RESET MEMORY
NOTICE:
  1. Perform the RESET MEMORY (AT initialization) when replacing the automatic transmission assembly, engine assembly or ECM.
  2. The RESET MEMORY can be performed only with the Intelligent tester.
HINT:
The ECM memorizes the condition that the ECT controls the automatic transmission assembly and engine assembly according to those 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 memorize the new information.
Reset procedure is as follows.

  1. Turn the engine switch off.

  2. Connect the intelligent tester to the DLC3.

  3. Turn the engine switch on (IG) position.

  4. Turn the intelligent tester main switch on.



  5. Perform the reset memory procedure from the main menu.

    CAUTION:
    After performing the RESET MEMORY, be sure to perform the ROAD TEST (Click here) described earlier.
    HINT:
    The ECM is learned by performing the ROAD TEST.
