What causes a Denso Air Conditioner communication module to not work properly?
- J
  jessedawsonSep 12, 2025
  If the communication module on your Denso Air Conditioner isn't working properly: * Check if the “P” LED indicator on the communication module is off because the AC power isn't plugged in and the communication module battery switch is in the OFF position. Plug in the AC power or set the communication module battery switch to the ON position. * If the “L” LED indicator located on the communication module is off, it may be due to poor or no cellular (LTE) signal, a connection issue, or the unit is located in an area with high signal interference or an area that restricts LTE signal. RESET the communication module by pressing the reset button and confirm the “P” LED indicator blinks one time and stays on.
