2006 GS 300 third generation
Battery keeps dying. Found about .250 amp draw. Pulled fuses and found it is Fuse 43 (41 also) which is the MPX-B or Multiplex Communication System (page 568 of users manual). Anyone know where this module is located or if replacing it would seem the next step?

thanks

 

On a car with as many electronic gizmos as ours, 250mA is not that bad. How long are you letting your car sit for? If it's dieing that easily, replace the battery because its time has come.
