Initialization [09/2014 - ]

  1. PERFORM ROAD TEST TO ALLOW TCM TO LEARN 
    WARNING:
    • Perform the following procedures while strictly observing all traffic laws and speed limits.
    • Do not accelerate or decelerate rapidly.
    1. The "road test" procedure is as follows:
      1. Warm up the engine.
      2. According to the replaced parts, perform the appropriate road test shown below.
        Replaced Parts Road Test
        • Automatic transmission assembly
        • TCM
        • Valve body assembly
        • Shift solenoid valve SL3
        • Engine assembly
        Perform pattern 1, 2 and 3
        Pattern 1:*1
        1. With the shift lever in D, after gradually accelerating to 50 km/h (31 mph) or more, gradually decelerate to approx. 30 km/h (19 mph)

        Pattern 2:
        1. When driving at approximately 50 km/h (31 mph) with the D4 range selected, release the accelerator pedal to allow the vehicle to decelerate gradually to approximately 10 km/h (6 mph).

        Pattern 3:*2
        1. Accelerate to a speed higher than 50 km/h (31 mph). While gradually decelerating with the shift lever in M and 5th gear selected, downshift to 4th gear at approx. 50 km/h (31 mph), to 3rd gear at approx. 40 km/h (25 mph), and to 2nd gear at approx. 30 km/h (19 mph).
        • Shift solenoid valve SL1
        • Shift solenoid valve SL2
        • Shift solenoid valve SL4
        • Shift solenoid valve SL5
        Perform pattern 1 and 3
        Pattern 1:*1
        1. With the shift lever in D, after gradually accelerating to 50 km/h (31 mph) or more, gradually decelerate to approx. 30 km/h (19 mph)

        Pattern 3:*2
        1. Accelerate to a speed higher than 50 km/h (31 mph). While gradually decelerating with the shift lever in M and 5th gear selected, downshift to 4th gear at approx. 50 km/h (31 mph), to 3rd gear at approx. 40 km/h (25 mph), and to 2nd gear at approx. 30 km/h (19 mph).

        HINT: 

        • *1: After gradually accelerating for a distance of approximately 130 m (426.4 ft.) for a period of approximately 15 seconds, gradually decelerate for a distance of approximately 45 m (147.6 ft.) for a period of approximately 5 seconds.
        • *2: Accelerate the vehicle to a speed slightly higher than 50 km/h (31 mph).

          Move the shift lever to M and select 5th gear.

          Release the accelerator pedal and allow the vehicle to decelerate gradually.

          When the vehicle decelerates to approximately 50 km/h (31 mph), downshift to 4th gear.

          When the vehicle decelerates to approximately 40 km/h (25 mph), downshift to 3rd gear.

          When the vehicle decelerates to approximately 30 km/h (19 mph), downshift to 2nd gear.

        • When decelerating, apply the brakes as necessary to adjust the vehicle speed.

        NOTE:
        • *1: The speed, time and distance values are approximate values.
        • *2: After accelerating, the deceleration does not need to be performed immediately.
        • *3: There is no specified time or distance.
      3. Repeat the road tests until the shift shock and engine speed overrun (engine speed flare when shifting) reach an acceptable level.
        NOTE:

        When repeating the acceleration/deceleration cycle of a road test pattern, bring the vehicle to a complete stop before accelerating again.

  2. RESET MEMORY 
    NOTE:
    • Perform Reset Memory (AT initialization) when replacing the engine assembly or ECM.
    • Reset Memory can be performed only with the Techstream.
    • Reset Memory cannot be completed by only disconnecting and reconnecting the cable to the negative (-) battery terminal.

    HINT: 

    The TCM (ECT) memorizes the vehicle conditions when controlling the automatic transmission assembly and engine assembly.

    1. The "Reset Memory" procedure is as follows:
      1. Turn the engine switch off.
      2. Connect the Techstream to the DLC3.
      3. Turn the engine switch on (IG).
      4. Turn the Techstream on.
      5. Enter the following menus: Powertrain / ECT / Utility / Reset Memory.

        Powertrain > ECT > Utility

        NOTE:

        After performing Reset Memory, be sure to perform "Perform Road Test to Allow TCM to Learn" described earlier.
