A/T Interlock Nissan 350Z I facelift

Automatic Transmission

A/T Interlock

If there is an A/T interlock judgment malfunction, the transmission is fixed in 2nd gear to make driving possible. NOTE: When the vehicle is driven fixed in 2nd gear a turbine revolution sensor malfunction is displayed, but this is not a turbine revolution sensor malfunction.
When interlock is detected at the 3rd gear or more, it is locked at the 2nd gear.
