You may have a defective coolant or air temp sensor. These need to be accurate in order for some of the monitors to run. Your going to need a diagnostic scanner to see the data so you can determine what is wrong.
If you had replaced or unhooked the battery just pryor to geting the smog then thats the problem. Just drive the truck for a couple days and you should be fine.
You will still pass the test if you still have 2 monitors not set. California allows that. 3 fail
