I got it done on my 2012 Volt. You need to have it done within your b2b warranty period, otherwise it will cost $$$.Yes, it has been mentioned that the dealer can enable it for you. I would love to get it. I have no idea what they would charge me for it, but I am sure it would be too much. I wish there were a DIY way to activate without buying a multi-hundred dollar tool.
I think literally, all it does is blow the fans (no heat/AC) on high for a few minutes. I've heard it activate a couple of times during hot summer days. So it won't use much energy at all.^ good tip. That time is over for me, but it might help many others. If you live in a humid area, I think it is well worth it. A/C funk is common, and possibly more so on a car that runs the AC to cool the battery even when you may have it turned off for cabin cooling purposes.
Nice find! I'll have to bug my dealer about the afterblow update next time I go to get my tires rotated.
WOT posted the relevant GM service bulletin #99-01-39-004 regarding Afterblow setting several years back.
AFAIK: Enabling/Disabling Afterblow seems to be the only configurable GDS2 'setting' accessible that remains held in memory/NVRAM after disconnecting GDS2 or even removing 12V AGM battery power.
Having this enabled on my Gen1, the blower seems to engage for @30Sec at a much lowered speed (not running 100%) occuring after about 10min of the Volt being off. It does repeat this @30sec ON then 10min OFF duty cycle for about 5 iterations before ending.
My experience is having afterblow enabled or disabled has no noticeable corresponding effect on the remaining battery charge level of my Gen1 after being driven then parked for several hours while not plugged in and charging.
BTW: Quick glance in GDS2 shows afterblow setting is not only avail for both Gen1 & Gen2 Volts but the 2017 Bolt as well!
Any recommendations on a specific Bluetooth adapter or which type of generic ones to get?afterblow turn on or off app for andriod uses obdlink mx bluetooth adapter I will update to support generic adapters soonhttps://play.google.com/store/apps/details?id=com.myvoltapp.MyVoltAfterblow
Brian, thank you so much for this! I tried to install the app on my Samsung Galaxy Tab 2 tablet, but it wouldn't even let me download it. It said incompatible with your device. Any idea why? It's the same tablet I use with MyGreenVolt and Torque with no problems. I ended up borrowing a friend's Android phone and using your app on that. It worked great!afterblow turn on or off app for andriod uses obdlink mx bluetooth adapter I will update to support generic adapters soonhttps://play.google.com/store/apps/details?id=com.myvoltapp.MyVoltAfterblow
