Technical Error code PO480-13

[Biet]

Ducato 2.3 148 pk 2016 Euro 5 Livingstone Rollerteam duo.

De foutmelding 'koelventilator 1 circuit onderbroken' en het direct optreden van de noodloopmodus na het starten zijn nu verholpen.

Onderaan de zekeringkast onder de motorkap bevindt zich een zwarte connector; dunne draden lopen van hier naar de ECU.
De grijze en grijszwarte draden komen na een verbinding op vijftien centimeter in een krimpkous samen, waarna een grijze draad verder loopt naar pin 72 in de ECU.
Het probleem zat in de krimpkous; de draad was groen, geoxideerd en gebroken. Ik heb hem opnieuw aangesloten, de foutcode gewist en nu werkt alles weer naar behoren.

Hello,

It looks like another problem caused by the 'classic' Ducato water leak into the engine bay.

This damaged cable probably is the 1st one you've discovered. More to come

There are threads here that describe how water gets into the engine bay and how it could be repaired. However there's no terminal solution

I'd disconnect the battery (in the safe way), wait some time for the parasitic voltages to drain (you could also try operating some electrical switches) and disconnect the ECU connectors to check for water damage. Once checked, use some special lube to protect the terminals and the seals inside the connectors. I've asked a question which product to use here:

Electric contacts protection spray

Hello, I'm looking for good protection spray to protect electric connectors. I know such things exist, playing with a part for my non-FIAT daily I got from a breaker once I removed the sealed plug with like 20 connectors inside, they were all covered with a blueish fluid. The donor car was...

Check the other connections in the engine bay: once you find where the water comes from it would be easier to track the looms that might have been impacted.

I've even read about some cases where water flowing down the looms got into the BCM

English translation for anyone who is interested.

"The error message "cooling fan 1 circuit interrupted" and the immediate occurrence of the emergency mode after starting have now been cleared.

At the bottom of the fuse box under the hood there is a black connector; thin wires run from here to the ECU. The grey and grey-black wires are joined together in heat shrink tubing at fifteen centimetres, after which a grey wire continues to pin 72 of the ECU. The problem was inside the heat shrink tubing; The wire was green, oxidized and broken. I repaired it, cleared the error code and now everything is working properly again."

@the green vanper It is good to see you posting again.

Interesting bit about the BCM. It could explain why so many failures in a device that is located in a more environmentally friendly location than under the bonnet.
