Swapped wheels back to stock today (w/TPMS) and performed VO coding back to TPMS. Reset tire pressure and got all 4 green tires within seconds of moving vehicle. Coded back to FTM and tested a reset. Got all 4 green within seconds. Things looking good!
Not so fast. Now for the final test. Re-mounted the wheels without TPMS and performed a FTM reset. Not going green and I'm expecting TPMS Malfunction in no time. Not sure if there is any other coding that should be done, but my theory is the TPMS hardware actively communicates with the ECUs even when the car is coded FTM (RPA). Without the sensors, I can't get the reset to work even for Flat Tire Monitoring (ABS rolling test for pressure).
