shift pattern

Stops the INVECS-II 
control and shifts 
gears according to 
the standard shift 
pattern.

Use this function when performing procedure 8 in 
the road tests (Refer to 

P.23A-18

).

The INVECS-II cancel command will last until the 
ignition switch is turned from "ON" to "LOCK" 
(OFF) or vice versa.
