2021 Mazda CX-3 AWDFACTORY OEM SERVICE PROCEDURE

D Position Test: Notes

  1. Perform road test preparations. (See ROAD TEST PREPARATION .)
  2. Warm up the transaxle.
  3. Select D position.
  4. Inspect the shift point for the D position in normal mode.
    • If there is any malfunction, refer to symptom troubleshooting and verify the malfunction symptom.
    1. Depress the accelerator pedal and start the vehicle, and verify that the gears shift from 1st to 2nd, 2nd to 3rd, 3rd to 4th, 4th to 5th, and 5th to 6th. In addition, verify that the vehicle speed corresponds to the shift point when shifting.
    2. Release the accelerator pedal while driving in 6th gear, and verify that the gears shift from 6th to 5th, 5th to 4th, 4th to 3rd, 3rd to 2nd, and 2nd to 1st. In addition, verify that the vehicle speed corresponds to the shift point when shifting.
      NOTE:
      • When the accelerator pedal is fully released quickly, shifting is not performed according to the shift pattern because the gear being used may be maintained.
      • When decelerating by strongly depressing the brake pedal, shifting is not performed according to the shift pattern because the shift-down point may be at high vehicle speed.
    3. Kickdown while driving in 6th, 5th, 4th, 3rd, and 2nd gears, and verify that the gears shift from 6th to 5th, 5th to 4th, 4th to 3rd, 3rd to 2nd, and 2nd to 1st. In addition, verify that the vehicle speed limit for kickdown corresponds to the shift point.
    4. Verify that the shift shock is minimal, shifting is smooth and timely, and there is no abnormal noise or slip.
    5. Verify that the TCC is engaged.
