No Wi-Fi Module Found control panel error

When an end user navigates to the Wi-Fi menu, the control panel displays "No Wi-Fi module found". 

Environment

This error occurs when attempting to perform a standard Wi-Fi connection for a home standby generator that has a compatible Wi-Fi module installed: Which generator controllers are compatible with aftermarket installation of the Wi-Fi, Ethernet, or 4G LTE? devices

Causes

• The wiring harness for the Wi-Fi module was not installed correctly, or has become disconnected
• The unit does not have a Wi-Fi module installed

 

Troubleshooting

Important: These steps require opening the generator enclosure and working near wiring connections. Put the generator in OFF and allow it to cool before removing panels. Avoid touching terminals and wiring, including the harness area where N1, N2, 23, 94, and T1 wiring may be present. If you are not comfortable performing these steps safely, contact your nearest authorized dealer.

Why this may be necessary: Even when the harness is connected and the module has power, the Wi-Fi module can become unresponsive (frozen) and stop communicating with the controller. A hard reset (power cycle) restarts the module’s internal software and restores communication so the controller can detect it and the module can be connected again.

1. Remove the side panel on the generator. 

2. Verify the module harness is plugged into port 1 on the control panel.

• The quick connect should be plugged into port 1 and should have a total of 4 wires in the harness (black, blue, red, and white). See the picture example below. 
• If it is not plugged in, take the side panel off, locate that grouping of wires, and follow it back until you locate the quick connect end and reconnect it. Make sure you hear the harness make an audible click when going into the control panel. Be careful as this is where your N1, N2, 23, 94, and T1 wires are all located.

3. Verify the module is blinking green. This indicates that the wiring is properly connected and the module is receiving power.

4. If both the harness is plugged in and the module is blinking green you will want to do a hard reset on the generator and module (Method 2): How do I hard reset or power cycle a Mobile Link device?
