Toro TSM-02 2 Station Expansion Module for TMC-212
NEW!!! Toro 2 Station Expansion Module for Toro 212 Modular Controller. Expands the number of stations (zones) from 2 to 4, 6, 8, 10 or 12 Stations. The TMC? 212 controller has a new look and added features. It's now even more valuable!
*Expansion module adds two stations to existing controller / timer.

There are four components to a sprinkler system. First is the module. Second is the base unit. Third is the valve and fourth is the wiring that connects the base unit to the the valve.
By switching the modules you eliminate one of the variables, as long as they work in the two working zones.
Second, a good inspection of the base unit will let you see if there is visable damage or corrosion on the circuit board or place where the modules connect. Corrosion could cause a bad contact with the module or might have damaged part of the board. If everything looks normal, then you don't have an obvious issue. Snce the circuit board is electronic and has very minute amounts of electricity flowing, you won't always see that something is wrong.
Make sure that the wiring between the base unit and valve doesn't have a short or a cut in the wire. A simple ohm meter can be used. Take a resistance reading of one of the good zones with the module attached or with the module unattached AND the two wires twisted together. I would suggest the module method because you will get a reading somewhere in the middle of the ohm meter's range. If you get no reading on one of the bad zones, that would indicate that the wire is cut somewhere. If you get a significantly different reading, it would indicate some other wiring issue. This will eliminate the third component.
Finally, comes the valve. My experience is limited. If I'm sure that it's not one of the first three items, I'd call a professional to assist with troubleshooting and, if necessary changing out the valves. Based on my experience with irrigation piping, when it's necessary to change out a valve, there's a lot of digging, probably pvc pipe cutting, parts replacing and gluing involved.
Good luck, at least you are dealing with quality merchandise.
Also you may check the AC adapter, to make sure its leads in the panel are hooked up . If you experienced a lightning strike on a non protected circuit, it may have "fried" the board. Replace the controller, the modules are probably still good.
Are you asking if Toro and Rainbird expansion modules are interchangeable?
