How do we keep from losing memory when replacing battery?

 

[rbarrios]

like the radio?

or parameters set in the Trans/engine?

I think the latter is lost after about 20-30 min (like on the Trailblazer I have).

but overall--- some shops use this...
you can make your own- just have to know the polarity to make your own connections--- or get this on Amazon for $10+ $6 ship

Saves the memory of the on-board vehicle computer when the battery is disconnected
Plugs into cigarette lighter
Use with 9 volt alkaline battery (not included)

this is one I recently saw... it plugs into the OBDII port- and saves memory via its always on connection.... as some automakers TURN OFF the cig lighter/power ports when key is removed-- but in the Lamndas the power ports are always hot.. so you just need the 9 volt battery type.

this is something a shop would get- that makes lots of battery replacement-- and reprogramming stuff is not to their advantage...
