For my 2000 TTQC, I did the following
- AC or Economy, doesn't matter
- depress/hold Recirc button
- depress Up button and release both
- LED display goes bright and flashes one of the C-codes (they go 1C to 79C)
- rotate (turn-and- hold works) fan speed selector (LH **** in US) CW or CCW until you get the 49C code
- depress and release recirc button, display shows C* temperature.

My TTQC runs about 83*C here in SE GA right now. Hard acceleration up to 160k/96m makes about 85*C.

OK, here's my question:
- who has the breakout of all the C-codes?
- If no universal ist, which one is oil temp, boost, a couple of others?

Someone did this code list, I cannot remember who but I'm not going to take any credit. Hope it helps.
