Tyre Pressure Sensors

[Mr Bean]

Any advice gratefully received.

My front sensor stopped working, I bought a new one, fitted it when a new tyre was needed, connected my GS911 and the sensor gave a reading of the tyre pressure in the bike display. After a few minutes the reading in the display disappeared for the front.

I've been for a ride today and there is no reading from the front - what am I doing wrong.

Apologies if I have missed a previous post on this.

Thanks.

Did you enter the new serial number of the TPS in via the GS911 and register it to the ECU?

 

[Mr Bean]

No, I thought with the latest software it wasn't required - but am quickly getting the feeling I may have misunderstood!

Is this my error, even though it did show the sensor as working ok?

Thanks for your help.

I haven't fitted new sensors myself but I have gone into the GS911 menus for the TPS and played around with deleting the serial numbers. After doing that the ECU didn't automatically recognise the TPS (with the bike stationary - not sure if they would wake up if the bike was moving) so I had to go back in and re-enter the serial numbers. I would guess that's what you would need to do - enter the new serial number using the GS911 and then when you ride the bike and the sensors activate above 30kph, they should be recognised.

Thanks again,

I've emailed the retailer to see if they kept a record of the bar code.

Seems strange because the GS911 did pick it up and showed as being ok and as I mentioned the reading was showing on the dash.

I've ridden it three or four times since fitting and it hasn't picked it up since.

If the GS911 had recognised the TPS then the serial number will be showing on the GS911 menu display - if you know the number for the old one, check to see if its that which is still showing in the GS911. If the new one is actually a secondhand one do you know that was working in the first place? May need a new battery if thats the case.

The GS911 was showing a serial number and showing it was ok. I'll reconnect it to see if it is the same number as on the one i took out.

The replacement was a new one from the States at £40.00 - have now replaced the battery on the one I took out as the rear one will no doubt fail shortly!

 

[Beemerman59]

£40 is a heck of a price especially shipped from the USA - they're normally about £80 here I think.

 

[Mr Bean]

I may be mistaken but thought quite a bit more than £80.00

Connected the GS911 up again today and this is the information on screen - any ideas?

It won't read anything from the sensors if the bike is stationary - you need to "wake" the sensors up which means riding the bike up to about 30kph. An alternative with the bike static is you can try to quickly release air pressure in the tyre for about 10 seconds - this is also supposed to wake the sensors up. Thats why the input signals are empty. My guess on the data in the controller status is that's the last info that was recorded by the ECU although thats a guess on my part. You could try the G9111 forum for further info.

I have to ask the question though, given the cheap price of the sensors is are they OEM? And if they're new they should have come with a bar coded label with the sensor numbers on them. Are the ones showing in the GS911 readout the old numbers or the new ones?

I did try to wake the sensors by rapidly deflating the tyre and it made no difference - I got a time out message.

The sensor looked genuine with the correct markings and my GS911 appears to recognise the sensor but I can't be sure.

I have since fitted a replacement battery in the old sensor which may answer the problem.

There was a bar code number on the sensor but i didn't understand at the time the need to write it down for later!!

I have put the question up on the GS911 forum.

Thanks again,

Bean
