TPMS Malfunction After ECU update

[markradtke18]

Just had bike returned from dealer after having them perform first service interval and take care of two issues-after the ECM recall.

A) Heated grip symbol did not appear in display after grip install. They got that fixed.

B) TPMS was reading backwards. The pressures were accurate but what was indicated as the front psi was actually the rear psi. What was indicated as the rear psi was actually the front psi?

The biggest issue this causes is for the low tire pressure warning to activate.

In speaking to the dealer, they confirmed that the two were backwards but weren't sure how to fix? I've asked them to check things out with Triumph HQ and try to get this right at the time they do the cylinder head recall in a couple of weeks.

Does anyone who has had this same issue know what the real fix is? If so, I would pass this along to the dealer. Thank you in advance for your insights and experience.

Sounds like your Dealer is not too familiar with the Triumph diagnostic software
that they use to program the bike with. ( Not that I am either though  ! )

The lack of Heated Grips symbols appearing in the Instrument Panel display
is simply due to not having set that option within the software.

The TPMS system uses coded pressure transmitters in each wheel.

Prior to commencing the ECM replacement, the Dealer is supposed to read
the Codes, then re-program them back into the new ECM afterwards.

They appear to have programmed them back into the wrong positions 

As far as I know they should be able to plug back in to your Trophy
and re-program them correctly.

The TPMS sensor codes should have been provided on stickers
that should then be attached to your Handbook,
so it might be worth checking you have those

All excellent suggestions....
Makes good sense to me.
It is a little frustrating to have these issues develop, but it's a little learning for all of us.
Thanks Coconut.

My TTSE had that problem when new. I had them fix it at the 500 mile service. Neither the heated grips nor heated seat would show in the display, but both worked fine.

I have a hard time believing the dealer cannot figure out that the TPMS entries made in the software program were but in the opposite order than they should have been.

They should be able to fix both those problems while you wait, in just minutes.

The thing it unfortunately highlights is the poor attention to detail which makes you doubt their abilities over anything else... After all, if they can get front and back muddled up how about left and right..... Positive and negative..... Newton metres or pounds feet!

If the garage isn't familiar they should know these things and double check everything they do... "Measure twice and cut once" can be read as "read the service manual twice and set the ECU up once"
