Is my 94VR ute OBD2 as I can not get the vehicle to respond?
Did some research and my OBD's won't work as my cig lighter plug circuit has no power. Is this right?
vr-vs is aldl not obd, you need an aldl cable to read the ecu
Then my scan tool won't work either is that right? I have an OBD scan tool. It plugged in no worries and booted up, just wouldn't communicate.
what scan tool do you have? aldl is OBD1 most of the cheap scan tools/dongles are OBD2....
It's supposed the be both. It wasn't expensive around 100-120 bucks. It worked fine on Jeep but that was OBD 2.
what's EOBD? Maybe it doesn't read OBD 1
Don't think mine does OBD1. I thought my VR might have been OBD2 since the plug is the same. Should have realised not, since AFAIK OBD2 came in around late 95 early 96. Although sounds like Commodores started using OBD2 later than most.
AFAIK LS1 cars are OBD2 as are alloytech and above I think...anything with a ecotech in it would be aldl/OBD1 well my missus VX is
I use Envyous Customs software so much easier for diagnostics and just plan works
or just use the paper clip method
yeah I was thinking the paper clip method will have to do. No need to buy a OBD1 tool.
OBD2 was not introduced until VT.
Up to VS is "ALDL" which stands for "Assembly Line Diagnostics Link" It is a totally different GM System.
All these cheap Asian Scan tools will NOT read up to VS. You'll need a Tech1 which are rare as hens teeth using the VR or VS cartridge. Even most of the Holden Dealers no longer have those as their employees knocked them off to either use themselves or sell on eBay as they fetch huge money now.
Sadly we are now only left with the bridge terminals 5 & 6 method using a paper clip or short made up piece of wire in a U shape.
I had it scanned once before but that was at KTAS and he used a Snap-on scan tool. Something I won't be buying in my lifetime unless I find one at a garage sale and the person doesn't know what it's worth..
You can buy the software and cable(link in my last post) if you have a laptop laying around...a small eee pc laptop can be had for 100$ or so(just make sure it meets min requirements of the software you want to use) ...Cant stress how valuable it is as a diagnostic tool, has saved me hundreds of dollars rather than playing the suck it and see game......
I will keep it in mind Wozza as an option. Reckon it's something I can look at next year once I have finished building the house and wedding is all paid for. I'm overdue for a new lappy as mine is nearly had-it. Ute should be ok for a bit now hopefully.... famous last words, as I have just replaced what I'm 98% sure was a faulty TPS.
