Automatic Transmission System: Initialization

RESET MEMORY
NOTE:
- Perform the RESET MEMORY procedures (A/T initialization) when replacing the automatic transmission assembly, engine assembly or ECM.
- 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 CAN VIM. Then connect the CAN VIM to the DLC3.
3. Turn the ignition switch ON and push the tester main switch ON.
4. Enter the following menus: DIAGNOSIS / ENHANCED OBD II.
5. Perform the reset memory procedures from the main menu.
  CAUTION: After performing the RESET MEMORY procedures, be sure to perform the ROAD TEST as described earlier.
  
  HINT:
  
  The ECM learns through the ROAD TEST.
