Hi,

Car: Bugeye UK WRX (MY01)

had an ABS check light come up so took it into garage. They plugged in the Subaru SELECT monitor and it threw up a code 54 (I think) - pointing to the ABS pump.

4 different pumps have gone, all other possibilities have been checked and still no joy.

I also have a CEL due to low alternator voltage.

I think it could be related to a dodgy wiring loom??

I haven't had an arch liner on my passenger side front wheel and I believe this houses quite a few electrics? Could this be the reason?

The garage has suggested a dodgy earth or something so they're going to earth direct to the body for the ABS and see if that works.

Any other suggestions?

Is replacing the loom a big job?

It's doing my nut in!!!!

 

To refit another loom would be a nightmare mate i know iv'e had mine in bits ,the loom as you mentioned going under the wheel arch lining is a sprag off (excuse the pun)from the main loom so all would have to be replaced back to the ecu .

Can you see visible wear of your loom ie exposed conductors or broken wiring if its a few specific cores these can be taken back to the point of damage and re-soldered with new wiring to the specific unit .

Either way its a fairly big job capable by any reputable auto electrician.

 

I'll check properly in the light of day but have a feeling it's related to something like the loom!

 

How to say matey,with ABS is sometimes hit and miss...
Last time when we are have ABS problem,we are change all sensors(first time has been Passenger side,later on has been driver side etc.) and we have same problem and again after replacing all sensors,everything suggest ABS pump is gone,at our garage say,its too rare have ABS pump problem,but changed on our request,and what happens we are still have at this time ABS problem...

When we are changed our brakes to K-sport front and rear, Neil@Slowboy Racing said our rear hubs looking like are damaged,we are changed and he said this can cause our problems with ABS and this has been our case,after replacing rear hubs we have ABS working.Sometimes easiest thing is right thing...

Really before you are putting your car apart with "dodgy" loom,i would suggest have look on your hubs if they're OK,can be your too case like our one.On hubs are ABS tone rings/wheel which can cause this


Good luck matey

Thanks for that Jura mate.

I'll tell the garage to check. Reason I thought it could be the loom is because of the CEL showing for low alternator voltage.

I've done all the obvious checks and used a multimeter, battery has never let me down etc.

Seems suspect that I'm getting two electrical errors!

 

Not sure,but you are checked with multimeter voltage etc.?

In our case ABS error caused damaged hub.

If you are getting two electrical errors,have you checked too alternator?

Alternator got checked when the CEL issue occurred. I'll see wha happens tomorrow - hopefully its something small! :-)

Thanks for your tips Jura

 

Latest news - Garage has used the official IM/Subaru fault finding manual and has made sure everything functions as it should, within parameters etc.

Still the same error!!

They've tried 4 different ABS pumps so what else could it be?

They have also replaced the one damaged hub that was toe'ing in but no difference!!

They are scratching their heads and so am I !!

Anything from anybody??

Fecking car is really winding me up
