TCU Location - SOS Limited Functionality
#31
It looks to be a bit wide to fit into the battery compartment but worth a try. On the factory battery it is a 3 wire setup but the red and white wires go to the positive side and of course black to negative. The factory battery is still our of stock every place I have checked,

Replacement battery
Factory battery measured @ 3.99VDC
replacement battery measured @ 3.86 VDC as expected. the replacement battery fits perfectly in the TCU unit. Unfortunately the SOS alarm is still in solid. I will give it an hour or so to hopefully reset. More to come…
Soldered factory connector to replacement battery
Replace battery installed/ currently in the testing phase

Thank you @Paulwilson for this effort. The current battery has 3 wires, red/white/black. How did you wire it up, picture is blurry?
