Can clear airbag codes without a tech2

[SturdyHSV]

Free software and about £10 worth of cable =)

VZClusterMod is the software, done by the yanks over on ls1gto. This also does the logo changes etc and a selection of other fanciful bits, but I've only done the airbag clear.

It should read the codes too, but I'm not if they've found them all.

Will post eBay links to cable bits when at a pic, bit messy on the phone.

You'll need a USB to TTL (NOT RS232) cable. TTL is like RS232 but at 3.3v instead of 5v. You'll want an FTDI chip if possible, easiest way to guarantee compatibility.

I got this one for £9.99

You could jam the pins in, or go tidy and buy a male OBD2 connector (bit of a rip off but meh...)

You need to solder the ground (normally black) to pin 5, and the TX and RX both to pin 9 (normally white and green).

Good news.

Why did the yanks see the need to do this. There must be issues with the VZ BCM???

I would like to try this so if you are buying any of the stuff, can you double up for me??

Isn't this the same as ferret used?

Ah crap sorry Gareth, it all arrived yesterday, I didn't want to post up until I'd done it and knew it worked!

The cable is going to live in the car, so at any meets you're welcome to have it, alternatively yeah it's all 'fast & free' postage on eBay so group buy possibly not worth the effort!

The yanks started off down the programming the cluster route, so start up logo and shift light, and naturally as they've learnt more of what the tables in the cluster mean, the airbag functionality has appeared as well. Reprogramming the coolant gauge is the coolest bit for me, I'm just dumping my MAF at the moment so haven't driven the car yet to test it out, but should be a lot more useful than the stock set-up, whereby 3/8 accounts for any temperature between 80 and 110!

It's the same process, but his was a little more complicated. He was doing it at a similar time to the yanks so very much early days, the yank software has been developed a bit further now, so is simpler.

Cable wise I think ferret got a proper cable too to know that it would work

There's naturally a bit of a risk as there's some differences between the two clusters (they don't have the Vauxhall option at all) but given that the airbag system has been the same since the VT just with extra bags added on, it seemed fairly safe to give it a go!

Ok cheers, handy to know

Excellent, I'm off to CPC on my way home

Hopefully it's up to the job :-

That looks like it should work, may be worth trying to verify if it's an FTDI chip in there, but they seem to be the most common so it probably is.

Let me know if there's any other info you need

[alfienoakes]

Cheers

Having read further I don't think that one has the correct chip, but this one should have :-

It's dearer but I've got a £5 voucher which is about to expire soon, so I've justified it to myself !

My ebay one is cheaper, but understand if you want it tonight

You beautiful bd, help me make my coolant gauge behave

Their program works on the 04 cars, so I think you should be fine?

Mash a cable together, try the software and see if it listens and can read the tables etc.

You (or we) can then compare the contents to the yank stuff and verify that it shouldn't break anything (or just go for it )

To elaborate, there are 10 'tables' in the cluster. You can read / write them with their software. As such, easy enough to read them back, verify the contents, make any changes, write it back etc.

The coolant gauge will work the same way over here to the US I'd imagine (cannot see why not) so should be fairly simple to update the table without borking anything

[KMud]

Sounds good...I have spare vy and gto clusters if it helps any...but sounds like minimal risk of bricking.

I couldn't get it to recognise the heartbeat

My windows 7 driver doesn't have the option to connect at 8192, I'll try it on XP tonight...

[KMud]

I've ordered the bits. Do you still get the heartbeat stuff if you have the cluster on a bench? I'm too busy to read up on this right now, will get less lazy later

I didn't have to do anything with baud rate settings, presumed the program did that for me. If it's not an FTDI chip, it may not have the 8192 option, or as you suggested it may be that it's got a driver that doesn't allow it.

This driver should do the trick apparently:

Did you try running 'listen' to see if it saw anything coming from the car?

If you get any 'fuel gauge error' or 'contact dealer' messages whilst the cable is plugged in, it's the wrong cable

You don't, but you can just put in 'bench' and it'll run it in bench mode whereby it won't expect the heartbeat.

Good to know, ta. For what it's worth, I guess I'd do my proper cluster in-car...and there's not much point in doing the other ones.

Well done James!

still no luck
