Technical Air suspension

[Bro Tegla Ben]

Hi, my Ducato 2014 multi jet 130 factory fitted air suspension problem compressor not running.
I've just just replaced air compressor air bags and pipes, all with previous faults ( assume air leak caused overrunning of compressor which had ceased and blown main fuse now changed), on turning ignition on and starting the engine the compressor does not run. The two fuses 40 and 7.5 A next to battery are ok. The message on dashboard reads check suspension fault. I have tried Odb2 link with no results. Can anyone please advise or have wiring diagrams please

There is quite a bit of detail in the

Fiat Ducato Training manual GB.pdf​

downloadable from the forum here:

Fiat Ducato Training Manual

Very useful guide for Fiat, helped me identify parts and how to dismantle them.

www.fiatforum.com

(Page 133 on).

I think you're going to find something that will properly read the codes for any progress, however.

Thanks, yes pretty detailed found another fuse to no avail and yes some detail for Obd which may help. I need to get Obd reader would you no what model to go for (The garage I used tried but failed to find any thing for suspension)
thanks again I can see it will help in other works I need to address too.

If anyone can help with wiring diagram for the suspension compressor it would be greatly appreciated.

The best diagnostics for the Ducato is Multiecuscan, you down load it to your computer and connect to the obd port with cables and different adapters for different modules like airbag ecu and engine ems. You can get the software direct from Yani (the author of the software) Whom I think is a member of this forum. You can try it for free but limited functionality then pay to licence your copy for full function.

And the cables from Daniel, full set

Thanks Mike will look into it.

If you have the laptop to run it on, Multiecuscan makes good sense, since it can diagnose (and adjust) most things Ducato. The support info on the Multiecuscan site suggests it has capabilities for the air suspension module(s).

Hi. I’m not there yet but the report points to a volt drop between components. I’ve been using multieuscan to pump suspension every 3 -4 months. The vehicle has had bad earth issues so fancy that first port of call just need to identify where the cab parts are and associated wires.

That’s as far as I have had time for I’m sorry to say. So if anyone can identify where the Aux control H115 & Body control Modual M001are that would help with motivation moving forward. Thanks Ben
