Thanks to Vadimus who has developed the function of disabling TPMS with Lexia 3 diagnostic system in Mitsubishi forum. The method was first tested on his Mitsubishi Outlander.
Lexia 3 diagnostic system is designed for Peugeot and Citroen vehicles. Why is able to diagnose Mitsubishi vehicles? Because both Peugeot and Citroen had or still have models which are rebranded versions of Mitsubishi Outlander/RVR so they made their tool to support those Mitsubishi clones.
