Programming and Relearning

U140F AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: INITIALIZATION

1. RESET MEMORY

NOTICE:
* Perform RESET MEMORY (AT initialization) when replacing the automatic transaxle assembly, engine assembly or ECM.
* RESET MEMORY can be performed only with the Techstream.

HINT
The ECM learns various conditions and controls the automatic transaxle assembly and engine assembly according to those characteristics. 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 re-learn.

Reset procedure is as follows.

(a) Turn the ignition switch off.

(b) Connect the Techstream to the DLC3.

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

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

CAUTION:
After performing RESET MEMORY, be sure to perform the ROAD TEST Road Test described earlier.

HINT
The ECM learns when the ROAD TEST is performed.
