Automatic Transmission System: Initialization

RESET MEMORY
CAUTION: Perform the RESET MEMORY (AT initialization) when replacing the automatic transmission assembly, engine assembly or ECM.

NOTE: Intelligent tester only

HINT:

The ECM stores the conditions under which the ECT (Electronic Controlled Automatic Transmission) controls the automatic transmission and engine assemblies according to their characteristics. 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 store the new information. Reset procedure is as follows.
1. Turn the ignition switch off.
2. Connect the intelligent tester together with the CAN VIN (controller area network vehicle interface module) to the DLC3.
3. Turn the ignition switch to the ON position and push the intelligent tester main switch on.
4. Select the items "DIAGNOSIS / ENHANCED OBD II".
5. Perform the reset memory procedure from the ENGINE menu.
  CAUTION: After performing the RESET MEMORY, be sure to perform the ROAD TEST described earlier.
  
  HINT:
  
  The ECM stores the new information during the ROAD TEST.
