I believe the early sensors transmit at 313mhz.
The later ones 433mhz
So although your sensors are working there probably not on the correct frequency for the car to recognise them.
The Tpms light can be turned off using iid tool until you get the correct sensor.
Special programs off related to the fuse in the curling tongue circuit blowing.
Also worth checking the perming solution reservoir located next to the red and white striped pole.
Hope that clears it all up.
Gave the 90 Diffs, transfer box, gearbox and engine an oil change, greased the props then went machine mart and bought a compressor and accessories then started waxoyling, horrible job and to finish tomorrow, ready to get it muddy again.
