Hey guys,

So long story short, I need to know if it is absolutely necessary to do a 'proxy alignment' or computer restart you could say whatever, in order for the parasitic draw to register and stop happening????

I have removed the blue and me which I believe was the problem, but still having battery drain and not start. I have had battery tested and it is fine, and I have tested alternator (drove car around to get battery up, and then read at 12.3 then started car and reads 14.4, so alternator is working).

My second question is with TPMS, but again, if I disconnect this as its going to make mileage flash as its looking to connect (mine is out in front left tire), does it really matter if i dont do a proxy alignment?

I was hoping to disconnect these modules and solve the problem as I dont care about blue tooth nor the TPMS, but if all of that work is for nothing without resetting the computer then this is where I am with this.

I've also seen that you can buy something to hook to computer for around $50 to do this? The dealership would charge $150-200 just to hook it up and clear it and I'd rather spend money on whatever tool I need to be able to modify or deal with computer in future, obviously a better deal.

Please advise on if a 'proxy alignment' (I had never heard this term before until now and I've dealt with many cars I guess its per type of car and different terminology), and also any recommendations on what to buy in order to do this that will last me awhile, its a 2014. I'm also curious is that TPMS is a parasitic draw too, but that doesnt really matter because if I remove it too like the blue tooth but cant reset the computer then theres no point, right?

Thank you!!!!!!
 
  1. Year & Model?
  2. Have you measured the amplitude (current draw) of the parasitic drain?
Proxi alignment is syncing all the ECU modules together so that they communicate properly.

You can download the MultiECUScan software and run it in 'simulate' mode so that you can play with it, no connectors needed.

I have similar issues, Jeep renegade with Fiat 1.6 diesel 2018 I’ve downloaded free multi eu scan software, paid €50 for licence
Bought elm327 leads with the colour key sockets … searched proxy alignment on YouTube ✅ shows flashing mileage fix for a 2014 fiat 500 for replacement Bluetooth module …

I also had the tyre sensor on rh front failed high 72 psi .. and all readings faulting blank …

Working through learning what it will do on my car … can’t see proxy link availability for my car so I will probably need a sgw bypass lead installed to acheieve flashing odometer fix .

But I did manage to clear the blank / faulted tyre monitor display.. will see how long that lasts ..

I’ve bought a tyre sensor to fit for £15 .. but need it cloned , that is my next step .. guy on YouTube shows Tps change breaks bead on tyre uses shop vacuume cleaner to pop clear , smart trick .

I’m showing brake service light ( it has new pads and fluid at level ) ..
Hopefully light is due to driving with missing radar module..
Don’t really want car assistance braking when it wants on motorway so happy to delete and proxy align …

But my initial brake service selection on the computer not enabled (sgw module )?

Advice appreciated.

Car service was also re-set, to 12000 miles and 365 days by selecting that option within ecu route and clicking yes after going in to function tab , was 0 -0 previous on dashboard now 12000-365 …
( but will actually do additional oil change at six months )

Battery went flat on computer after 3 hours work ( faffing to get elm327 drivers connected on free version .. then registered and found test link in lower LH corner of welcome page of multiecuscan .

So there is another button left to click on oil list that needs reset on my car .. diesel ..for dpf functions to adjust.. so will try that today..
If you own a Fiat I say it’s a must have kit , but takes dedicated effort and old school knowledge…

It has provided good high end information so far and most valuable service functionality

Could scan and replace majority of my faults with my other Odb tools and skills before I hit the car specific wall !

Will update progress later 👍
