So, the weather got cold, and I'm throwing a 20F206. It was also wet when I first got the DTC.
This is: Heat management module activation, line disconnect. (Whatever that means exactly)
I clear the code with Ecutek: it vanishes for 2 days, then reappears. Clear it again, it does not come back on after 20 minute drive today.
Car is in limp mode according to Ecutek data log (attached--logged when idle after light came on), but drives otherwise fine, so it's not the kind of limp mode that limits throttle, rpm, etc.
Questions:
1) Anyone else deal with this?
2) What is best solution? I'm thinking buy a new heat management module and replace?
I'm tuned so, Toyota ain't gonna warranty it.
3) What would you do?
Suggestions guys?
