transmission checked at the earliest

the pushbutton shift selector.
o Press any range button «D», «N» or «R» on

code).
o Wait until the calibrated time (approximately
10 minutes) has passed. The system will
automatically return to the normal operating
mode.
o Turn off power to the TCM (shut off the
engine using the ignition key).
NOTE
If clearing a code while locked in a «D» (Drive)
or «R» (Reverse) position (fail-to-range), the
transmission will still be in «D» (Drive) or «R»
(Reverse) when the clearing procedure is
completed. «N» (Neutral) must be manually
selected.
