TPMS fault on DBS 2010

[David555]

Hi I have a DBS 2010 manual 2+2 and recently changed the battery
Since then the AC has not been working and the TPMS has no power lighting it up and fault warning on dash

I have tried everything every fuse and fuse box as I have 3 but nothing.
There are a few threads on here from about 2015 but not really able to help me.
Firstly is there a specific fuse for the TPMS and where is it?
I have done a whole load of fault finding including re connecting battery and going through reset modes

I am hoping there is a simple fix!!

Thanks in advance

It may be coincidence, that one or some of the tyre pressure sender batteries has failed.
There is a topic somewhere here, describing how a new sender unit (inside the tyre) can be replaced and programmed.

I had a constant error light for some time and eventually, just had the electronics coded to remove that light.

For your age car, you do not require a TPMS by law. Think that became effective from about 2012, so your MoT person (has anyone ever seen a lady MoT tester?) would be wrong to issue a fail for that warning light being illuminated. Best of course to fix a note on the dashboard in advance of a test.

Hi thank you I am moving the car on so I would prefer it working. I don’t think there is power getting to the TPMS from source and that’s why I’m thinking along fuse somewhere…

Thanks mate

Aston Installations or a decent independent will disable the system for minimal cost so no more warning lights though when my sensors ran out of juice a year ago (also a 2010 DBS) I replaced them as it’s a keeper and I like everything to be 100%.

Haha I am wanting to keep mine too
I know Aston installations well they did my car play new cams front and rear and new screen for the map.

If I don’t sell I’m going back to get the headlights done with their ventilation system they have and mini fans so that’s a nice upgrade.

I will mention it to them to try fix or disable with option to update later

Thanks mate

I think I spoke to you outside the hotel in Felbridge last week . Great looking car

[David555]

Had the same problem on my DBS (MY2010, Volante, Manual), the vendor who makes this unit does not exist anymore. Can not easiliy be repaired or replaced. My dealer also disabled it.

Did look at those 3rd party tire pressure kits (eg on Amazon), but not made the jump yet, and I don't miss it for now.

Cool thanks. I have seen the tpms control unit on eBay from a db9 for a £100 so I may get that. I have a few power tests to try yet so I’m going down that route for now. I would prefer it working tbh rather than give up.

Thanks all.

Great, keep us posted if/how this works, I might do the same 😎

[David555]

Will do

I bought the TPMS cancellation kit for 32 pounds and never had a problem since.
