How to Reprogram Tire Low Pressure Warning
How to reprogram the set threshold used by JGC to warn us that a tire pressure is too low? Can only a dealer do it?
I swap my 20” wheels for 18” on an Overland with equivalent tire circumference. Original (20”) tires require 36 psi while new (18”) tires require only 33 psi.
I get low pressure at 30 psi and message request to inflate to original pressure (36 psi). I want to change the message to inflate to 33 psi and lower the set threshold for warning.
How to do it?
