Tire Pressure Monitor

Understanding that the tire pressure information is sent wirelessly to the cycle monitoring system, where is the antenna / is there a separate antenna located in the front and rear of the cycle? Or, is there one antenna in the TPM system housing? Thanks.

Re: Tire Pressure Monitor

On my K1300S it was under the rear seat.
It have a Schrader Electronics sticker on it.

Re: Tire Pressure Monitor

I have the same except it also incorporates the alarm system. What I need to know is where the receiver antenna for the TPM is located.

I noticed that when the INNOVV K2 camera system was installed on the cycle, only the front tire pressure would not display, was slow in displaying, or would drop off the display. The rear behaved normally. Now that the camera system has been removed, the display behaves normally, thus ruling out a bad battery in the wheel sensor. I am trying to determine why just the front display was malfunctioning, if there is an receiving antenna near each wheel for each sensor or just in the TPM assembly. I am trying to determine if the proximity of the camera, camera system power converter and/or the DVR was a source of EMI that caused the problem.

Re: Tire Pressure Monitor

Sounds for sure like an EMI/RFI problem.

Considering the front Wheel Pressure Sensor is furthest away (versus the rear Sensor) from the Schrader Electronics Unit under the Rear Seat, its a clue that something (INNOVV K2?) in between is interfering...if the TPMS Antenna is inside the Schrader Electronics Housing.

You can try wrapping Aluminum Foil around the Schrader Electronics Housing and then ground the Foil to the minus Battery Terminal. If you lose both Pressure Sensors then it would suggest the TPMS Antenna is inside the Schrader Electronics unit.

As for the INNOVV K2 - maybe try mounting it further away to avoid close proximity to the Schrader Electronics unit...to the left side of the Headlight behind the Fairing?

Re: Tire Pressure Monitor

I am curious why the front tire pressure indication is effected, but the rear is not.

The camera components under the seat are nearer the alarm/TPM module and the rear wheel. I would assume the rear indication or both wheel indications would have problems, not just the front if this problem is generated by the power convertor or the DVR. The front camera was mounted directly over the front wheel so that makes it and a possible antenna location items of interest.

I have never heard about a TPM antenna in front, but don't see how a weak signal from the front TPS could make it through the forks, frame, radiator, and engine to the alarm/TPM module at the back of the cycle. I am assuming it is a weak signal due to the longevity of such a small battery.

Also, if the antenna is internal to the alarm/TPM module, a grounded shield will disable the entire system and make the use of the alarm key fob remote unusable.

I was just hoping this antenna deal would be an easy answer. I am not surprised since BMW is so tight about electrical information. Thanks to all who have offered input.
