2009 Toyota Corolla Repair Question
If the R is blinking, there should be a problem there. What scan tool did you use to check codes?
A snap on scanner with the keys even under transmission codes nothing popped up
Under normal circumstances the R indicator light should not be blinking even if a fault had been detected. I believe the Park and Neutral Position switch for the Reverse circuit has a loose connection somewhere or the PCM is the one causing it.
Check the PNP switch wire harness connector for a loose or contaminated connections forst.
All the connections are fine all the gears work except reverse maybe a bad Tranny?
Is possible for the trans to be bad but your vehicle is too new to be having problems. More likely to be control problems.
I would suggest testing the wirings for continuity in circuit and also the PNP switch and PCM.
Where are the pnp and pcm switches located?
And neutral is in gear as well this is weird
When gear shift is in N and gears are engaged, either the gear shift cable is out of adjustment or the transmission has internal faults.
