Is there a way to delete the abs module on a 06 ss. I am working on the swap into the cavalier and found out that i need that plugged in to turn over. I do not need the abs system and would like to delete it. Or if anyone has a pinout on this harness that would help too

 

Absolutely ABS can be deleted.

What you mean by "i need that plugged in to turn over"??

 

I need to have the abs module.plugged in for the car to turn over. When it is not there is no power going to the starter when i try to turn it over

 

Oh i get it. Give me the year of the donor car and i'll tell you how to bypass it.

 

2006 ss

 

On the ABS Module connector find the following wires.

Pin 21 = Tan/Black
Pin 22 = Tan
Pin 36 = Tan/Black
Pin 37 = Tan


Run the Tan to Tan
Run the Tan/Black to Tan/Black.

That should do it.

 

Report back if this doesn't work.

 

I will give it a shot tomorrow thanks

 

If this works make sure you connect them real good and insulate them. They're the GMLAN wires that carry data between modules. If this daisy chained circuit breaks, shorts etc the car will not run or will do all kinds of weird crap.

 

Update?

 

This works. I have the same exact car and have done it. There is a lost communication w/ABS module DTC that results. It can be turned off using HPTuners or similar.

Contrary to popular belief, any module can be eliminated.

 

The only one that I can think of that can't be eliminated easily would be the one that reads the chip in the key, whatever that one's called.

I do not believe this PCM can have the anti theft features deleted via HPT. If it can I am very interested in knowing where that can be found.

The reason I believe bridging the wires together will enable his engine to start is because the security module is not integrated in the PCM and it uses the GMLAN *which is daisy chained* to give the green light for starting to the PCM and with the ABS unplugged this chain is broken.

Please feel free to chime in and correct this post if I am wrong on this one.

Thanks.

EDIT: Sorry poster above, I re-read and this time understood what you were saying about HPT and yes, the communication code can be disabled in HPT. For some reason I initially read your statement as saying that the anti theft could be disabled in HPT.

 

Vats can be disabled. I've disabled mine.

And I know bridging the lan works because, like I said, I did mine that exact way.

But I'm not sure exactly what you are calling "anti theft" so I'll wait for further explanation there ...

 

OK, it's been a LONG time since I did all this research which is why I had to think back and recall it all last night before I could post this.

The OP didn't state what SS he had. There was a 2.0 Supercharged (LSJ) SS and a 2.4 naturally aspirated (LE5) SS in 2006. Mine is a 2.4 NA SS. Your repeated reference to a PCM is what made me think about this.

I'm not sure what model PCM the LSJ used. (Is it the P12?) But the LE5 in 2006 did not use the same PCM. In fact, it didn't use a PCM at all, it used the E67 ECM with the T42 TCM.

Whatever the LSJ used I am 100% certain that HPT can not disable VATS on it. I think this has more to do with the amount of energy HPT as a company put into hacking the PCM. They didn't see it as a huge mover for their product so they didn't go as far as to bother hacking the security system.

BUT the E67 ECM is an EXTREMELY popular ECM. It is used in LS2 and LS3 V8 applications which are what HPT devotes the vast majority of their energy and resources to. Thus, people like me that are using the E67 enjoy the benefit of all that research and effort on engines other than V8's. One of the things that we enjoy over the LSJ PCM's is the ability to disable VATS. (We also enjoy more traditional injector tables designed just like the V8 tables, no interpolation required to convert V8 numbers to P12 numbers.)

In my LE5 application the BCM is what reads the chipped key. It is also the termination point for the LAN. So when eliminating it I have to terminate the LAN at whatever the last control module is on my network. (In my case that will be the TCM.)

This next statement I am only 75% certain of because once I got my LE5 I stopped researching the other applications. But if you are using the LSJ you will not be able to disable VATS and therefore will need the BCM somewhere in the system to read the chipped key. I do believe that it should still be possible to delete the ABS module as described though.

If the OP is using the E67 then I can say with 100% certainty that deleting the ABS module as described above works and the resultant DTC can be deleted because I have done it on mine.

I'm sorry if I confused anyone with my original statement.

 

the op is doing an lsj turbo swap into a cavalier. he has a thread going in the lsj section.

the lsj uses the p12 pcm. kinda sucks that its only half unlocked. but as far as i know it was only used with the lsj and the atlas engines (2.8, 3.5, 3.7 and 4.2l in colorado, canyon and trailblazer/envoy).

as far as disabling the vats, i dont think it can be done. i did just have a look and under the system tab there is a tab for vats control, enable or disable. dont know if that would disable it or not.

 

That's the part I was missing.

Just for my own future knowledge, what PCM / ECM does the LNF use?

 

If the disable VATS option is there it should be possible. I am reading that VATS on the LSJ CAN be disabled. I think everything I was thinking for the LSJ actually applies to the LNF as I am also reading that LNF VATS can not be disabled.

 

LNF uses some Bosch oddball PCM and it most definitely cannot have passkey disabled in it.

The LNF actually has a separate module that reads the key and sends the go ahead to start signal to the PCM.

The tables that HPT has opened on this PCM are pretty much the bare minimum to do some tuning on it.

Very few tables to work with.

 

Side note: I love it when a poster comes in, asks questions then doesn't bother to update the results.

Real pet peeve of mine.

Makes me less and less motivated to offer advise.

I would assume it worked for them because otherwise they'd be back in here asking more questions I bet.

 

I am sorry i have not posted an update i have not had a chance to try it. I have had no time to work on the car. I do have some other issues that i will be trying to work on tomorrow and once those are solved i will be bypassing the abs. For some reason i am getting a p0230 code for the fuel pump circuit. Fuel pump will not prime and i know i have no spark. Hopefully this will be cured tomorrow. Anyone have any ideas?
