Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.
Judgement of A/T InterlockNCS001EH
When A/T Interlock is judged to be malfunctioning, the vehicle should be fixed in 2nd gear, and should be set
in a condition in which it can travel.
When one of the following fastening patterns is detected, the fail-safe function in correspondence with the indi-
vidual pattern should be performed.
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.
