Here is the information that I found.
The pump motor continuously monitors the thermistor temperature sensor for temperatures which are too high or too low. Different operating temperature setting are required for the decklid and the folding top functions. If the control module detects a temperature between the pump motor pre-alarm setting and the pump motor alarm setting, the current open/close operation shall be completed, but no new top operation will be allowed until the pump motor cools below the pre-alarm setting. If the temperature reaches the pump motor alarm value, all top operation will cease. A low temperature value is sent over the class 2 serial data that will also cease all operation when the outside temperature is below this value. The pump motor temperature settings are:
" Too high pre-alarm of 105 C (221 F)
" Too high alarm of 115 C (239 F)
" Too cold for folding top operation of -20 C (-4 F)
" Too cold for decklid operation of -30 C (-22 F)
There is only one way to read this information, and that is through a scan tool. It could have a(n) open/faulty tempo sensor, software issue that could be corrected by reprogramming, circuit faults, or even the module. Without knowing what the temperature value is, I couldn't make an assumption.
