ECU reset for 90 LS400/Celsior

[Celsiorous]

Hi,

Ive had a search but cannot find instructions on resetting the ecu via the fuse on a LS400. There are heaps of pictures and instructions for soarers but the fuse box seems alot different. Has anyone got a pic they could post of which fuse/fuses to pull in a 1st gen LS400?

Cheers

Just disconnect the battery for a minute or two.

Or you can unplug the MAIN EFI relay in your fuse box under the hood.

thanks, lex do you know what to pull to reset the trans aswell?

If you have a Celsior or LS400. The tran and the engine is the same ECU. I would assume by pull the Main Engine Relay will take care of that too.
