Thank You Josh for all Your help keeping Our Holdens roadworthy. This is Paul with Scottdale with a 2006 silver GTO automatic since new. My latest dash board issue just started last month. The entire red assembly goes dead and comes back on when driving the car. The car still drives OK. I was able to get a brand new dash assembly but maybe I have a bad ground... I will check what You said to look at... Thank You again for helping Us try to keep the Holdens on the road🌞🏜
Better have the codes to link the modules together if any one of them fail. Make sure if you are flashing the ECU, PIM etc, use a flash programming power supply or you can brick the ECU and other modules. Ask me how I know.
@@JoshsCarCorner Yeah, the E40 ECUs are harder to find for the 05 GTO and more expensive. Not too sure if the architecture inside any other ECU will work. I heard even the 06 is slightly different from the 05 and probably wouldn't work calibration wise.
As far as the BCM wire rub issue being resolved in the 06 cars, I'd say that's not true. I got my 06 in 2010 and the tape was rubbed through and the brace was just starting to wear on the wire insulation. I wrapped it in a piece of heater hose and I've not yet had any electrical problems. One interesting thing I found with my 06 and using a Tech2: My car has the Holden/GM gauge pod on the top center of the dash. Any functions of the Tech2 which require the CANdi module to be connected to function will NOT function while the dash top gauges are connected to the car. Disconnect the gauge wiring at the gauges and the Tech2 with CANdi work just fine. The CANdi is not required for all Tech2 functions but it is required for a lot of the more complex functions. I almost replaced a perfectly functioning CANdi module before I figured this out!
That's a great bit of info! Must have something to do with with needing an open Class II serial channel for the CANdi, and the center gauges must be occupying it.
I discovered this interesting bit when I bought my 04 last year and plugged in the Tech2 just because and everything worked. Which made me even more confused as to why it didn't always work on the 06. Then someone on LS1GTO mentioned that the dash top gauges might need to be disconnected and I tried it and then the Tech2 worked fully! I guess it kind of makes sense but I would have never thought to try that on my own.
Hey I'm build a 04 gto that will achieve 200 mph . I had an 06 that I was going to do it it but I wrecked it. So I bought an 04 body and I'm changing everything over . I built a iron block 6.0 . Had the rotating assembly balanced PRC 243 CnC heads. With long tube headers Now I'm upgrading the suspension . Ill keep u posted and I'll video it when I do it.
i want racing seats but afraid of the airbag fault. Ive research and people say disconnect the battery and remove the yellow and plug it up with the el 46841 part. Will this still throw a airbag code even if i plug it up before i re connect the battery.
It can only be removed by taking the firewall out of the car. Otherwise you have to cut the firewall or completely disassemble the fuse block and put it back together.
Josh once again doing a major solid for the GTO community...
Excellent video Josh, especially your mock setup of how the different modules are connected
Outstanding video, I never noticed that ground connection behind the battery. Great walkthrough of the network diagram.

@pjcornell Did you find the problem? I have the same gremlin. Thanks.
Awesome video. Especially for us gto owners who want to keep ours for a long time.
oh man i´ve been wanting GTO so bad, finding your channel is so good
Awesome. Thanks for taking the time. I am currently trying to undo a bunch of what I call "kid mods" done in a hap hazzard way and this is a big help.
Thank you for all this info. Good stuff 👍
Fantastic vid! Thanks for this!
Great info and great video!

Yeah I already knew. It's called Project E38.

Best video i seen thanks heaps
Very informative video thanks

Can you elaborate on the AUX gauge please? I'm wanting to work on a GTO project and looking for all the info I can
It refers to the optional center console pod gauges. One is battery voltage, the other is oil pressure.
@@JoshsCarCorner are these available anywhere and how would I search for them?
Any one have there horn honk when the car hits operating temp? Or ONLY the left brake light staying on
how is the wiring harness removed where it goes thru the firewall?
It can only be removed by taking the firewall out of the car. Otherwise you have to cut the firewall or completely disassemble the fuse block and put it back together.
What about the cluster flickering in and out?
That's electrical issues, can't fix that with programming
Is it hard to get for interface control module?
The PIM? It's not hard to get one, programming it is hard. You need a Tech2 to do it.
I have a 2005 pontiac gto with a major electric issue help me out im in California 😢
Email me at ccrtechwi@gmail.com
I got a no crank no start,my theft deterrent won't turn off.
My horn and wipers don't work.
You should delete the bcm and document it. I saw one guy on a forum page did but won’t do a write up
I would never. It controls too much stuff that I'm not willing to lose.
First
If only i didnt have to buy a car battery every 2 years
A simple battery tender is $60. My GTO's battery is 4 years old and still cranks like a champ.
