Warning Lights

[PaulCambio]

Whilst driving the Granturismo today a whole load of warnings lit up at the same time.
ESC, ABS, ASR unavailable. Check suspension and park off.

Any ideas anyone?

Did you change that battery?

If not ABS sensor in the hub may be busted.

 

[spkennyuk]

Did it go off after a restart ?

If the abs sensor in one of the wheel hubs get an out of range signal then it will throw up the error lights your showing.

Early signs of abs sensor failure / wheel bearing play. Will be the errors your seeing which will clear on a restart.

As the bearing wears more you get more and more errors.

Be aware you have no hill hold facility if the error lights are showing.

Battery is fairly new by the look of it and holds its charge well.

I haven’t tried a restart yet. Will do that. Battery reset also needed?

Not well enough. Or an ABS sensor is playing up. But it's probably the battery

When mine did that it was the ABS sensor, hopefully your is the battery.

Left the car for 30 mins and restarted it. Lights came on immediately. Is the ABS sensor an easy fix?

'Fraid not - expensive.....

About a grand or so I think....

Well not hard but not cheap. It's built into the hub. Try a new battery first. Or get it scanned

New battery ordered. Yuasa Silver with a 5 year guarantee. Fitted at my house for £132. Not being lazy, but a frozen shoulder means no heavy lifting!! If that fails @conaero, I’ll give you a call to book the car in.

It should just reset after a restart if the abs sent an out of range message. (Early stages)

As others have said a battery issue can throw the lights but as it happened while you were driving its more likely abs sensor / wheel bearing.

If it doesnt clear with a restart then try a battery reset and charge the battery of the car has been sat around unused for awhile.

Were you going round a corner when the lights came on ?

If your turning left the bearings on the opposite side load up and visa versa.
Slight wear in one of the bearings is enough to throw an out of range error on the abs sensor as it is embeded in the hub. Around £600 a corner on the GT.

It wont be enough play to fail an MOT just enough for the abs sensor to see the play and think the wheel is traveling at a different speed to the other wheels.

The error codes are not stored as such. Its a self check on start up so if your vehicle isnt moving and its early signs of the issue it will clear itself.

You might not see the error again for a few weeks but as the wear increases the frequency it throws the errors will also increase. Eventually it will be on all the time.

Is there a switch to do a battery reset like there was in my old 4200?

No, but there's a thumb release on the negative terminal.

Well done splashing out on a new battery, and good luck, worth the try. Keeping in mind what you are driving, proportionally it’s peanuts. Why do so many cringe at buying a battery, it’s a consumable. Genuinely interested why predominantly the first response with Maserati owners is battery reset. Yes, I agree it costs nothing and can sometimes work, so agree why not ! But on most cars I have owned, disconnecting the 12 V supply to the control systems can potentially causes more problems, requiring additional rectification and headaches. Is it something that has been intentionally built in to Maserati’s as a facility, like switching your computer off and on again.

Cancelled the Yuasa and gone for a Varta which is better and cheaper. Fingers crossed it works. I’ll know tomorrow.

The older 4200/GS cars had a battery isolator. Bear in mind the tech in some of these vehicle was old tech when it was put in the cars. Compare the tech in a 2007 alfa 159 for example to a 2007 4200/GS. The alfas already had voice control , auto light, auto wipers etc. While the Maserati and Alfas for that matter can be voltage sensitive their systems can trip over themselves and as you say benefit from a re-boot when something falls over like the seats memory or windows.

To some extent every fossil fuel car will benefit from the occasional re-boot as things like the maf sensors can go through a relearn process and learn your driving style.

Seems some manufacturers made it more complicated than necessary to change or isolate a battery when needed.

I watched or read something recently that made sense to me anyway. If a battery is low on voltage at start up then there’s not enough power to fully enable all the modules etc. He was saying that some module get full power where some get left out or only get partial voltage hence throwing up a warning light.

That’s exactly right.

This one does wiff more of ABS hub failure but we will get it sorted for Paul

Cheers Matt. Just picked up the new Varta battery and will fit it later today. As expected the warning lights all disappeared when I started the car this morning and drove over to Chi. Still, had a blast on the A27 going home!!
