Tech 2 Purchase

[TJ Baker]

I received my Tech2 from chinacardiags a couple a weeks ago. I noticed the DLC cable connector would not completely seat into the VCI connector. The cable connector has a molded boss that locks the VCI latching lever. I had to trim the boss on cable connector to clear the VCI latch.

Silver marker highlights trimmed corner on boss.

Mine did talk at first. Heeding advice from others I didn’t unplug it at all. I used the AC power supply with the pigtail plugged into the inline jack. The only two things which got unplugged were the power supply from the extension cord and the candi from the OBD. Then it stopped talking to candi one time. And hasn’t since.

live looked for bent pins and flash in the connections. I even bought another cable from the tech 2 to candi. No joy.

I’m thinking I may chop the end off a cable and hardwire the damn thing to candi, to eliminate that point. Which would still leave the VCI port, the OBD port and candi itself and possible failures.

That sounds like a really good idea.

By the time I would get done dicking around with playing musical parts. (assuming I buy them) I way as well pick up a VXDIAG for $100.00

I bought the handheld because I liked it better than using a laptop.

I've heard that getting that setup can be a pain and take some time doing.

I had one and managed to get it setup without too much difficulty. It had a bad cable but I had a cable that would work. I struggled to connect it to our Envoy because I selected the wrong body style. Not realizing my mistake I returned it and bought the handheld.

Have all these units that are having problems been purchased recently? Maybe there was a batch of faulty parts used, or production QC problems due to covid or something.

I bought mine about 2 years ago and keep it with all cables unplugged and plug them in whenever I use it and have had no real problems.

Only thing I've noticed on mine is the connectors are super tight and I can't get them to actually "latch" together. That little metal latch gets about a mm from actually clipping into its slot. When I first got it and noticed this I used dielectric grease on all the connectors/pins to help make it easier to assemble the cables

So I just tried ringing out my DLC cable to 16 Pin OBD2. Glad that I don't have any Canbus vehicles or this would have given me fits. 2 pins of the 16 on the OBD2 end have lousy connections through the 19 pin Burndy on the DLC cable. #12 & #14, #14 being absolutely needed for Canbus. Tried cleaning with electrical cleaner, removed the faceplate of the Burndy and removed the damned spring even and still no go. Would never trust that for programmimg.

EDIT: I wrote this wrong below, the defective part is the adapter, not the cable.

I think the defect is the DLC cable portion, on close inspection there are two areas crimped in a little to grab the inserted pin(s). The two I have issue with don't appear to be crimped deep enough to make good contact with the pin(s). The result is intermittent connections...

I have an update... I looked a little closer and discovered it is not a crimp but there are 2 wire like clips in there. With a flexible backprobe needle I am able to poke behind the clips making them tighter. It may "fix" this....

Got a better PIC of the "pins"

This what I have right now. About to retest. Getting that spring out is difficult, I 'screwed" it out with needle nosed pliers. I like it much better without the spring but it did not help the poor connections.
