ABS unit will not turn off

[MercuryFree]

So i was just driving along and my abs warning light goes on, gave the brakes a few testing activations and they worked so that's a bonus, but upon turning the car off, the abs unit/pump thing stays on. Full bore. Nothing short of yanking the battery fixes this (as I don't know what fuse to pull as it's in japanese).

• Is it fucked?
  
• Is there anything I can try to remedy this
  
• which fuse do I pull?

Hopefully somebody's awake...

Give the ABS pump a tap. Sounds like a sticking relay. It will drain your battery pretty quick if you leave it.

Yeah it's sitting with the battery unplugged atm so as to not do what everyone else with this problem on the internet did haha.

By 'tap' do you mean grab a wrench and tap the side/top of the pump with it? Just checking before I go whacking things

Yup, just need to shock the relay into releasing. Start with light taps and work up to bigger. Maybe use a piece of wood so you don't damage the pump.

It kind of works, turned it mainly off but was still making a little bit of noise, if I hit it again it goes off for about 2 seconds and then starts up again (albeit to a much lesser extent than before)...should I hit it harder? ;D

HOw much brake fluid do you have in your master?

You most definitely should! I have mental images you you whacking your pump with a plank of 2x4

[Guest boostin]

It sounds knackered then. I would look at getting a replacement.

First thing I checked, fluid level is normal

Just the relay or the entire pump?

Should I just be looking at getting a new relay to start with or just get a whole abs unit?

There was a diagram and 'how it works' but no actual useful troubleshooting information . Thanks anyway though

Try pulling the relay out and see if it turns off.

Yeah did that last night and it worked. As did unplugging the relay power plug (but not the ABS unit ones)

Where worked = turning off

There's 2 relays on the driver's side. Pull 1 relay out at random and put back in. That will stop the asb pump. Take note of the relay. If it does it again. Take out same or other relay and work relay which is the dud. Replace one or both with bought one (~$80) or from wreckers.

I can only see one relay?

[RS.YES]

F*ck I've fallen victim to the same problem but now my battery's dead (5am in the morn, just b4 I start work). So have to fork out for new one.... So where exactly are these two relay's are they right behind the dash on the side above the fuse box or are they in the engine bay?

What causes this sort of problem?

[MercuryFree]

Update: I'm lazy so I've just left it unplugged. Plugged it back in and it doesn't run full bore anymore, score. However I'm now getting the ABS light on again even after clearing ecu. Attempted to work out how to get a code from it to no avail, as I cannot find what this picture is talking about

Does my car use this system and some muppet has done something to my cables, or am I barking up the wrong tree here?

Cheers...

Edit: Upon resetting ecu, the abs light goes away until I go above 10km/h or so, reading the manual they keep mentioning something like this. Don't have to brake or anything to make it come back...

Note that pic is for LHD. It's a grey connector on a bracket screwed to the side of the heater box.

Still can't find it...sigh. Cars do this on purpose to drive me insane.

[Guest boostin]

Take a photo with the camera sitting on your fuel flap release lever and looking across to your clutch pedal.

[Guest boostin]

It should be right behind the yellow connector tied to the side of the heater box.

Here's mine, sorry for the crap phone pic...
