Where do you connect the cable?
Take 2006 Land Cruiser for example, Techstream (~ Hand Held Tester) connects via your OBDII port in the footwell, Toyota/Lexus call it DLC3 – Data Link Connector – and DLC1 is the connector under the hood. It provides easier access (for me at least) to the main players for AHC diagnostics which are the Ts, Tc and E1 ports. Regardless, Tc and Ts are connected in parallel.
It’s worth noting that there is some erroneous info for the DLC3 terminal pin outs. I have Toyota EWDs and Diagnostics pages that represent terminal Ts as on pin 12 or pin 14 – this makes a big difference to your fault finding efforts! If you’re going to use DLC3 it’s worth physically verifying your connections and validating your data. For my 03 LX I have Ts (white wire) on terminal 12 and Tc (pink/black) on terminal 13. Cg in DLC3 is E1 and I’ve always seen it on terminal 4.


Toyota Techstream Feedback:

I already own a really expensive Mongoose Data cable. My Father-In-Law liked it but didn’t want to pay the huge cost. He only wanted to read error codes, not reprogram anything.

I bought one of those cables for my father-in-law so he could read ODBII codes. It claimed TIS support, but for $35 I was sure this would be read only.
It arrived earlier this week. I just opened the box today. It came with TIS software and drivers. I installed it and it *works* exactly the same as my much more expensive mongoose. It has a full version of TIS, no license required. I reprogrammed a couple of options – works great.

This is $35 folks! Less than the cost of what some of you are paying to enter your TPMS codes for winter/summer tires at the dealership. Shipping took a couple of weeks.
