INITIALIZATION
1. RESET MEMORY

NOTICE:
^ Perform the RESET MEMORY (AT initialization) when replacing the automatic transmission assembly, engine assembly or ECM.
^ The RESET MEMORY can be performed only with the intelligent tester or Techstream.

HINT: The ECM memorizes the control conditions of 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. Reset procedure is as follows.

(a) Connect the intelligent tester or Techstream to the DLC3.
(b) Turn the ignition switch ON and push the tester switch ON.
(c) Enter the following menus:
(1) Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / ECT / RESET MEMORY /
(2) Techstream - Select: Powertrain / Engine and ECT / Utility / Reset Memory /

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

HINT: The ECM learns through the ROAD TEST.
