Although everything else works, it may be that the router isn't communicating properly with the Kindle. Switch the router off for 30 seconds then switch it back on. This should get it to restart comms with all devices and assign IP addresses.
Sigh...there can be alot involved in NO COMM faults. Do the instrument warning lamps come on with the key as normal? Do they all go to self test modes when turning to start? Most GM products either have a dedicated fuse for DLC or use the Radio fuse. If you have a meter or a testlight, pin 16 (Looking at the DLC, top side is the wider of the 2 sides, bottom.narrow side furthest right is pin 16) will be the 12v power port. If you can test for power there, and you dont have it, you have a broken wire or a blown fuse or a bad connection most likely, or possible ignition switch issue.
If you DO have power (Minimum 10.5v to be sure it will connect), then it becomes more involved. You need to start checking grounds as well (DLC Pins 4 and 5. Top left is pin 1, count to the right) and then checking modules directly for power and ground or checking comm lines at the can buss connector. This really requires a system diagram for all modules connected on the comm buss, and a wiring diagram to know which wires you will be testing, plus its worlds easier if you have an enhanced scantool capable of talking to all modules on the vehicle. If no modukes can communicate, then you can backtrack from your DLC till you find where there is no signal, but that could take awhile. However if some communicate and others do not (Your car probably has 15 modules that can comm) then it can really speed up the process because you will then know where the fault ISNT, and can narrow down the search for locations.
Having seen a few GM systems get upset with water intrusion, or individual modules pulling down the buss, you could try disconnecting the ABS module connector and rechecking comm. I have seen loose plugs on that, as well as burned out ABS modules cause NO COMM. I only start there because its usually easy to unplug and test the ABS.
Aside from that, you really will need test equipment and accurate diagrams to properly proceed. But with any luck, the power and ground testing may get you going. Id start there if it were at my shop, and proceed to scan tests and buss wiring checks next.
Error codes from American Standard Pub 18-HD32D2-8, which is a one-sheet document that came with my American Standard air-conditioner:
29 = not listed
129 = not listed
80 = HPCO Fault - problem is in outdoor unit - Desscription: High Pressure Monitor Fault (hard lock out, cycle power to reset)
91 = Communication Inactive Fault - problem is in air handler - Descriptions - COMM Bit Master Clock Error, COMM Heat/Cool Demand Error, Serial Motor Communication Inactive Error
91 = Communication Fault - problem is in furnace - Descriptions: Blower motor no COMM response, Inducer motor no COMM response, Loss of heat/cool demand, Loss of clock signal
91 = Communication Fault - problem is in outdoor unit - Descriptions: Loss of Heat/Cool Demand Message (COMM), Loss of Bit Master (Clock Signal)
91 = Communication Fault - Description: Comm line is dead and no bits have been received.
By the way, I do not recommend American Standard. I've had mine 14 months and it just blew up - the entire control panel blew. My advice to you - think about a different brand.
We had the same problem and the above solution didn't work. It wasn't anything your son did, but obviously a problem with the computer itself. Disconnect from the mains and pull out the battery with the computer still going, then restart. When prompted just open Windows normally and the wifi was now functional again.
The Fail To Comm message is not related to your low battery problem. A Fail to Communicate occurs when the alarm system tries to send a signal (alarm, trouble or restore) to a monitoring service but can't. Most often the causes are telephone related. Has your system been disconnected from it's phone line? Have you recently changed phone services from your main carrier to an internet provider that provides VOIP service? Sometimes alarm systems have a hard time communicating over these services. Whatever the reason for the
