Poncho
Car: IS200Se

Here http://www.lexusownersclub.co.uk/knowledge...ex_v2&id=38&c=5 it says Remove the 20Amp EFI fuse and Remove the 15Amp ECTS fuse.

I have lifted the cover of my fuse box and this is what it says on the left side:

25A - EFI
10A - Turn-Haz
20A - Radio no.1
10A - Horn
20A - AM2
15A - ECTS
7.5a - ALT-S
20A - ECU-B1

I know I have to pull the 15A ECTS but which is the other one as EFI is rated at 25A? Please assist. Thanks smile.gif

That's weird, in my car they are specced as stated in the KB! What year is your car?

Just remove the EFI and ECTS fuses, that will do the job, there is afuse remover in the box too, I never noticed the first time I looked!!

Yes it's the EFI one. Does it say 25A on the cover or is that what the fuse is? Maybe newer ones have a higher amp fuse.

Might be worth upadting that article Col if they're putting higher rated fuses in there?

Poncho, one they're out just leave the car a couple of minutes, then pop them back in and drive off - I noticed a difference straight away when I put my foot down on the road out of the house, the power kicked straight in as opposed to having lag before the reset...

Yup, will do smile.gif

I guess the Oct 2001+ models have a larger fuse due to the extra electrics on them (Electronic Brake force Distribution (EBD) and Brake Assist (BAS)). I'll amend the KB

Last time I did this I lost the fuse removal tool under the engine. Had to use a stick with bluetac on to get it back. blink.gif

i dropped mine and never did get it back!

I once dropped one of my spanner bits in the car and never did find it - could hear it clunking about for ages then eventually it fell out!

Let us know how she feels Poncho when you get back in - might reset mine again just for the hell of it (haven't reset it since the twin exhaust went on!)

I dropped my glasses in the engine once. Sigh.
