Automatic Transaxle System -- Initialization



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 be performed only with the Techstream.
HINT:
The ECM memorizes the condition that the ECT controls the automatic transaxle assembly and engine assembly according to those characteristics. 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 memorize the new information.
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 and the Techstream main switch on.

  4. Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory. Then, press "Next".

    CAUTION:
    After performing the RESET MEMORY, be sure to perform the ROAD TEST (COROLLA_ZRE142 RM000000W790MNX.html) described earlier.
    HINT:
    The ECM is learned by performing the ROAD TEST.
