360 modena "suspension" indicator light

2 faults that will come up with a low battery..ASR, and suspension.

Buy a good and proper battery charger. NOT a trickle charger. They are completely different devices. Get that battery to 100%.

Clear the faults. Drive the damn thing everyday for a week. See what happens.

 

Anyone know where I can purchase this rear vertical acceleration sensor in the US or Canada? Ricambi seems to be out of stock for good.

 

You could try your dealer in Toronto.
Eurospares in the UK...they ship worldwide.

 

Before replacing, clean the grounds on the rear frame.section. best access is through the wheel well.

 

I don't see the purpose in this, Tom. All the wiring for the rear vertical sensor goes to the Suspension ECU. No rear grounds involved. Of course , it doesn't hurt to clean grounds at every opportunity.

The main earth for the suspension system seems to be 14C.. in the cabin.

You are showing the forward system. The rear system is different. Clean the grounds in the wheel.well as a starting point.

 

I originally ordered one from Scuderia. I order a lot from them and the price was great. The ETA kept getting pushed back later and later, so I also placed an order with Ricambi. I just received mine, from Ricambi, today. Sounds like I got lucky.

Are these obvious and easy to find?

 

You gotta kinda hunt around, but once you see them, they are easily accessible. A 13mm wrench and some sand paper is all you need.

 

According to the wiring diagram, no suspension sensor has a ground, front or rear. The only ground is for the ECU as shown above. i.e. 14C

Main harness grounds are in the left/right rear fender well. Every sensor needs a ground. It's a simple cheap check that was a well known weak point. Not saying it will fix the issue, but it an item to check.

Swapped out the rear sensor. Warning light went away. No more defaulting into sport mode / rough ride. The gauge cluster is nice and calm.
Should have done this a year ago!

 

Just got my sensor from SCUDERIA parts. Was an easy swap out. No more warning indicator. Thanks all.
