Deactivate INVECS-2

This function is used to deactivate the control system "Intelligent & innovative vehicle electronic control system (INVECS-2)".
Note:
This function deactivates the control system INVECS-2 and change shift patterns to standard patterns. If the ignition is turned to OFF - ON - OFF, it will activate INVECS-2.
Below is information about performance of road test in conjunction with deactivated INVECS-2.

Inspection procedure if there is an abnormality
4A/T
Selector lever in position D (Must be done on a level and straight road).
1. Accelerate to 4th range at an accelerator pedal position sensor (APS) output of 1.5 V (opening angle 20%).
Data list no. 8 (speed sensor output shaft), 29 (accelerator pedal position). The shifting points correspond with the diagnostic tool display and the APS voltage (opening angle) and output shaft.
Problem during shifting.

Shocks, engine racing.


2. Slowly decelerate and stop the vehicle.

Incorrect shift points

All points


3. Accelerate to 4th range at an accelerator pedal position sensor (APS) output of 2.5 V (opening angle 50%).
