U140F AUTOMATIC TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: INITIALIZATION

1. RESET MEMORY

NOTICE:
* Perform the RESET MEMORY procedures (A/T initialization) when replacing the automatic transaxle assembly, engine assembly or ECM.
* RESET MEMORY can be performed only with Techstream.
HINT
The ECM memorizes the vehicle conditions when the ECT controls the automatic transaxle assembly and engine assembly. Therefore, when the automatic transaxle 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.

(a) Turn the ignition switch off.

(b) Connect Techstream to the DLC3.

(c) Turn the ignition switch to ON and turn the Techstream on.

(d) Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory. Then, press "NEXT".

(e) Perform the reset memory procedures from the main menu.

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.
