VATS Removal help

[quasi_71]

Hi guys, complete newbie here. What I'm trying to find out is what I need hardware and software wise to read my eprom, disable VATS and pump it back in. Currently playing with a VT Clubsport with LS1. I've been reading through this forum and just getting more and more bamboozled so any help would be greatly appreciated

Being clubsport it adds more into it...
There could be hsv wiring updates that will make it harder...possibly!

You need to have software & hardware to disable vats & then check for responses!

If it hasn't worked then need to start looking around for suitable tuner/eltronic specialist workshops!

I know there’s a few people on here that could help turn vats off. Have a look in the tool section I think it is. Sv5000 made some stuff that sells on eBay for like $500 and I think antus is going to do further work on his ls1 stuff. If your just wanting vats removed it’ll be cheaper to get someone else to do it.

Thanks guys, I'll get someone to do it for me. I am still interested in tinkering but if there's no cheap DIY solutions then I'll leave it at that.

As alluded to above, just remember being a HSV it will have the Embedded Security System (ESS) fitted by HSV as standard.
If this is what is causing you problems a VATS delete will not help.

ummmm is ESS removable just like VATS ? Or is that not in the ECU?

[yoda69]

Hardwired into the wiring harness up in centre of dash, designed to be near impossible to get to without removing the dash.

What models was this ess on? I reflashed my vy clubsport with vats off and no dramas.

Code: Select all

From Holden Techline

There have been three different types of security systems fitted to HSV vehicles in addition to the standard Holden security.

1. Imbedded Security System (ISS) – Non passive: Fitted to VS Series 2 vehicles.
Has three barrel shaped keys (two black and one red) which can be plunged into the key pad in the centre console. The black barrel key needs to be plunged on every start up. The red barrel key is used to introduce replacement or additional black barrel keys to the ISS.

2. Imbedded Security System (ISS) – Passive: Fitted to VS Series 3 and VT Series 1 vehicles.
Has three barrel shaped keys (two black and one red) which can be plunged into the key pad in the glove box. This system does not require the black barrel key to be plunged on start up. The red key is used for introducing new ignition keys or additional black barrel keys to the ISS. If no red barrel keys are available to introduce new ignition keys then the black barrel key will need to be used every time the vehicle is started. If neither red nor black barrel keys are available the complete ISS system will need to be replaced. ISS red keys are not available separately as they are individually coded to their modules and can only be purchased as part of a complete ISS kit. Therefore if an owner needs a new ignition key but cannot provide the red barrel key the only option can be to remove and replace the ISS system. Dealers should try to ensure that when trading in or selling any of the above vehicles the ISS keys are passed on with the vehicle to save your customers and Service Departments inconvenience.

3. Embedded Security System (ESS) – Passive: Fitted to VT Series 2 to VZ vehicles.
Is a totally passive system requiring no owner input or extra keys. All diagnosis for ESS systems can be accessed on Holden SIP under HSV Models Section J Options and Accessories. When linking new keys to an old BCM or vice versa, a link enable procedure will be required. The link enable procedure is generated by Australian Arrow and their phone number is available at the end of the ESS diagnostic procedure in Holden SIP.


HSV EMBEDDED SECURITY SYSTEM
The HSV Embedded Security System (ESS) is a micro-processor controlled immobiliser which automatically interrupts four essential electrical circuits when in armed mode, preventing the vehicle from starting. The ESS stores important security codes and every time the vehicle is started it reads these codes. If any of these codes are different from the stored codes the ESS emits five beeps, enters armed mode, and prevents the vehicle from starting. If the ESS receives the correct codes it emits a single beep and allows the vehicle to start.

Operation of the ESS requires no extra input from the owner above the normal procedure of starting the vehicle. When ignition is switched off the module automatically enters armed mode. Disarming the system is achieved simply by inserting a correct key into the ignition barrel and turning it to the on position. Confirmation of the disarm is provided by a single beep. Conversely, if the vehicle enters armed mode when the ignition is turned on five beeps are emitted.

The ESS has been designed so that in the event of power loss to the system (flat battery or theft attempt) it will return to the same operating state when power is restored. For example, if the system is operating in armed mode when the power is interrupted, it will return to the armed condition when power is restored.

To further enhance vehicular security the module is placed in a difficult to access location and is embedded into the vehicles main wiring harness. All wiring to the module is the same colour and of the same wire gauge.

A Security Information Card is supplied with the vehicle which contains the ESS PIN. This PIN is required by the authorised service agent in the event of either a Body Control Module (BCM) replacement or if new keys need to be programmed to the vehicle. The service agent contacts Australian Arrow Pty Ltd quoting this PIN. They then get the PIN converted to a particular security code which corresponds to a sequence of vehicular functions. By performing this sequence, which is different for every vehicle, the vehicle can be fitted with a new BCM or have new keys programmed to it. There are approximately 60,000 different codes available.

The HSV ESS is an electronic immobiliser which derives its main power feed from the car battery. However, the current consumption when the ignition is turned off is zero so there will be no adverse effects to your car battery.

Ok. So did I just get lucky? I remove the ls1 ecu’s and reflash them on the bench not sure if that makes a difference. The only only issues I’ve had since the mafless reflash was on first start up where idle needed to self learn. I’ve also reflashed my brothers wh with has all the hsv upgrades and same thing no dramas. I was surprised when I uploaded the tune off his as it was the os as a vy
