2015 Nissan Versa 1.6L with a RE0F11A CVT, Came in with a check engine light, Had a P0705 set in the TCM....Range Switch Circuit A Fault.
Basically, The TCM detected the range switch had output 2 positions at once.
Scan data showed a perfectly working Range Switch.....Back-up lamps work, Brake Input also fine. Along with the LCD indicator on the dash.
Cleared the TCM codes Key On-Engine Off, Code returned immediately upon restart.
This isn't a knock against Nissan.....But I've personally had issues with about EVERY one I work on, Whether it be lack of good/accurate repair information or my scan tools not liking them.
I use a Snap-on Solus Ultra for vehicles I don't have OEM software for.....Which is GM & Ford only at this time.
Of course.....P0705 diagnostic information will have me ohming wires & sampling/monitoring voltages for the rest of my life. Not something I'm going to do with a system that appears to be working as designed.
Idenifix/Direct Hit mentioned (several times) that corroded connections, Broken wires, Or burnt out back-up lamps can cause this code.....The TCM looks for a ground return through the incandescent bulbs in ALL ranges besides reverse! Makes sense & not really a terrible way to sanity check a circuit! But the BU lamps work perfectly, Are bright, And nobody installed LED's that would mess with the ground return back to the TCM!
GM is about the only make I work on that allows a Key On-Engine Running clearing of powertrain codes & the Solus specifically said too clear the TCM codes Key On-Engine Off on this Nissan which I didn't give a second thought to considering past experiences.
I tried clearing the TCM codes Key On-Engine Running....Code cleared!!!!!, And passed inspection, Charged the customer for a Diagnostic (1 hour) & the State Inspection. Advised him that the RE0F11A is on it's last leg as it's shuddering on take off! Yes....I topped off the CVT fluid & it didn't help!
