Mazda 3 Service Manual: Initial Learning [Fw6 A EL]

Introduction

• If the control valve body and oil pressure switch are replaced, always perform the initial learning. If the initial learning is not completed, engine rev-up may occur or shift shock may increase. DTC P06B8:00 is displayed while the initial learning has not been implemented.

• The procedure for the initial learning has a procedure which uses the M-MDS and one which does not. Procedures not using the M-MDS are set for vehicles equipped with the push button start and those without it. The initial learning can be activated easily using the M-MDS regardless of whether or not the push button start is equipped.

WARNING:

• The initial learning forcibly changes gears within the driving shift range while the engine is running. Before implementing the initial learning, securely apply the parking brake and set the wheel blocks for both the front and rear wheels. Otherwise, the vehicle will move which could cause injury or property damage.

Using M-MDS

Preparation before servicing

1. Verify initial learning implementation necessity for replacement parts.

2. Apply the parking brake firmly, and set the wheel blocks for both the front and rear wheels.

3. Inspect the ATF level..

4. Bring the M-MDS inside the vehicle and connect it to the DLC-2.

5. Perform vehicle identification using the M-MDS.

6. Start the engine.

7. After the vehicle is identified, select the following items from initialization of the IDS.

a. Select “Data logger”

b. Select “Module”

c. Select “TCM”

8. While checking the PID, warm-up the engine and allow the ATF temperature to reach 40—110 °C {72—198 °F}

. PID name: TFT (ATF temperature)

Starting procedure for initial learning

1. After the vehicle is identified, select the following items from initialization of the IDS.

a. Select “Self-test”

b. Select “Module”

c. Select “TCM”

d. Select “Retrieve CMDTCs”

NOTE:

• DTC P06B8:00 is displayed while the initial learning has not been implemented.

2. Start the engine and wait for 30 s or more

.

3. Perform the following steps (1) to (4) with the brake pedal depressed.

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.

• Do not depress the brake pedal again. Otherwise, the brake booster pressure will decrease and the brake force will weaken.

a. Shift the selector lever from P position to D position and click the DTC clear button for the M-MDS.

b. When the M-MDS screen returns to the DTC display screen, shift the selector lever from D position to M position within 10 s

and verify that the engine speed increases from idling.

NOTE:

• The initial learning implements after idle speed starts increasing. If idle speed does not start increasing, repeat the procedure from Step 2 "Start the engine and wait for 30 s or more

  .".

• If the initial learning is shut down for any reason while performing the learning, the AT warning light does not flash. If the AT warning light does not flash, repeat the procedure from Step 2 "Start the engine and wait for 30 s or more

  .".

c. Verify that the engine speed returns to idle and the AT warning light flashes two times

.

d. After the AT warning light flashes twice, shift the selector lever from M position to P position and stop the engine.

NOTE:

• Be careful not to miss looking at the AT warning light because the light flashes only one time

  .

4. Release the brake pedal.

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

• If DTC P06B8:00 is displayed, repeat the procedure from Step 2 "Start the engine and wait for 30 s or more

  .". If any other DTCs are displayed, perform the applicable DTC troubleshooting.

Not Using of M-MDS (with push button start)

Preparation before servicing

1. Verify initial learning implementation necessity for replacement parts.

2. Apply the parking brake firmly, and set the wheel blocks for both the front and rear wheels.

3. Inspect the ATF level..

4. Start the engine.

5. Warm-up the engine and allow the ATF temperature to reach 40—110 °C {72—198 °F}

.

Starting procedure for initial learning

1. Start the engine and wait for 30 s or more

.

2. Perform the following steps (1) to (7) with the brake pedal depressed.

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.

• Do not depress the brake pedal again. Otherwise, the brake booster pressure will decrease and the brake force will weaken.

a. Shift the selector lever from P position to N position, press the push button start one time

, and stop the engine.

b. Shift the selector lever from N position to M- position, press the push button start one time

while holding the lever in the M- position, and wait for 5 s or more

(ignition switch ON).

c. Shift the selector lever from M- position to N position, press the push button start one time

, and start the engine.

d. Shift the selector lever from N position to M+ position and wait for 5 s or more

while holding the lever in the M+ position.

e. Select the selector lever from M+ position to M- position and wait for 5 s or more

while holding the lever in the M- position.

f. When starting idle up, shift the selector lever from the M- position to M position and verify that the AT warning light flashes two times

.

NOTE:

• The initial learning implements after idle speed starts increasing. If idle speed does not start increasing, repeat the procedure from Step 1 "Start the engine and wait for 30 s or more

  .".

g. After the AT warning light flashes twice, shift the selector lever from M position to P position and stop the engine.

NOTE:

• Be careful not to miss looking at the AT warning light because the light flashes only one time

  .

3. Release the brake pedal.

4. Clear the DTC using the M-MDS and switch the ignition off.

5. Switch the ignition ON and verify that DTC P06B8:00 is not recorded using the M-MDS.

• If the DTC P06B8:00 is displayed, repeat the procedure from Step 1 "Start the engine and wait for 30 s or more

  .".
