REPAIR INSTRUCTION INITIALIZATION

Note

When disconnecting the cable from the negative (-) battery terminal, initialize the following system(s) after the cable is reconnected.



  1. INITIALIZATION RELATED TO A750F AUTOMATIC TRANSMISSION SYSTEM


    1. RESET MEMORY

      Note


      • Perform the RESET MEMORY procedures (A/T initialization) when replacing the automatic transmission assembly, engine assembly or ECM.

      • The RESET MEMORY can be performed only with the intelligent tester.

      Tech Tips

      The ECM memorizes the vehicle conditions when the ECT controls the automatic transmission assembly and engine assembly. 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.

      The reset procedures are as follows.


      1. Turn the ignition switch OFF.

      2. Connect the intelligent tester to the DLC3.

      3. Turn the ignition switch ON and push the intelligent tester main switch ON.

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

        CAUTION:

        After performing the RESET MEMORY procedures, be sure to perform the Road Test Click here as described earlier.

        Tech Tips

  3. REGISTRATION RELATED TO WIRELESS DOOR LOCK CONTROL SYSTEM (for Built-in Type Door Control Receiver)


    1. DESCRIPTION OF CODE REGISTRATION

      Tech Tips


      • Recognition code registration is necessary when replacing the door control transmitter or the door control receiver.

      • Add mode is used to register new recognition codes while retaining codes already registered. This mode is used when a new transmitter is added. If the number of registered codes exceeds 4, the previously registered codes will be erased in order, starting from the first registered code.

      • Rewrite mode is used to erase all previously registered recognition codes in order to register new recognition codes. This mode is used when the transmitter or the receiver is replaced.

      • Synchronization mode is used to renew the sequential code (rolling code) of the transmitter and synchronize it with the registered recognition code. This mode is used when the transmitter does not function because they are unsynchronized. Up to 4 transmitters can be synchronized at once (If a transmitter's switch is pressed while out of range of the theft warning ECU, the system will not be able to synchronize the sequential code (rolling code) with the registered recognition code. At this time, the system will automatically synchronize them. However, automatic synchronization can be performed only 500 times. Therefore, it its necessary to use this mode after they have synchronized 500 times).

      • Erase mode is used to erase all the registered codes and disable the wireless door lock function. This mode is used when the transmitter is lost.

      • All of the following registration procedures must be performed in order.

    2. REGISTER RECOGNITION CODE
