Welcome. My name is ***** ***** would be glad to assist.
In order to see if the issue is with the program or with the modules, please take the wires off of zones 1 and 2, then remove 5 and 6 as well.
Then connect the wires removed from 1 and 2 to the 5 and 6 locations. The commons should all be together and nothing needed with them.
Then you can activate the 5 and 6 zones to see if the 1 and 2 zones come on.
This will tell you if the zone valves are good and operational.
If they are good, then you can put everything back to its original positions.
If you need Zone modules, you can get them through Toro--CLICK HERE for replacements
Now if you have any open spots for modules, you can install new ones in the 7 and 8 position if needed also, as I do not know how large your unit is and the total slots available for the modules.
If you have a voltage meter, you can also measure each terminal on the non working zones.
Set the meter for 24 volts, then put one lead on the terminal and one to the common terminal.
Turn on that Zone and see if you read 24 volts.
If you have 24 volts, there is a problem with the wiring or the valve, if you do not have 24 volts, it is the module failure.
Let me know how it progresses and we can continue as needed. Wanted to provide as much information as possible to start.
