    3. Release the connector and pull it off from the Transmission Control Module (TCM).
      4.  
    4. If equipped, loosen the side turn signal wiring from the bracket on the Transmission Control Module (TCM).
      5.  
    5. If equipped, remove the left side turn signal from the fender toward the outside, via the bolts.
      NOTE
      The Transmission Control Module (TCM) is still hooked in on the backside.

      6.  
    6. Push the Transmission Control Module (TCM) upward together with the bracket and then remove them.
      7.  
    7. Remove the old Transmission Control Module (TCM) from the bracket via the bolts.
      8.  

    To install:

    1. Set the new Transmission Control Module (TCM) in place and fasten it.
      2.  
    2. Set the connector onto the Transmission Control Module (TCM) and lock it into place.
      3.  
    3. Check whether the new control module identification matches the old control module identification.
      4.  
    4. When the harness connector is disconnected from the Transmission Control Module (TCM) or the battery is disconnected, all of the adaptation values in Transmission Control Module (TCM) are erased. However, the DTC memory content will remain intact. If the engine is started after this, the idle may be rough for a short period. In this case, the readiness code must be generated again.
