Intermittent tone sounds when turning on NS 2009 3.2TD

[LukeB]

Hi All,

Wondering if anyone here could help. I have a 2009 NS 3.2 TD, intermittently when turning the car on, I get a constant tone from the car. Sometimes it will turn off by itself and others I need to turn the car off and back on then it will sound again and turn itself off after about 10 seconds.

It's come on a couple of times now as well when driving, not when starting the car. There are no open doors, no accident damage, nothing out of the ordinary that I can tell that would be causing this.

Video of the issue can be viewed here

Thanks in advanced for any help you can provide.

Cheers
Luke

Thanks for letting me know, I appreciate it. I have now fixed the link.

Your ABS and Active Stability Control lights on the dash are staying on after you started the engine, they should only illuminate for a short time after start up and go off. The buzzer is a warning that there is an issue with the braking system linked with the lights staying on.

I wouldn't be driving it until fixed bud.

That sound like there is not enough pressure in the HBB accumulator. My guess is that the HBB motor failed (the accumulator itself fails too - some diaphragm: https://www.youtube.com/watch?v=Y1sBSiS1vnw)... And yes, I wouldn't drive it before fixing it...
Here is a similar video for the MK3, but I think these are similar...

Thanks for the advice, I have it booked in to an auto electrician next week. Hopefully this will help narrow his search.

Thanks again all, much appreciated.

That sounds like the warning you get when your traction control is overheating when going up a steep climb. thats part of the braking system. I'm surprised the check engine light isnt on.

Thanks all,

I've changed my service to a Mitsubishi service centre, since it's likely the braking system. Will post an update once they have determined what it is.

Oh Lord. Not MM

If it's the motor or accumulator be prepared to bend over at MM and fork our around 1,000s of $ and I mean 1,000s. MM will replace the whole master cylinder/booster assembly as it comes as one part.

I have a motor and accumulator you can have FREE if needed. My whole assembly was replaced a number of years ago as it was bypassing.

Thanks BruceandBobbi,

I'll see what they say is wrong with it before I commit to replacing anything. They said they should be able to determine what is wrong with it in under 2 hours.

I'll be in touch if it is the motor or accumulator, thank you very much for your generous offer!

So the car is currently at the service centre. They have said their diagnostic tool isn't connecting to the computer in the car for some reason.
Anyone had any experience with that happening and what they did to fix it?

[crispus]

Not very helpful, but I know that the Pajero is pretty picky with the diagnostics tools... If their tool usually connects to this, all bets are off

[crispus]

Hopefully being more helpful
There is a Mitsubishi diagnosis way which doesn't need a diagnosis tool: https://www.youtube.com/watch?v=lCn3wh6gqwc
Here are the possible codes for the brakes:

Thanks all,

I took it to an auto electrician today and he connected to the computer and got the codes without issue. Didn't do anything to it, just worked. I also got a bluetooth OBD connector which also worked and got the codes. $65. No idea what MM had going on.

Turns out it's the HBB. For anyone who comes across this issue in the future, Mitsubishi quoted $4600 + 4-6 weeks wait time.
