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.

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.
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory.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.
