What is an Aerospace reader?
No device I am aware of will tell you there is a faulty cat temp control unit unless you happen to be hooked up and monitoring real time when failure is happening. Then when real cat temp is in normal range and warning is on you can deduce a failure. To my knowledge only one of the Ferrari proprietary units will do that.
You really need to monitor engine parameters, left and right, know what they are supposed to be and then make a determination if there is anything going on that will explain a cat overheat. If that produces a negative result throw away and replace both cat temp control units because if they both aren't bad now they soon will be.
