LEARNING PROCEDURE FOR NEUTRAL POSITION <Vehicles with AS&G system>



PURPOSE


If the following services are carried out, the engine-ECU cannot correctly identify the neutral position. The neutral learning, therefore, must be carried out. If the learning of the neutral position is not completed, the AS&G system is not operated.

  • At installing, removing or replacing neutral position sensor
  • At installing, removing or replacing shift cover Cpl.
  • At replacing engine-ECU
  • At replacing transmission assembly

LEARNING PROCEDURE


note Before learning the neutral position, confirm that the battery voltage and the neutral position sensor are normal. If not normal, carry out the service after solving the problem.

1.After the ignition switch is in "LOCK" (OFF) position, connect the M.U.T.-III to the diagnosis connector.
2.Turn the ignition switch to the ON position and wait for more than 2 seconds. (but do not start the engine.)

3.Place the shift lever in the 3rd position and then place in the 4th position. After that, put it back into the neutral position. Next, place the shift lever to the left (the 1st and 2nd positions) twice to be brought back into the neutral position.
4.Release the shift lever and leave the shift lever in the neutral position for more than 2 seconds.
note During that time, do not start the engine. Pay attention to the vehicle not to produce the vibration to it.
5.Select "MPI/GDI/DIESEL" from System select Screen of the M.U.T.-III.
6.Select "Special Function" from MPI/GDI/DIESEL Screen.
7.Select "Learning" from Special Function Screen.
8.Select "Neutral position learning" from Learning Screen
9.Depress the OK button to learn the neutral position.
10.Turn the ignition switch to the LOCK (OFF) position and wait for more than 15 seconds.
11.Again, turn the ignition switch to the ON position to confirm the following service data of the M.U.T.-III. If the message is different, carry out the learning of the neutral position again.
