Background:
The car has a tire pressure monitoring system (TPMS) and 5 sensors (4 wheels + spare). In October, messages about pressure testing in all tires began to appear on the dashboard with the indicator on fire, then these messages disappeared and the indicator went out. Reading errors through SDD did not give a result (no errors). The system is extremely simple 4 antennas and 1 unit (located in the rear right sidewall). Having called the antenna to break the short circuit, I found out that everything is fine with them. The block itself remained in question. After conducting a study (a series of tests to check the performance), it turned out that the unit responds to a decrease in pressure in the wheels but forgets these values. After opening the unit, he discovered that he turned green, cleaned it, put it in its place … the module’s working capacity did not return.

Decided to buy a new module. Winter came to the car set new wheels with new sensors.
and dropping an error module TPMS went home with the confidence that I would have to plug in a computer and prescribe sensor numbers manually, since I did not want to engage in shamanism with a spare wheel. BUT … a miracle happened and the system picked up all the sensors and after 40 minutes the system did not fail. Now on the tidy does not annoy me amber flat tire icon.
