Tech 2 Purchase

That’s all under diagnostics.

Yeah, it kept giving me that error message. Do you need the candi module to do that? I tried with and without it.

I don't think you need the Candi modual with an '05.

That said, having the Candi modual on if it's not needed shouldn't matter. If the vehicle doesn't need it, it won't use it.

Yeah, I tried both ways but really couldn't do much.

Did you just get this? Make sure all the connections are plugged in good (bottom of unit, input of Candi, and OBD adapter). Also try seating the PCMCIA card into the other slot in the top of the unit.

Otherwise, it may just be a bad/defective unit

Says in the GM User Manual the Tech2 updates the software in the Candi when it's attached if it needs to. That could that be what you are seeing in your pics Tony.

I would start by removing the CANdi module and trying it. If you need that module for your 05 which I don’t think you do, it looks like it’s trying to update it like David said which can only be done if it’s connected to a PC and you’ll have to figure out how to do that. Which software version was this Tech2 supposed to come with?

I did, bought it used, but at a reduced price because the guy wasn't sure it was 100% working correctly. Pretty honest. I'll try swapping the card around. Everything is snuggly plugged in, I triple checked that.

I have no clue what I'm look at lol. I haven't connected it to any pc yet.

I've plugged into the obd with and without the candi module attached. Got the same error message both ways. It has the newest version--33.004. Do I really need to connect it for an update? All I want to do is use it to diagnose.

Iirc, pretty sure I did do that. DAMN! I wish these things came with a user manual! I'll mess with it tomorrow, gonna be raining all day today.
How would you get it to do tests--like beep the horn, needle sweep on the cluster, trans solenoids etc? This is a great tool once it's figured out--or I should say once I figure it out!

It is like any other electronic device you purchase, Your ability to use it is anticipated and mandatory, The tech dweebs that design it cant percieve you not knowing exactly how to fix your problem right now and probably take joy in your frustration! But dont worry right now one of them is trying to figure out which button to push to cross the street and why the crossing display dosent resemble them so it must not be their turn yet!

eBay? Are you still within the return period?

You said you got engine codes out of it. I got nothing from my bad one

Power it up using ONLY the AC adapter. No data cables. It should go through the POST (Power On Self Test) and tell you if it passed. If it doesn't pass the POST, it's defective.

EDIT: should look like this after POST, and make sure your software version is this one:
