2011 Sienna crank, no start when COLD

Question

Hi support team,

My 2011 Sienna G-key start all OK in summer, but it doesn't work when WINTER is coming. S/N 002B04 241048 connected by THAR-ONE-TOY9 (just plug and play). I did connect 2 wires for sliding doors by soldering and crimper (no T-taps).

Already upgrade to latest firmware. Tried TACHNESS ONLY but no hope, still CRANK but NO START. I'm connect with RFK442 remote.

It happened to me last year, same issue. Work fine in the summer but when it's cold out there, the vehicle just CRANK NO START. When I get into the vehicle and remote start it, leave the key next to the key cylinder, it start right up every single time.

Moreover, I've re-checked the wiring connection. There are "CUT" at the SILL data (D4&D6) and the AUTOLIGHT (D1&D3). Do I need to do anything about these "CUTs" when I'm using THARTOY9?

Thank in advance for your support.

You could try rolling back the firmware to see if it yields different results.
