Title: ECU/Relay box removal
Post by: GaryBC on 01 February 2010, 16:46:17
I've got an ABS ECU change coming when the weather warms up!

To give myself a bit better access I want to pull the relay box to one side. I've had a quick look at it and it's not immediately obvious how it is attached.

Anyone got any pics, or a description please?

The car is a 2000(W) 2.5 petrol.

I have another question regarding abs ecu: is it possible that the ecu has failed, cause i have no abs and tc, but still have speedo and servotronic working fine? I've bought the car already with that problem and have driven it for two years with no speedo or servotronic faults...

Sounds more like a different issue, duff sensor perhaps.

The car is a 2000(W) 2.5 petrol.

got no pics but had to do this my self and this way is the easyest way i found

remove battery
completely remove fuse/ relay box
was held up fingering how to undue the 3 big round mulitplug thing
you know em when you get to them
you unduo em by unscrewing then the pull out



drain coolant and remove top radiator hose
not stictly nessersery but make it far easyer if you remove power steering reservoir as well

then for get try to undo the 6 torx screws on ecu yet

losen the two nut that hold the whole abs unit down
now you can lift the whole unit up by the brake lines

dont go mad pulling it just lift enough so a m8/ helper

ban then undo the 6screws
for that you need a extra long torx bit t20 if i remember right size

refit in reverse of above fill coolant
put some steering fluid in power steering reservoir

and dont for get to bleed power steering.

ie start car power stering will ushally make a right nose dont worry about noise

now with out moving/driving repeatedly go lock to lock on steering and it will shut up

recheck levil and top up if need be

then just check a day or so later after a drive in case
and top up if need be

other way is become a contutionist with a fexable driver on them torx screws and some tape on end of torx bit

and a hole lot of swearing and tool trowing
and bloody knuckels

trust me the above is the easyest way by far
and i could do it now in about less that a couple of hours and 6 coffeys

for the price of the radiator top hose just get a new one while you are at as min was so stuck on i had to cut and it was buldging anyway.

It's the fuse/relay box removal I can't figure out! Where are the attachment screws?

here just had a look

and remembered i dident need to take the whole lot out

you just need to pull bat ,remove small fuse thing with the large fuses in it that just clips slides on



if i remember rightly you have remove fuses and wireing with fuse holders before you can un clip box

the fuse holders  sort of slide/clip in to plastic tray



then i just removed that a hinged lid/cover of relays with the fuse box bit still atached as the plastic lid will un snap at the hinge

the hinge just clicks/snaps in
you see what i mean if you look


i also removed the ecu thing in main box that clips on
that just slides out

as that get some more wireing out of your way

just take your time it aint hard to figer out once you start pulling bits out

the only hard bit is getting the 6 torx screws in and out of the abs ecu

and if there s two of you and do like above that prity easy to do

it looks a lot worse than it is
