Hey Team P1600 -
Looking for some advice....
I have the '03 LX470 with an immobilizer bypass.
I recently installed a Group 49 Duracell battery from Sams, I really liked how it was bigger and more CCA's, etc, etc, even tho it wasn't the recommended battery.
After installing, the check engine light came on, later diagnosed as the P1600/ECM/Battery/EFI Fuse issue.
I cleared the code (like a dozen times) but it keeps coming back.
After reading through all the posts here (also like a dozen times and coloring all the photos I printed out), I think I need the same fix as @lexs470 had, which seems to be suppling 12V to Block E, which is currently blank on my rig.
Where should I rig the power from for the E terminal?
My hypothesis is that the 'stronger/newer' battery finished burning through the faulty fuse block taking out Terminal E which wasn't a problem previously. Is this plausible?
It doesn't look like @lexs470 will respond.
Do you really have '03 LX470? I am asking because this is not a common problem for 2003+ models. If you have a 1998-2002 model, then you are the 2nd person that I know of, who got P1600 after doing some electrical work to the vehicle. I use the 12V from the fuse holder that is used to power the relay, for the power to "E".
