Had tires rotated and rebalanced and now keep getting no reading from left front. I work at a powersports dealer and have access to a scanner and all monitors are working and batterys show good. Relearn and all is good for about 12 - 15 miles then light comes back on. Did notice that the last time I did the relearn the left front showed 36psi on scanner but 44 psi on dash. Don't want to replace if not needed.
