INITIAL LEARNING [FW6A-EL]


id0517h1119100

Warning
•  When performing the initial learning, apply the parking brake securely and block the front and rear wheels using wheel blocks so that the vehicle does not move. Otherwise, the vehicle may move which could lead to an accident because the gears are forcibly changed with the engine running and the shift lever in the drive position while in the initial learning.

Introduction

•  If the initial learning is not completed, perform the initial learning if any of the following parts is replaced. Otherwise, engine racing may occur or shift shock may increase.
―  Control valve body
―  Oil pressure switch
―  Clutch (low clutch, high clutch, R-3-5 brake, 2-6 brake, and low and reverse brake)
―  Automatic Transaxle
•  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 advanced keyless entry and push button start system and those without it. The initial learning can be activated easily using the M-MDS regardless of whether or not the advanced keyless entry and push button start system is equipped.

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. (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION [FW6A-EL].)

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 M-MDS.

(1)  Select “Data logger”.
(2)  Select “Module”.
(3)  Select “TCM”.

8.  While checking the PID TFT (ATF temperature), warm-up the engine and allow the ATF temperature to reach 60—110 °C {140—230 °F}.


Initial learning procedure

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”

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

Caution
•  When performing the initial learning, initial learning ends for safety purposes when the brake fluid pressure sensor value is the specification or less. When performing the initial learning, be careful of the following.
―  Forcefully depress the brake pedal while initial learning is being implemented. (Brake hydraulic pressure 5 MPa {51 kgf/cm2, 725 psi} or more)
―  Do not depress the brake pedal after releasing it. Otherwise, the power brake fluid pressure will decrease and weaken the braking force.

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

(1)  Shift the selector lever from P position to D position and click the DTC clear button for the M-MDS.
(2)  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.".
(3)  Verify that the engine speed returns to idle and the AT warning light flashes two times.

(4)  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.  Clear DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FW6A-EL].)

6.  Switch the ignition off.

7.  Switch the ignition ON (engine off or on).

8.  Using the M-MDS, verify that DTC P06B8:00 has not been stored. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FW6A-EL].)

•  If DTC P06B8:00 is displayed, switch the ignition off and repeat the procedure from Step 2.
•  If any other DTCs are displayed, repair the malfunctioning location according to the applicable DTC troubleshooting. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [FW6A-EL].)
