GL1800 (2012+): TPMS light

[showmerider]

Last week while riding to work my TPMS light came on, so I pulled over, shut the bike off and checked air pressure in both tires and all was good. I went on to work and within 4 - 5 miles the light went out. The very next day it came on again, but since I couldn't feel any wobble I kept going and after about 8 - 10 miles it went out. That was Monday and Tuesday of last week, I haven't had any more false alerts until riding in this morning and the TPMS light came on again for 8 -10 miles and went off. Has anybody else had this problem? Any suggestions on what might be causing it?

As I understand, it takes a little while for the tires to "warm up" so to speak so as long you check pressure before you ride, all should be well. YMMV

Had some "mystery" lightings-would,ride1 mile to gas station to find both tires within 1 pound o f recommended. Then found that if I rode a few,miles rhe loght would go out. Pressures not checked daily since rhey rarely need more air, so I'm mystified, too. Maybe that's why Cruiseman likes that aftermarket system...

Just to clarify, the light didn't come on when I first take off, it would be after about 10 minutes (approx. 8miles) of riding. That's why I'm confused. I understand the low tire pressure light flashing till it warms up (I'm a darksider), but after everything is warmed up and it comes on out of the blue and goes off again after a few minutes of riding does'nt make since.

I have had the same problem its could be a weak battery in the TPMS censor i played with tire pressures didn't help, it dose not blink anymore just have a solid light now. If your under warranty you can have it looked at but you will to put a Motorcycle tire on it. once you put the car tire back on the light will likely come back on as mine did. Never like this TPMS system but it is better then nothing. Saving for a Doran System one which will show the actual pressures.

Thanks Yellowbird, I hadn't thought about the TPMS battery. Any idea how long they are "supposed" to be good for?

My '14 does the same thing. Doesn't matter if its a cool morning or a warm one. About 1/2-1 mile the light comes on, 5-8 miles later goes out.
First couple of times I stopped and checked pressure front and rear, both over the minimum threshold. Now I just ride it out.

Afternoons when I leave work, no issues.

By "comes on", do you mean it starts flashing or stays on? I also assume you are talking about the pressure light not the TPMS light. If the TPMS light stays on it's an issue with the sensors. So - if the TPMS light comes on then goes out, I would check the battery. And just because you have a new bike does not mean the battery is not bad. I had to replace a battery on my 2012.

It is the TPMS light and it comes on and stays on for 8 - 10 miles after having ridden for about that far. So far it has only done it in the mornings never in the afternoon. My bike is also a 2012, so did they replace it for free or was it out of pocket?

[genedjr]

Battery's are not warranted. I replaced it myself. And the batteries are not officially replaceable. There are instructions available, just google it. I would check with your dealer - they may replace it anyway.

Have you run the DTC codes?

Here are the codes:

The TPMS light on my bike lights up when its around 40* F after about 5 minutes or so of riding. Tire pressures were checked and correct. My bike has a new TPMS sending unit in the front wheel, a new TPMS receiver, and new battery in the rear wheel TPMS. On cool mornings I cycle the ignition after the light stays on a while and it goes off and stays off. Fred H has reported that the Li-ion battery require a wake up time ( sometimes ) when cool. My 2012 rear TPMS sending unit battery was going dead around 32,000 miles. The GL1800 TPMS system was replaced under warranty. The TPMS wheel sending unit including the battery is the way Honda sells it, so the battery was covered by warranty. I did have the TPMS sending unit battery in one of my spare wheels replaced at the "Battery Box" for $3.00 including installation. If it were my bike I would use the service manual to trouble shoot the DTC codes and then if it showed a dead battery take it in for warranty.

TPMS service life is determined by actual on time meaning how much time it spends activated by riding rather than calendar time. If you spend a lot of time riding your battery service life will be shorter.
