The scanner was working find until about 3 weeks ago.  It doesn't seem to matter what vehicle I try, I can get no results.  The unit is a little over a year old.  I have updated to the latest v5.31 software and have tried other previous versions but the results are still the same.  I have recently tried the sensors on a 2008 HHR, 2012 and a 2016 Honda CR-V, 2010 Honda Odyssey, but will not trigger or retrieve any info.  Otherwise the scanner appears to be functioning properly.  The tool information shows the serial no. as T416310291. Burn date as 07/26/16,  the S/W ver. as V5.31GL and the H/W ver. as V3.00.  I am using it in the US market.  Can someone help? or experienced similar problem and solved it?

 I have tested it on several different makes of vehicles, but I'll use the 2008 HHR for this discussion. When I try to test the unit on this vehicle, after about a minute, the scanner reports that no sensor is present, but the vehicle, its self, is reading the sensors and the tire pressure.  It does not matter what vehicle I try the scanner on, I get the same results that no sensor is present, but the vehicles have sensors and they are in perfect working order.

 

I tested a key fob and found this Problem – (2008 HHR key fob)

 I selected RKE & RF Monitor from the Tool Kit screen. The scanner unit shows a full bar graph with a 315MKZ notation and immediately begins to beep continuously while apparently transmitting a continuous 315MHZ signal for approximately 50 seconds and then switches to a 433 MHZ signal transmitting it for about 25 seconds and then switches back to the 315MKZ signal while it continues to transmit and beep until you back out of the screen.  The bar graph remains full while this is all going on.  My intent was to test the 2008 HHR key fob.

I have purchased a new TS501 and it tested all the buttons on the key fob with no problem.

I also ran another test using the new TS501 and the bad TS401 on the 2008 HHR.  I held both scanners to the tire sensor and first tried triggering the sensor with the TS401 and neither scanner could read the sensor.  I then tried triggering the sensor with the new TS501 and only the new TS501 could read the sensor.  I tried it several times and obtained the same results. So I concluded that the TS401 is not triggering or reading the sensor.

 I have tried different versions of the software and I am on the latest, v5.31 at present, and the scanner will not work on any.  I am using the US market in settings etc. and my results are still the same, I can trigger no sensors or obtain any readings from a sensor that I know is working or test any key fob, the scanner is useless in its present state.  I plan on giving support a phone call and see what I can get done with it, that is if it is affordable.  The cost to repair may be not worth the effort.

I appreciate all the responses.  My problem has been solved by Autel support in New York.  They ended up replacing the unit.   

Autel Support sure stands behind their products.  I contacted Autel Support in New York and they tried some things by desktop remote but the unit did not respond.  They then had me ship it to them and 12 days later I received a replacement unit.  My sons and I together own 5 different Autel Diagnostic tools and we are well pleased with their products.  I would definitely recommend their products to anyone in the market for diagnostic tools.  Again, thanks to everyone.
