Now that's an interesting perspective. I don't think anyone here has looked at it quite like that.Matthew_S said:That code could have been in there for years. I've scanned at least three or four VW or Audi SRS controllers that had the low voltage code with no light on. It is the only air bag code I've ever seen in any air bag controller that didn't turn the light on.
I was unaware that that cde could exist without setting of a caution light.
I do not think any of this can be settled without checking the power and ground at the controller. I can use the volt meter in parallel and use the connector's power AND grond at the same time to test the circuit without using the OHM meter's injected current, eliminating the risk of the ohm meter blasting the bags. I just need some wiring diagrams and figure out how to get to the controller.
As for all of the statements comparing the vag-com tool to a craftsman wrench or the genuine VW tool:
I agree that we're flogging a dead horse.
My contention is not that it would not have happened with a VW tablet but that it did happen with vag-com. certainly, it's apparently well known that the issue does, ineed lie inside the VW part. Furthermore, my contention is that the Vag-Com people know about the POTENTIAL to cause damage, at one time had a failsafe that disallowed a user from scanning the airbags by default-thereby limiting the potential, and then removed that failsafe in the 607 version.
I believe that vag-com et-al should, as soon as possible, issue an updated version of their product which reinstalls that failsafe, thereby protecting their customers.
I feel that it is totally irrelevant wehter or not there is or is not a voltage problem in the car. The fact remains that there is a "bug" out there, scanning the controler with vag-com and others "awakes" that bug and fries the controller via the 65xxx dtc.
The fact remains, and I stand firm on this, that had the 607 version which I used, had a failsafe in the form of a dialog box with red letters saying "you are about to do possible damage your ABS system, do you wish to continue?" I would have clicked cancel and this thread would never have existed. The controler may, hopefully, have thrown the low voltage code, which I would then have to deal with, but I wouldn't be buying a controller.
It is the absolute resistance to this protection of present and future customers that amazes me.
I sincerely hope that vag-com will issue an updated version with an ABS failsafe. However, at this point, I think we all should agree to disagree.
If anyone has any tech info that might b useful in verifying the low voltage code, I'm all ears.
