Calibrating electric steering (ESP)

[aaron92]

hello, i changed my steering colum and i need to calibrate the par sensor, but i dont know if i can do that with Multiecuscan, i have free version at this moment, and the section electric steering coloured in red... this isnt posible or it's just that i need registered version? Thanks in advance

PD: Doing it on Fiat panda '04

Module/Functions in Red on the Supported Vehicles list/page require a registered version of Fiat ECUScan.

Okay, thanks So i'm gonna purchase the registered software, just a last question...

- Can it access other ECUs for calibrating ASP( Absolute steering point ) of other vehicles that arent fiat/lancia/Alfa but does have the same electric steering system?

In case you dont know, do you know how to calibrate a hyundai accent MC '07 that got changed the full steering colum?

Thanks in advance!

Multiecuscan should connect to EOBD II compliant Engine ECUs. It will warn of invalid ISO code but you should be able to carry on and connect. However only base EOBDII parameters will be available.

It is very remotely possible that Multiecuscan can connect to other makes of non EOBDII modules if they are the same make/type of module used on a Fiat. Again invalid ISO code warnings will be given. However often although the same modules are used across makes of cars the manufacuturer specifies their own command / protocol.

I would NOT purchase Multiecuscan on the basis that it might be able to talk to other cars besides those listed in the official Supported Vehicles list.

Sorry I know nothing about Hyundai vehicles.

There's technically no such thing as EOBD II.
There was OBD-II which standardised engine management diagnostics for cars sold within North America from 1996 onwards.
The European equivalent is EOBD, which came in for cars sold within the EU from 2001 for petrol and 2004 for diesel (and a year earlier for newly introduced models)
</Pedant Mode>

Importantly though, EOBD and OBD-II are engine management diagnostic standards - they don't apply to other systems on the car.
It's very unlikely that a tool designed for one manufacturer would offer coverage for vehicles from another, unless those 2 manufacturers shared a platform for the vehicle (Citroen C1/Toyota Yaris etc).

FES is not likely to support any Hyundai systems.

Hi Juggers2k

OBD and OBD-II. Yes basically agree with you.

However EOBD does have an EOBD2 extension ('Enhanced On-Board Diagnostics, Second Generation').

I was trying to convey to a novice that ODB and EOBD are universal standards that manufacturers have to comply with for their basic engine management ECU emissions functions covered by the standards. This means that Multiecuscan will talk to ODB/EOBD compliant engine ECUs.

As you and I point out other systems control units will almost certainly be manufacturer specific.

But yes you raise a valid view and also how difficult it is to 'generally' address these technical details for the less technical.

Hi Juggers2k

OBD and OBD-II. Yes basically agree with you.

However EOBD does have an EOBD2 extension ('Enhanced On-Board Diagnostics, Second Generation').

That's a common misconception, as OBD-II is "On Board Diagnostics, Second Generation".
The same doesn't apply to EOBD though, which was introduced 5 years after OBD-II, and was already based around 2nd generation systems.

The emissions portion of the legislation has been tightened with the Euro 4 (2004) and Euro 5 (2008/9) emissions standards, and will be adjusted again with Euro 6 in 2014, but the diagnostic standards involved have remained the same (albeit with additional live data parameters being included in an update).

With regards to FES connecting to EOBD compliant ECUs, that doesn't seem to be the case. If I try connecting to a Vauxhall Corsa ECU that I know to use the KWP2000 protocol, using the settings for a petrol '03 Punto, it won't connect.
This doesn't entirely suprise me though - even EOBD compliant ECUs tend to have 2 ways to access the diagnostic system - on the EOBD protocols it will only display what is legally required under the EOBD regulations. Using the car manufacturer's own diagnostic protocols, you get deeper access to the same module.
On our test Vauxhall ECU for instance, EOBD finds 2 fault codes, while a package using Vauxhall's implementation of KWP2000 can get more than 10.

EOBD2 is not a new version of EOBD.
EOBD2 tends to refer to manufacturer-specific features available on some OBDII/EOBD tools to access additional parameters/information from a car, over and above the normal parameters and information available within the EOBD/OBDII standard. There are, as such, no 'EOBD2 cars', i.e. cars that require an EOBD2 tool to access their diagnostics information.

I did refer to OBD, ODBII, EOBD and EOBD2. Yes OBD, OBDII and EOBD are tightly defined/specified but manufacturers are adding "extras" into the base EOBD and this is refered to (very loosely) as EOBD2. As such EOBD2 is not a standard however if Mercedes add "function x" to their basic EOBD support then they have extended their base EOBD formal coverage. Fiat may add "function y" to their base EOBD support. Again and extension of base EOBD.

The likes of Sun, Autel, etc. diagnotic kit manufacturers often quote EOBD2 to indicate that they cover the base EOBD and some or all of the "extras" a given manufacturer has extended the legal EOBD by.

All very confusing and manufacturer specific.

This whole OBD/EOBD is going down the same growth pains as Wireless communication technology did in the IEE802.11 (N, N+, G, G+ and a host of other manufacturer specific variations on the base N and G specifications).

Anyway, we are basically reading from the same hymn sheet and hopefuly others will get a better insight into the OBD landscape.

Hello.. i purchase the license for 1year, but i have one question... it's about accesing Electronic steering...
what i got:
-Panda '03 1.2 8V
-ELM Interface
-Vag-com interface

I connect the ELM Interface, turn on the key, access multiecuscan but cant manage to get in electric steering menu... i'm getting an error that refers to the type of cable i think.. Something like "Connect the adapter 1/ Green (or 9 pin) ".. I'm in need of calibrating the ASP of the electric steering as soon as posible... so any help could be very helpful.. if it's a cable what's needed, if you can tell me where to buy it would be better... well.. thanks in advance

[aaron92]

Well, i investigated a bit, and it seems that i have to get a new adapter for the elm interface for accesing this module... so can i buy the adapter 1 at any web? or have i to make it myself? Thanks
