Stability/traction control issue

[Netstar1]

Hey guys,

My '07 LS2 has developed a very annoying issue!

The stability control keep turning itself off, which means I get three "bings" and a warning in the dash.

This keeps happening! It used to happen from time to time, very rarely and on bumpy roads etc, but now it's too frequent to ignore.

Just drove a 15 mile, about 25 mins driving trip and it literally binged at me at least 15 times!

Anyone had a similar issue and can point me in the right direction? Thanks all

I doubt it will be much of a problem (hopefully) always good to buy a cheap code reader like the MAC ones on the europarts web site, they will usually let you know the simple problems that pop up.
Plugs and leads problems can make this happen, when were they last changed? ABS sensors and O2 sensors also quite common.

Sounds similar to a problem I had on an LS3. Intermittent ABS and Stability control warnings. Fitted new ABS Sensor, then a mini loom but ended up solving it by installation of a new wheel bearing.

Thanks guys,

I dont get any other errors or ABS warnings, but the sensor kinda makes sence. IM gyuessing its a sealed unit with the wheel bearing? Code reader it is!!

Its been serviced with last month, so confident there is no plug or lead issues as these are new.


Thanks all

Take the engine cover off and check the connections I had the same problem, down to vibration and a loose connection

When it was serviced did they Change the leads and the plugs ? More often than not the plugs get changed and not the leads, just worth making sure the leads were changed, leads do not like to be pulled about.

Ah will be watching this with interest... my LS2 Monaro has been doing this for about a year now. Used to only happen very infrequently when absolutely nailing it, but happens all the time under reasonably exciting levels of acceleration.

I figured it must be a sensor, and losing traction control is no major but the bings do start to get annoying. That and the wife constantly going 'is there something wrong with the car? Are we all going to die' or something like that...

[Netstar1]

Thanks for all the replies guys! I'll check them all out.

Can anyone let me know where these connections might be? No engine cover as its S/C.
Thanks all

If I remember correctly there are 4 connections on the left and 4 on the right and there blue, monkfish plugged it in and found the loose connection in seconds lol.

Another possibility?:

There is an ECU patch for the LS2 E40 ECU fitted to these cars, so if all else fails, get the patch applied.

It can be done by anyone who has efilive but will cost at least a flash license and a friendly efilive owner.

You're describing exactly what I get on my '05 CV8.
There's a thread about the 2 rear ABS sensors air-gap to the rear drive-shaft reluctors being too small (by about 0.5 to 1.0 mm, should be 1.5mm).
I've tried removing the ABS sensors so I can shim them to increase the air-gap but they won't budge. The sensors being seized is a known issue.

Thank you for the info - greatly appreciated. Any idea on cost to fix? (sorry Netstar1 for the highjack!)

this has happened to me twice now....first time it was the rear harness thing...this time when it went t/c was going on and off and the speedo went into meltdown.i assume it was the harness shorting out again.

I had this on the Maloo mine was a loose ht lead

Seems like this is the issue. None felt like they were loose, but pushed them all home anyway to be sure and the issue stopped for a whole 50 mile drive. It binged once when I was on the last mile. Must have worked its way loose again due to vibration.

Going to disconnect them all, clean the contacts and hopefully that should solve the issue.

Thanks everyone for your input.

Yah I love it when a plan works lol
