RESET MEMORY FOR ELECTRONIC CONTROLLED AUTOMATIC TRANSMISSION (FOR A750E, A750F)

NOTICE:

1. Perform the RESET MEMORY procedures (A/T initialization) when replacing the automatic transmission assembly, engine assembly or ECM.
2. The RESET MEMORY can be performed only with the intelligent tester.

HINT:

  The ECM memorizes the vehicle conditions when the ECT controls the automatic transmission assembly and engine assembly. Therefore, when the automatic transmission assembly, engine assembly, or ECM has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.

  The reset procedures are as follows.

1. Turn the ignition switch OFF.

2. Connect the intelligent tester to the DLC3.

3. Turn the ignition switch ON and push the intelligent tester main switch ON.

4. Perform the reset memory procedure from the main menu.

   CAUTION:
     After performing the RESET MEMORY procedures, be sure to perform the Road Test (Click here) as described earlier.

   HINT:
     The ECM learns through the Road Test.

RESET COMPASS IN COMBINATION METER

CAUTION:

1. Strictly observe posted speed limits, traffic laws and road conditions.
2. Make sure no people are near the vehicle.

NOTICE:

1. Perform the circling calibration in a spacious area that does not have artificial magnetic influence. For example, underground parking lots, areas under a steel tower and areas between tall buildings are not acceptable.
2. When performing calibration, do not operate the air conditioner, power windows, or any other electrical equipment.
3. A compass may become magnetized during shipping by vessels or freight cars. Make sure to perform calibration and ensure that the calibration described below, the vehicle's magnetic field may be interfering with the calibration. Demagnetize the vehicle using a demagnetizer and perform the calibration again.

1. Circling calibration

   1. Select compass mode.

   2. Press and hold INFO for 3 seconds to enter the compass correction mode.

   3. Press RESET.

   4. Drive the vehicle slowly in a circle once within 128 seconds.

      HINT:
      1. If the circling calibration is completed, the correct direction is displayed automatically.
      2. If the correct direction is not displayed after driving the vehicle as specified, change the vehicle location.

   5. If there is not enough space to drive in a circle, perform the following:

      1. Drive the vehicle forward with the steering wheel fully turned to the right, and then drive in reverse with the steering wheel fully turned to the left.
      2. Repeat the pattern above 2 times within 128 seconds.

      HINT:
      1. If the circling calibration is completed, the correct direction is displayed automatically.
      2. If the correct direction is not displayed after driving the vehicle as specified, change the vehicle location.

2. Compass correction mode cancelLation

   1. Press RESET after performing the circling calibration.

   2. Press INFO or wait for 6 seconds to end the compass correction mode.

3. Zone setting

   1. Select compass mode.

   2. Press and hold INFO button for 3 seconds to enter compass correction mode.

   3. Press H to select a higher zone number.

   4. Press M to select a lower zone number.

   5. Press INFO or wait for 6 seconds to end compass correction mode.
