Chrysler Software Update

[Msd26129]

I have a small issue with my 2004 grand voyager . My central locking stops working and I have to remove the IOD fuse for 5 minutes so it resets the bcm then my central locking will work then after a day or so it stops again .. Now I have been told that there is a software update for the bcm that will rectify this but my local chrysler dealer said they will only do this if I have a full service with them costing £££ .. My question is are there any independent garages with the same software so they can update my bcm without paying a small fortune ..

 

Thanks in advance

not sure about independents having the right software but one thing you can try is instead of taking the fuse out for a  few minutes, try taking the negative terminal off the battery for a good 15 minutes. Reason I suggest this is that it will do a complete reset and make the IPM (integrated power module) forget any faults it picked up and start all systems afresh. It is a long shot but it worked for 2 faults that my grand voyager had with the speedo needles not lighting up when lights are on and also it kicked my folding mirrors back into action.

if that fails then go try the software update and you shouldn't be told that you have no choice but to have a full service, just tell them the service was done not long ago by a friend can't sell you something that is not needed or required and irrelevant

Your dealer cannot say that! They may charge a bit of time for investigation to see if its relivant, but the time for the bcm flash is 0.5.
