RESET MEMORY
NOTICE:
  1. Perform the Reset Memory (AT initialization) when replacing the automatic transaxle assembly, engine assembly or ECM.
  2. The Reset Memory can only be performed using a Techstream.
HINT:
The ECM stores the conditions that the ECT controls the automatic transaxle assembly and engine assembly in accordance with those characteristics. Therefore, when the automatic transaxle assembly, engine assembly, or ECM is replaced, it is necessary to reset the memory so that the ECM can store the new information.
The reset procedure is as follows.

  1. Turn the ignition switch off.

  2. Connect the Techstream to the DLC3.

  3. Turn the ignition switch to ON.

  4. Turn the Techstream on.

    NOTICE:
    After performing the Reset Memory, be sure to perform the Road Test (YARIS_NCP93 RM000000GLE01RX.html) as described earlier.

    The ECM stores learned values by performing the Road Test.
