VE ESP problem

[Z3RO]

Hi guys

I recorded a video of what the ESP does. You can clearly see the speed, RPM and digital speedo.

Take a look guys and see.

How much throttle are you giving her when this happens? 7/10?

back to Holden for you

None at all. this happens when I slow from braking or removing my foot from the accelerator.

[jamesmp]

Sounds like you're removing your foot from the throttle rapidly and hitting the brakes aggressively. My VE loses traction when you do that. How much brakes are you using?

[Zerone_V]

Use a scantool, and see what codes it throws

When I took that video, none. I just took my foot off the accelerator on a flat road. I never press brake and accelerator at the same time. I am in Brisbane too, I'll show you my VE and what it does in person if you're on the southside. I can't figure it out.

I took it to Holden and their scan tool said too much air through MAF and throttle and throwing up fault because ESP is on the same side as the sensor faults.

I swear if anyone could fix it or tell me exactly what is wrong it would be a miracle.

[jamesmp]

I'm on the west, so not too far away. I am not hugely mechanically minded but could check it out next weekend. Send me a PM.

If Holden have checked the codes with Tech2 and told you what was causing it, did they say it could be fixed etc? What mods (besides pacemaker headers) do you have on the car?

Sometimes ESP/ABS/Stability can be set off is there is a calibration error in the BCM or an ABS sensor goes funny. Also an engine miss will cause ESP/Stability control to come on for a few minutes and clear itself. But there are probably hundreds of things it could be related to/

Pacemaker short headers
2.25" cat back exhaust, no mufflers
Airhammer CAI
Lowering (professional, not angle grinder)

That is all for my perfomance mods, the rest are visual.


I just found a tune from Castle hill performance in Sydney, you send them the PCM from your car and they send it back to you by post and it takes care of the CAI problem I am having and it's a tune. I must admit I am a bit sus about ripping the PCM out of the car and sending it to someone. Not that I would even be able to look under my bonnet and point out my PCM. But... If it will solve all of my problems and also be a tune it will be the best $500 ever spent!

You might want to have a look at this thread by MACE.
LSX LXX V8 Remote tuning service :)

They mention in the thread that they also do V6 Remote tuning.
No need to remove the PCM either

Im looking at doing this in the next month or so.

As for the ESP Traction faults.... It is very hard to say if the LEAN condition does affect the traction control.
Ive played around with clusters, and its very very easy to accidentally disable these at the first sign of anything wrong.
It may have been the case that the BCM is trying to correct for the LEAN condition by adjusting the throttle body outside of its set params, and that may be disabling ESP ????

Stranger things have happened. I have heard stories of ESP being disabled upon brake changes, lowering, wheel and even in some cases tyre changes.

I also threw a OTRCAI on my car last week. It lasted to days before I decided to give it the flick.
You could tell the BCM was having a real hard time trying to adjust to it. The idle quality just got worse and worse the longer I drove it.
I never got a check engine light, but the way thing were going, had i kept it in there, it would have come up and bit me in the @$$ in around a months time.

How did you know to take it off, Zerone_V?

Thanks for the advice Zerone. I rang Mace and they turned me onto Power Torque and Chip Torque here in Brisbane. I rang Power Torque first and they said yes they can fix my cars problems of tune it. I am going to pop into their shop today asap. He said there has been a VE in there recently with the same problem that mine has and it was the throttle control that needed to be replaced. I am closer to a result now... Watch this space this afternoon.

First rule of F$%^ng with anything you dont know much about.
Change one thing at a time, and if what you changed made things worse, then undo your changes.

I had heard that fitting an OTRCAI would eventually bring up the check engine light, but I was hoping the thing would be drivable / the BCM would eventually adapt.
(My old Falcon with EEC-IV could adapt to everything that I threw at it).

I figured the OTRCAI was well outside the limits for the BCM, so I figured remove it, and try and revert back to stock. Which luckily worked....

[RiCeY]

BCM is body control module and has nothing to do with the engine.

ECM controls everything engine related.

[Zerone_V]

Sorry, I come from a background of Ford / Falcon Terminologies.
I know my round most modrn Falcons and Territories, but the Holden stuff is still very new to me.

I am used to terms such as BEM, EEC, PCM, SCM and ICC.
So I often find myself trying to convert GM Terminology to Ford Terminology, and trying to relate VE stuff that way.

So when someone mentions ECM, in my mind im thinking EEC / PCM
BCM = BEM
SIC and DIC is the same as ICC
etc etc....

[Z3RO]

I got lost on my way to the tune shop and bought brand new 20's and tyre package... Need to save money again hahahah.

[jbray1984]

Wish I had that kind of spare cash just lying around lol.

I HAD that kind of spare cash. Now I don't.

Wise advice indeed.....

This has been an issue in my VE Sv6 and it was the beginning of a rear left bearing needing replacing.... because the ABS and stabiltility control sensor is really close or infact connected to the wheel bearing, if that makes sense..... It started to flash only when i turned right due to the wheel bearing issue but then continued to flash every single time i started the vehicle, then not long after the abs light was constantly flashing... Making my car one annoying beeping flashing car horrible to drive, the steering and the braking was compromised and the noise that started to appear about 3 months after the beeping first appeared was horrific from the wheel bearing. I am not sure if this is the case in ur car but that stability control issue was the beginning for me..... after a series of mechanic trips resetting the computer etc and purchasing new tyres....

The wheel speed sensor reads off the face of the wheel bearing. The issue is debris gets stuck to the bearing and messes with the signal. The fix is to clean the face of the bearing but the problem is the axle and bearing connection is so tight that sometimes when you remove the axle the bearing comes apart and has to be replaced.

I had an issue like this, ESP turned off - engine light on - contact service aganet.....blah blah blah.. Did the right thing took it straight in====well......8 hours $80 later tech2 says"transmission fault"
Horse shit!!! Took it home and did a once over everything. Plugs/leads nope! ECU plugs...water....nope! air intake.... YEP someone had screwed up the rubber lip seal around the airbox/intake hose[ pull apart/reseal]
To test it disconnect the sensor plug just left of airbox - esp lights up!! plug it in esp off!! intermittant is the air pressure differences when it seal/unseals.
Hope this helps.
Just to vent "bullshit, horse shit........transmission fault???" feel much better nowstupid service centre.
