Tire pressure alarm

What is the deal with the tire pressure monitoring system alarms on my 2015 GS 1200 Adventure. I have the correct tire pressure showing 42 LB the air temperature outside was between 59 and 92 F and the alarm showing 33 lb how do I calibrate that alarm so that it doesn't come in and it shows the correct pressure?

Only way I know to disable the RDC is to switch to Enduro or Enduro Pro. I had a similar issue with my off road tires that had a max PSI of 35. Fine for front tire, but everytime RDC showed 33.5 for psi in rear tire a fault would pop.

When I add air to the tires, I do the following -

1. Tires are cold (eg. Morning)
2. Note the temperature where the bike is sitting
3. The 42/36 is based on 20C/68F
4. For every 10 degrees F above 68, add 1 extra psi. So the cold rear at 78f should be pumped up to 43
5. For every 10 degrees below 68f, subtract 1 psi. Cold rear at 58f s/b 41psi
6. Steps 4+5 account for density based on temp

See if that stabilizes the psi...

flat batteries on the RDC?

I know its a '15 but stranger things have happened...

I'd rather have a bottle in front of me than a frontal lobotomy

Did this just start? Im guessing that maybe the sensor battery is going low?? I dunno??? Ive a 17 GSA and am not overly impressed with the TP system and will (if its possible) have my dealer turn it off.

Low battery

Low battery Will cause all sorts of problems if youíre adventurous you can get the batteries they are about six bucks apiece and a little silicone and soldering and you can fix your sensors if they drop a quarter of a volt sometimes they will take 10 miles to come on or donít come on at all I have change batteries on both of my sensors I have a 2015 R1200GS The battery are. (Maxwell CR2050HR ) Plenty of videos on YouTube how to fix your sensors better than paying $200
