VE V6 VCM 'time out at location 0'

[Gareth]

As per the title, im having trouble reading entire from a VE V6. Im using HPT, I have removed the SIR (airbag) fuse in an attempt to unclutter the data line (when doing a factory reflash this must be done) Battery voltage is spot on 12.8V and laptop is plugged in. I have searched high and low on the HPT forum with no luck.



Has anyone had this before?

Cheers.

I had this issue on older verisons of HPT, it wouldn't read '08 and newer E77 ECMs I think it needed something slightly different to initiate a download. Apparently this is fixed in later version.

It looks like an incompatabilty between hpts bootloader code and the pcm. I dont know for sure that that pcm needs a bootloader so i cant say for sure but the preparing stage is where it would upload one (and that succeeds) and hpts software takes over the pcm but if it fails to run on it then it wont start transmitting the bin back. I reckon thats one for hpt support and they might change or fix their code for that osid on that pcm. I doubt bus traffic is the problem because can is pretty good at avoiding collisions (all obs2 protocols are) and even then it would still work, just slowly.

You could try disabling high speed, maybe it'll make the bootloader code function differently and you might fluke finding a work around for the problem.

Edit: just saw ejukateds post. Sounds like they have fixed it. Time to update!

And this is why I think this site should have a donate button...

out of interest, what version where you on that didn't work ?

[Gareth]

didn't pay much attention, 2.24??? haven't ever updated since I purchased it about 5 years ago

[Holden202T]

lol that would explain it

I know I have done some tweaks for a mate on a VE V6 and it just worked but I generally try to update to the latest version when I get the update emails.

It was somewhere in the late 2.24 versions they fixed it.

The E77 doesn't use a custom bootloader it's all controlled by the ECU. Their code is the reason it takes so long to read, hardware etc. is all up to it.

yeah I recall the VZ Alloytec V6 pcm took 15-20 minutes to get the original bin file from it!
