Very long story short......
We were able to determine which corner was not recording, which is the passenger front and I know the new sensor was working properly because we switched it to the right rear and it recorded properly until he dug a little deeper and we had these additional problems
These are the basic chain of events .....
Replaced a sensor that coded low battery
Codes cleared, dummy lite went off but info screen never recorded pressure.
After 20 plus miles the dummy lite came back on.
my mechanic put his scanner back on the system used another tool to activate/reset all four wheels sensors, no change.
Next he went a little deeper into the settings with the scanner tool and somehow all four tires on the info screen stopped recording pressures and now the dummy light is on solid with no blinking when you restart the car.
Any suggestions or help would be greatly appreciated
Have a nice day
