Tesla Small Drive Unit TMPHS value
Posted: Sun Jul 14, 2024 5:42 pm
Hi All,
Looking for help with the Tesla Small Drive Unit using a v6 board running software v5.27.
For some reason the tmphs keeps jump up when I floor the throttle and dropping back down when the car idles. It goes as high as 90 degrees for about 1 second then drops back down to about 38-45 degrees. The tmpm value stays constant around 36-42 since the cooling pump is running.
The problem is this means the default 85 tpmhsmax value keeps being triggered resulting in a TPMHSMAX error. I have increased it to 105 to make the car drivable at slow speeds.
What is expected and recommended here?
