12v battery? Hook it up to a smart battery maintainer overnight and see if that cures the problem.

 

Will give it a try. I have a battery tender I use to charge my Vespa, but haven’t had to use it on my Tonale. Any advice on how to locate the 12v battery to charge it?

 

Oh, this is just the battery.. was thinking maybe the auxiliary battery or something. Will try it!

 

I’ve had the same a month ago. Only the dealership can reset it, there’s a recalibration needed. According to them it was due to a 12V battery charge drop. They also admitted that there have been many faulty batteries they had to replace on the Tonale.

 

Yeah looks like a trip to the dealer it is.. same issue this morning after leaving the 12v charged overnight.

 

You could try a hard reset — ie, disconnect the negative battery cable for a few minutes.

When you do this in a Giulia/Stelvio you’ll get all the warning lights after you reconnect the battery and start the car.

However, they can be cleared by doing a simple steering wheel reset procedure. You start the car, turn steering to full lock left, then full lock right, then back to center position. Turn off car, then restart and all warnings are gone.

 

When I had the light show myself, I tried the steering calibration procedure, as suggested, but it didn’t work. Tried at least a few times but no effect at all. Unfortunately, only the dealer could clean the errors and re-calibrate. BTW, when it happened to mine, it was plugged in and charged. And I had been driving it everyday, not like it was sitting in the garage. The dealership were not sure about the actual cause. They only found power failure in the logs and assumed there’s been a voltage drop. But how could that happen when the car has been plugged in and fully charged? Also, they said they replaced a lot of faulty 12V batteries, apparently a weak component, the most common issue being the electronics in the battery are not correctly reporting the actual charge level which can lead to empty battery. They didn’t change mine and I’m still worried it might happen again.

 

The only additional thing I can suggest, is that when you do the recalibration on a Tonale, HOLD the steering wheel at the lock FIRMLY for three seconds in either direction. After re-centering the wheel, turn the car off and restart. A Giulia and Stelvio are simple lock-to-lock, but on a Tonale you have to hold it at both locks.

 

This was indeed the trick. When you turn full left or right, there is some pressure that turns the wheel back a bit. Unless you’re holding it tight both ways, the procedure doesn’t work. Now just trying to reset the rest of the warnings/lights..

 

Thanks for the suggestion. Tried it a few times with no luck. Looks like a trip to the dealer, and burning serious gas until I can get an appointment.

 

Actually that reset process got the vehicle in a much better state. After starting, I no longer have the red “service power steering” and all other warnings. The vehicle now drives in any mode, and everything works. But the “service engine” warning comes on, and various dashboard lights are illuminated. Not sure what else can be done to clear all those..

 

I am having the same issue and the recalibration eliminated all the warning lights and now I only have the check engine light. How did you resolve?

 

Down to just the CEL now.. can I just clear this with my OBD and see if it comes back?

 

Cleared the CEL and all is good now. What would you guys do? Just keep the car on a battery tender while away for more than a few days, or pursue a battery replacement? Not much I can do now that I’ve reset and cleared the code, but glad you guys saved me a trip to the dealer in any case!! Thanks again!!!

 

What code did you have? It is important to note which code caused the concern, depending on the code, if you delete it, the dealer will have nothing to go on.

Also, keep in mind that you are only accessing the engine PCM with a generic OBD scan tool. The engine PCM, the TCM and the battery pack control module can all set the check-engine light, while the other 20 or so modules cannot.

If it recurs, make sure to note the code and let us know. Personally I'm leaning towards an actual concern rather than a battery issue. Most likely a concern that can be alleviated by a software update at the dealership.

 

There were no codes on any of the 4-5 modules the scanner was reading from. Yet when I cleared all codes, it reported codes were cleared and then the CEL was gone. Was hoping to at least read a code before clearing, but nothing showed up.

 

Last time I was at the dealer they returned my vehicle with the OBD still plugged into the port. Should’ve kept it, but my honesty got the best of me!

 

I plug the Tonle to the trickle charger once every 6 months, the battery has never died on us though.
We ordered the car and took possession about 3 weeks (early January'24) after it arrived from Italy...when I read about dead batteries here I decided to charge the 12V in mid-March, it was about half full. A couple of days ago I charged it for the second time, as mentioned on another thread, after 5 minutes of being connected the C-Tek charger showed 3 out of 7 lights.

 

Funny how Alfa published a video explaining how to perform the steering recalibration 🤣

 

Curious timing indeed..
