bolts of electric throttle control actuator (bank 2) is the same as
that of the electric throttle control actuator (bank 1).

• Perform the “Throttle Valve Closed Position Learning” when har-

ness connector of electric throttle control actuator is discon-
nected. (This work is recommended to be performed by GT-R
certified NISSAN dealer.)

• Perform the “Idle Air Volume Learning” and “Throttle Valve

Closed Position Learning” when electric throttle control actuator is replaced. (This work is recommended to
