NOTICE:
* Perform the Reset Memory (AT initialization) when replacing the automatic transmission assembly, valve body assembly or any of the shift solenoid valves.
* Reset Memory can be performed only with the Techstream.
HINT
The ECM memorizes the control conditions of the automatic transmission assembly and engine assembly. Therefore, when the automatic transmission assembly, valve body assembly or any of the shift solenoid valves 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.

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / ECT / Utility / Reset Memory.

CAUTION:
After performing the Reset Memory procedures, be sure to perform the ROAD TEST Road Test as described earlier.

HINT
The ECM learns through the ROAD TEST.
