Are there any 1.4 StarJet/T-Jet owners out there with MultiECUScan? I have purchased a registered copy and now found that it can't connect to the Engine control module. Not sure if it's an issue with my ELM adaptor, or the ECU isn't supported.

I've contact MES support, will post back if I hear anything back

Hi,
Do you have the yellow adaptor? Can you read the CAN Info, read fault codes or connect to any other modules?

What interface did you buy? A link to seller would be good.

Yup, I've got the set of adaptors including the yellow one. I've successfully connected to the Body Computer Module and the Electric Steering Module, reading a fault code from the Body. I did have a quick look at CAN Info too, it seemed to read that fine.

The only ECM listed is "Bosch Motronic Me7.9.10 CF5/EOBD Injection (1.4 16V)", I'm thinking mine is another model that isn't supported. Perhaps an older or newer version

This is the interface, a modified ELM327: https://www.ebay.co.uk/itm/compatib...OBD2-interface-fits-Multiecuscan/281166266540

First off that interface should be fine.

Just to be sure, you are removing the yellow adaptor when trying to connect to the engine ECU?
From the first screen on MES click SCAN or Press F11 and see what modules are listed.

Yeah, I'm connecting the ELM adaptor directly (not via a coloured cable) when trying the 'Connect' button for Engine.

The Scan results:

Scan vehicle for available modules...

Engine / ECM
UNKNOWN/UNSUPPORTED
ISO Code: 7C 86 4C 85 A8

Body / BCM (Body Computer Module)
Body Computer Delphi (199)
ISO Code: 40 83 A2 04 3E

ABS / ABS/BSM (Brake System Module)
Bosch ABS 8 ESP
ISO Code: EC 07 01 83 4C

Electric Steering / EPS (Electric Steering Module)
Delphi Electric Steering

Interestingly, there are a couple of things listed by CAN Info:

List of configured control units :
Body Computer Node (BCM/NBC): Present
Engine Control Node (ECM/NCM): Present
Electric Steering Node (EPS/NGE): Present
Dashboard Node (IPC/NQS): Present

List of active control units :
Body Computer Node (BCM/NBC): Active
Engine Control Node (ECM/NCM): Active
Electric Steering Node (EPS/NGE): Active
Dashboard Node (IPC/NQS): Active

So it seems to be recognising there is something there for the ECM ?
 
Interesting. Are you having any issues with the car other than connecting to the engine ECU with MES?
Could be a connection issue or corrupted ECU. one other option is the ECU has been mapped and they changed the identification.

Two things to do next, wait for a response from MES or if you can't wait, have a look at the engine ECU and see what model number is on the label.

A connection issue isn't out of the question. The reason I'm trying to read fault codes for the engine is that I am trying to diagnose an intermittent battery/charging warning light - similar symptoms as described in this thread. I gave the earth connection to the ECU a clean anyway, just in case. Getting 14.1v between the battery positive terminal and ECU earth, so that seems fine. I think the battery light is more likely to be an issue with the non-Fiat alternator I have. Not getting any other weird electrical issues that might point to an ECU fault, and the car is otherwise running fine.

The ECU has a label with a few numbers, none of which look like Fiat part numbers. It does however say ME763.A0, and the ECU listed in MES for my car is Me7.9.10

Sussex..

Not too far from members on the forums MES register.. might be worth a try..

Just in case the 'latest version' has lost something with older tech cars..

Yes..I know you can load previous versions..
But using something established and functioning might seem a safer double.check

Im near oxford : newbury

Yes, very true. I'll try a Windows laptop of mine first, as I'm using VirtualBox on Mac to run MES, which could introduce some strange problem of its own. Although I would expect nothing to work if that were the case.

It seems the Bosch Me7.6.3 is listed as supported by MES for the Panda '06
1.4 16V, so I may try selecting that car and connecting that way. It probably won't work, otherwise MES would have picked it up when using SCAN. I will try out AlfaOBD too, to rule out an issue with MES compatibility.

I do actually get data showing up if I ignore the Invalid ISO Code error that MES throws when connecting. Some of it seems OK like speed (0mph) but some is definitely wrong like the Odometer reading and battery voltage (18.2v!?!)

If you can read the error code it would be a P0621 errorcode.
The non-Fiat alternator is probably the cause of this errorcode.
If you turn on ignititon and wait for 1 sec to start probably no battery warning light on ?
If you start directly you will get this light on (wait at least 20 seconds between starts)
With a universal OBD reader I think you can also read this faultcode.

If your alternator is compatible with this one OEM 51714794 you could try to solve the issue like I did.

OK, so I've tried a few different things today. In summary, I think this is an issue of compatibility with MES. My ELM connection seems to be functioning fine, although I do get a "Latency too high" error when performing the "Scan for interfaces" option in the settings. But anyway...

In MES, I tried the 'Bosch Motronic Me7.6.3' under the Fiat Panda '06 1.4 16V menu. I was hoping this would work as it's my ECU model number, but I got a "ELM327->OBD Connection Failed" error". Perhaps the Panda ECU is slightly different despite being the same model?

However, in AlfaOBD there is an option for 'Bosch Motronic MeD7.6.3' under Grande Punto and I was able to connect to this successfully! But, similar to my experience when using MES to connect to 'Me7.9.10', the odometer reading is incorrect (couple of thousand miles off), so maybe the other readings aren't quite right either.

In any case, there doesn't seem to be any fault codes stored so I've achieved what I need to. I've already purchased MES, but seems like AlfaOBD would be useful to have also if you have the StarJet (and presumably the T-Jet too). At least until a time when MES properly supports the ME7.6.3.

Yes, I can quite reliably replicate the problem by turning the ignition fully on very quickly. If there is a momentary pause between initially turning the ignition on and then starting, then there's no battery light and power steering works fine.

Strangely, I don't get any error codes (tried with my ELM interface and MES/AlfaOBD, and a generic OBD reader with Torque Lite). None are stored, and none are present even when the battery light is on.

It's strange that when I have this problem, the battery light is on, and the power steering is not functioning, but yet there is no PAS error light. It's impossible to turn the steering wheel, it's as heavy as when the car is turned completely off. It's as though the ECU thinks the PAS is working correctly, but it's actually shut down. There's 14.1v at the battery, and the CAN Info reports the same voltage too, so it's not a lack of voltage on the CAN bus...

I wonder what is missing from these remanufactured alternators that is present in an original Fiat part :confused:

As my problem is not only the battery light, but also the PAS turning off, I might check connections to the PAS motor...

Power steering faults probably won't be shown on the engine ECU you'd likely need to connect up to the power steering ECU to check it's status there

Ah yes, I should have made it clearer in my post that I have scanned all modules for codes, not just engine (y)

The 'battery voltage' listed as a parameter for the power steering ECU is normal, so it does seem to be getting power. :confused:

I think it does indeed receive power but is disabled by the battery monitoring module ...

The ignition module detects a D+ voltage below 5.5Volts when 700RPM is reached just after starting the engine.
See elearning documentation how to check D+ (alternator)

When this fault is detected, also the power steering module is disabled.
Even when battery voltages reaches 14Volts the fault can only be reset be switching off ignition.
When battery warning light is set for a few times the P0621 will be stored in the ECU and is shown as intermittent error and can be cleared.
The replacement alternator is slower in reaching the right voltage levels.
Switching on ignition and wait a second is enough to build up some magnetism in the rotor.

Putting a Capacitor in parallel this helps to flatten the AC in the signal to a DC level. This only works with the compatible alternator I mentioned.
Newer GP can have different alternator control.
