Disabled TPMS with TigerTool, Red Warning Light Remains Illuminated

[LB36K]

Hello and thank you for any help you can offer.
I disabled TPMS with TigerTool, and the red warning light remains illuminated on the bike's display.

I enabled it and then disabled it again. Then disconnected the battery... It's still on. Any insight?

Did you disable it from the instruments (Insts) tab or the TPMS tab in TigerTool?

Doing so from the Insts tab will remove it from the dash and hide any warnings but the immobiliser will keep transmitting data over the CAN-bus. Doing so from the TPMS tab disables the system completely but warnings will still be shown on the dash unless you also disable it there. This is because the dash is expecting to see pressure data and there is none.

 Hi, thanks.

At first I just disabled it from the TPMS Tab, then after posting this request for help I found the INSTS Tab and disabled it there also. And the light remains illuminated.

LB36K. Since going to the darkside on the rear of my Trophy, and running 31PSI in the rear my red warning light remains on. I'm not concerned by this, I simply put a small piece of black tape with a very small hole in the centre over the light. The small hole is so the light is not as intrusive on night rides. I also ride with the tyre pressure readings always on the dash. That way I can monitor any fluctuations in pressure even though the lights constantly on. Before TPMS systems became the norm a rider was always aware that movement in the rear possibly indicated a reduction in tyre pressure, still works for this old fella. Cheers.

And with the much stiffer sidewalls on tires for heavy bikes now it helps to have that advance information before there's enough loss to realize it in the handling.  Having said that, TP monitors can't reveal and impending blowout!   Yep, had one of those with two up on a 250 Ducatio when I was 18.  Fortunately it was at 35 mph.  No crash, but a harrowing experience.  My monitor display is up all the time and I only toggle to other information on the second display and toggle back.  They've already caught a somewhat rapid loss one time that gave me time to get off the road safely.

Yeah, tape may have to do..

The light is controlled by a byte within a message on the CAN-bus, sent from the immobiliser, which would suggest that you've possibly not managed to disable the TPMS.

If you read my instructions in the following post...Trophy CAN Bus Stuff...but change the command "AT CRA518" to "AT CRA600" you can monitor if there's TPMS data on the bus. If the TPMS is enabled in the immobiliser you'll see something like this...

600 00 B4 3E 38 00 04 00 0A
600 10 D2 3E 38 00 04 00 0A

These messages will be repeated at approximately 1s intervals. Decoding these gives you...

600 00 B4 3E 38 00 04 00 0A
00 = Front Tyre
B4 = 180 / 5 = 36psi
3E = 62 - 50 = 12°C
38 = Status1 (e.g. battery, wake state)
00 = Ignore
04 00 = Incremental counter
0A = Status2 (e.g. comms, leakage)


600 10 D2 3E 38 00 04 00 0A
10 = Rear Tyre
D2 = 20 / 5 = 42psi
(The rest as above)

In the above examples, the last byte in each line is the one containing the TPMS warning light control bit. If you convert the hexadecimal number to binary, then check bit2 you will get the TPMS light status.
e.g.
0A = 0000 1010 = Light Off
0C = 0000 1100 = Light On

I'll give it a try (when the rain stop:) Thank you!
