U241E AUTOMATIC TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: INITIALIZATION

INITIALIZATION

1. RESET MEMORY
NOTICE:
- Perform the RESET MEMORY (AT initialization) when replacing the automatic transaxle assembly, engine assembly or ECM.
- The RESET MEMORY can be performed only with an intelligent tester or Techstream.
HINT: The ECM stores the control conditions of 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 store the new information.
The reset procedure is as follows.

(a) Connect an intelligent tester or Techstream to the DLC3.
(b) Turn the ignition switch to ON and turn the tester switch ON.
(c) Enter the following menus:
(1) Intelligent tester - Select: DIAGNOSIS / ENHANCED OBD II / RESET MEMORY.
(2) Techstream - Select: Powertrain / Engine and ECT / Utility / Reset Memory.
NOTE: After performing the RESET MEMORY, be sure to perform the ROAD TEST Road Test described earlier.
HINT: The ECM learns through the ROAD TEST.
