ABS sensor TPMS system tend to require around 8psi min change before its detected i have found from experience.

Mine triggered on the M180 whilst towing the caravan. The Columbus didn't flag any particular wheel, instead highlighting all four.

Cue a quick stop in the HGV park in the services for a check. No problems at all (apart from the smell of p*ss)

Thats a system error like i had when the car was new for the first 100 miles or so...

 

It should say which tyre was at fault..
