What happens when you reset the ECU on a Honda Civic?
Resetting the ECU will clear the trouble codes and restore the system’s memory so it can “learn” the aftermarket parts. The process is straightforward and does not require the help of a professional mechanic or Honda dealership; however, you will want to follow the instructions carefully and make sure you have completed each step correctly.
What to do if your Honda Civic a / C is not working?
As an alternative you can bypass the switch temporarily. The A/C pressure switch receives a signal from the Heater Control Panel (Connector A pin 4 @ heater control panel). And the Heater Control Panel receives a signal from the A/C on/off switch (Connector B pin 15 @ heater control panel, this looks like it should be 12v or 5v one of the two…).

Do you have to flash ECM to VIN number?
Hi there. If you were to get an ECM (engine control module) from the dealership, the dealership will flash (program) the ECM to the VIN number to your vehicle and all of the specs. However, if you were to purchase an aftermarket ECM, you also will need to have it flashed to match your VIN number to your vehicle and all of the specs.

Why does my car anti theft system not work?
Check the key. The key itself could be the culprit for the anti theft system car wont start. The keys have a built-in chip that sends a code to the alarm system when you insert it into the ignition. That chip won’t work in case of a broken or damaged key.
