  1. After the vehicle is identified, select the following items from initialization of the M-MDS.
    1. Select "Self-test"
    2. Select "Module"
    3. Select "TCM"
    4. Select "Retrieve CMDTCs"
      NOTE:
      • DTC P06B8:00 is displayed while the initial learning has not been implemented.

    CAUTION:
    • When the brake fluid pressure sensor value is the specification or less, shut down the initial learning to assure safety. Accordingly, be careful of the following when performing the initial learning:
      • Strongly depress the brake pedal while performing the initial learning. (Brake hydraulic pressure is 5 MPa {51 kgf/cm2 , 725 psi} or more.)
      • Do not depress the brake pedal again. Otherwise, the brake booster pressure will decrease and the brake force will weaken.
    1. Shift the selector lever from P position to D position and click the DTC clear button for the M-MDS.

      NOTE:
      • The initial learning implements after idle speed starts increasing. If idle speed does not start increasing, repeat the procedure from Step  2.
      • The shift position indication does not turn off while the initial learning is being implemented.
      • If the initial learning is shut down for any reason while performing the learning, shift position indication does not flash. If shift position indication does not flash, repeat the procedure from Step  2.
    3. Verify that the engine speed returns to idle and shift position indication flashes two times  .

  5. Switch the ignition to KOEO and verify the DTC.
