As stated in the other forum;
The thermostat is designed to fail open. Not like domestic vehicles that fail closed. Your thermostat probably isn't the issue. There are 2 temp sensors that might be causing the issue. Check the connectors. Your error means it sees the temp as completely out of range when compared to the rest of the data that it's processing.
In order to finish FIRST, you MUST first FINISH !
