Techstream not showing Transmission ECU data on 2021 Prado

[ptommo59 Senior Member Find all posts View Profile Close ptommo59]

I have tried connecting a copy of the V16 and V17 Techstream software via both a VCI Firmware V1.4.1 cable and VXDIAG Nano to my 2021 VX and in both cases the Transmission (ECT) ECU and related data list items does not show up ( Everything else is there including the customisation options).

Has anyone else been able to get the ECT data to show up and if so what are you using?

I recall that transmission temp codes changed with the 2021 model.
Look for the latest Techstream version and shelve the old ones.

Thanks RPP,

It not the techstream version as the V16 I have covers through to late 2021 and the V17 includes the Aug 2022 tech update in both the Other and Europe Regions. Had no trouble connecting and selecting the correct model, year range and engine and options to get to everything other than the transmission info.

I'm assuming it's a software setting or the VIM interface that's causing my issue and with luck someone has cracked how to sort it and can pass on.

Finally solved :-)

In Techstream V16/V17 the new version ECU only shows up as 'Engine' for both the Engine and Gearbox live data (previously it was either separate items or labelled as combined 'Engine and ECT') so no issues there.

My original problem was I could not see the trans temps in the default data list (Primary), I eventually got these to show up by changing the selection box on the bottom of the page to either 'All Data' or 'ECT' hope this helps anyone else who was stumped by this issue.
