It claimed TIS support, but for $35 I was sure this would be read only. I bought one of those cables for my father-in-law so he could read ODBII codes. He only wanted to read error codes, not reprogram anything. My Father-In-Law liked it but didn’t want to pay the huge cost.
I already own a really expensive Mongoose Data cable. Cg in DLC3 is E1 and I’ve always seen it on terminal 4. For my 03 LX I have Ts (white wire) on terminal 12 and Tc (pink/black) on terminal 13.
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. It’s worth noting that there is some erroneous info for the DLC3 terminal pin outs. Regardless, Tc and Ts are connected in parallel. It provides easier access (for me at least) to the main players for AHC diagnostics which are the Ts, Tc and E1 ports. 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.
