Had the hoe towed home!!

[2011SSVHOE]

2011 hoe 5.3 4wd, lost power, CEL and service stabiitrac, service traction control lights came on. dic also said reduced engine power, no shit as I sat on the side of the road. I noticed it also had a rough idle. Called triple AAA for a tow. walked up to the store for some beer, and when I got back started her up and everything seemed ok but the CEL was and is still lit up, at least he was able to drive it on the flat bed. I'm gonna have to go buy a scanner. any one got any ideas !!!!

ps the tow truck driver said he had just towed a chevy truck for the same problem

TAC module?

Not being a dick or captain obvious but what about ur batt and grounds and crap like that? Hit a big pothole or bump or something?

 

[2011SSVHOE]

no no potholes and not to sound too stupid wtf is the Tac module I guess I could go on you tube to find that one !!!

 

[2011SSVHOE]

sorry I just googled TAC module yep that may need to be checked Kinda stressed right now. I think i'm gonna bite for a Tech2 scanner. It'l be cheaper than going to the Stealership and when i'm done i'll have a nice tool instead of a receipt that say thank you very much we appreciate your business, aka wallet cleansing !!!!!

TAC = Throttle Actuator Control. It's the module that interfaces the throttle pedal input with the DBW TB (Drive-by-Wire Throttle Body, which uses a servo motor to actuate the throttle blade as opposed to mechanical linkages and a cable). There are other parts involve in the system such as the throttle body itself and the APP (Accelerator Pedal Position) sensor. The problem may not be the TAC module itself. It could be any of the related components of the system. Getting the code(s) read is your first line of diagnosing.

There's a thread here about a Tech II clone that seems to be getting rave reviews and it's a fraction of the cost. Had I been better informed, I would've bought one instead of dropping nearly the same amount on a nice, but far less-capable diagnotics tool.

Previous shop I was at bought one of the Chinese tech2 clones. Was a waste of money still. All you could do with it was read codes/data on a gm vehicle only. Was a big paperweight.

I thought the Tech2 was a GM-only tool, anyway

As in you couldn't modify anything. Just a gm specific scan tool was all it did, and harder to use. That's all. We could do way more stuff with our otc encore and bosh j2534 setup on everything we bought credits for.

Edit: the Chinese tech2 was like buying a universal $25 harbor freight one for more money and only read the codes. Couldn't clear them either.

You SHOULD be able to do "way more stuff" with a $1500+ scan tool, which is what a shop needs. The idea with the knock-off TechII is to do the same or nearly the same stuff (with GM vehicles) for a few hundred bucks. Sure, this may be limited to GM only, but that's fine in this situation because the OP was talking about a scan tool for his Tahoe. Sounds like there was something wrong the one your shop received.

No your not understanding the way I meant it. I understand the tech2 is a gm only tool. Just stating that for the money they paid for the clone it was no better than a 25 dollar generic scanner that only works on gm. It does nothing but read the codes and data. No output controls, no ability to clear codes, no access to bcm or other systems. Just saying as a factor of buyer beware on the clones.

I'm on the fence I see what you are saying , if I get the tech 2 or buy a decent scan tool and maybe later get a range AFM delete and later a black bear tune and on and on If the tech 2 works I can do so much more. Oh and by the way I only have GM vehicles in my family

After some quick researching, I'll have to retract my suggestion about the Tech2. Apparently, it won't work on anything past 2009 and an MDI is needed.

I'm understanding your post as a warning to the OP that some clones may be defective and no better than a $25 Harbor Freight scanner. Either your shop got a defective one that would only do limited one-way actions, didn't know how to use it or they tried it on a 2009-2010+ vehicle. The clone is supposed to everything the real ones do as attested by at least one member on this site (fiatdale). What muddied up the water is when you compared an apparently defective clone your shop has/had to $1,500+ legitimate scan tools that also work with other manufacturers.



Roger, I apologize for the confusion. Basically, if you want 2-way capabilities, you're gonna have to shell out big bucks. Apparently, there is an MDI clone, but we'll leave that out of this thread. There is a bevy of one-way scan tools if you wanna get something to just access data and clear codes. How much info you wanna be able to access from however many modules will determine what scan tool you get. Do your research and choose wisely. I have an Autel MD802 and it reads everything on my Tahoe I've tested it against. Supposedly, it'll perform all possible one-way functions. I got it for $205 on eBay from authorized distributor- unauthorized distributors have them less, but service after the sale is likely non-existent.

Thanks for now I m going to borrow a scan tool from autozone need to get the truck back on the road

 

[2011SSVHOE]

just got home Its code P0068 something to do with the MAF sensor, now the fun starts

 

[2011SSVHOE]

Update , I cleaned the throttle body and MAF sensor , reset the codes, drove it around the block and everything is ok,

So now what , no check engine light no codes and will it fail again soon?

 

[2011SSVHOE]

I thought the Tech2 was a GM-only tool, anyway

it is and that's why I would want one and yes it's a clone

 

[PG01]

Well, at least its running now, right?
