A previous thread here asked about tire inflation indicators.
Just had an issue with mine today that I though I would share.
Temperatures here have been low, and suddenly my inflation indicator came on. Tires were down to 25 psi, so I inflated them back up to
32, as specified.The light did not go out.
Called the dealership for an appointment and told what was wrong. Service manager asked if I had balanced the tire inflations, and I said I had..."Including the spare", he asked? (Well heck no, I had not checked the spare)
Armed with this clue, I checked the spare, and found the pressure had dropped to 20 psi. After I balanced that, the light went off and everything was fine.
Just a hint to others who might have these systems, but who have not really looked into how some of them work.
