I’ve read through a couple posts on here and haven’t found anything that’s helped yet.
So. I got a new battery for my 07 is250. The terminals were backwards from the old one and I put the battery on backwards. Rookie mistake. It blew a fuse in the fusible link box. Replaced that. Put battery in properly and now the car is in limp mode. Check engine light, abs, and traction control light are all on. Put a paper clip in the OBD port and got DIAG VSC 51&43.
Ive tried disconnecting the battery and pulling the ecu fuse to no avail.
Thanks.

Disconnect the battery terminals
Turn on lights / Press the brake pedal a couple of times to make sure all the electricity is drained out
Reconnect the battery and see if that helps.

Make sure all the fuses work for the throttle body. It's on the same fuse box as the ecu one. I remember a member awhile back had a similar issue. Better yet check all the fuses with a DMM, OR TEST LIGHT. Eyeballing it ain't going to work. As who knows how many fuses may of blown.
