure whether DME access is a standard feature in iCarsoft POR II.
I send emails to iCarsoft technical support and sales more than a week ago, no reply yet.

I agree with you that there is possibility with faulty DME module in my car
but logically I shouldn't be able to run my car with faulty DME module.

My iCarsoft POR II has Porsche software V11.30, there are 32 files in this software folder.
I want to try earlier software version but I I don't know how to get it.

I think the PorII is supposed to be able to read exactly the same modules by model as the V2

Anyway I need to identify the intermittent problem with my car.
I will bring my car to a Porsche specialist garage, if they could access DME
means there is an issue with my iCarsoft POR II. I will update the result.
BTW I send my 3rd email to iCarsoft and still no response.

yesterday I went to an indy garage who has PIWIS, they can access DME so it means there is no problem with the DME in my car.

In conclusion iCarsoft POR II does not have the capability to access DME in my Cayman S 987.2.
