Hi, my name is Jose Sebastian, your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologize for any delay.

I try to be here most weekdays and some weekends. If you respond and I do not respond back right away I will do so as soon as I can.

Dear customer, you are presenting a clear deprogramming problem in the alarm system. The problem is that I do not know if it happened due to the installation of the electric seat or due the flat battery.

When a battery is flat it is normal that certain electronic modules are deprogrammed in this case the alarm module, but solving this is not complicated but it does require a diagnostic tool with Honda software to be able to access the electronic modules including the alarm and to be able to do a factory data reset in this way the vehicle would be working with the original data, in this case the alarm module would be working normally.

This in the case that it has been deprogrammed due to a battery discharge, the problem is that if when installing the seat one of the circuits in alarm was touched, it could have caused a problem in the wiring of said module or a defect in it. Would be good to verify how you made this installation to verify that there has not been a short or high voltage that the module could find, if it is possible to get a test module to rule out.

Have you understood me, dear customer?

the install of the seat was done within 1 hour of disconecting the battery. the battery was reconnected 48/72 hours later

It may have been more the disconnection of the battery than the installation of the seat, because since the alarm module has been unconfigured, the best thing to do is to do a reset of the factory data through the diagnostic equipment, in anyway you can try a manual reset as well.
Manual reset.
1) Turn the key to ON position without ignite the engine.
2) Disconnect the negative terminal of the battery.
3) Wait around 3 to 5 minutes to let all the modules delete its data.
4) Turn off the key and take it off.
5) Reconnect the negative terminal.
6) Turn again the key to ON position and wait around 30 seconds to let the modules restart.

If this doesn't work the diagnostic tool will be needed.

Do you understand me, dear customer?

that has not solved the problem

Dear customer, if this did not sort out the problem, then you have to reprogram the module and delete the error code with a diagnostic tool. When the manual reset does not work, it means that there are error codes store in the ECU and the alarm module must be programmed again and the error codes stored delete.
The diagostic tool must have the Honda software to be able to gain access to this module.
