Initialization

AA80F AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMISSION SYSTEM: INITIALIZATION

INITIALIZATION

1. PERFORM ROAD TEST TO ALLOW TCM TO LEARN
CAUTION:
- Perform the following procedures while strictly observing all traffic laws and speed limits.
- Do not accelerate or decelerate rapidly.

(a) The "Road test" procedure is as follows:
(1) Warm up the engine.
(2) According to the parts replaced, perform the road test shown below.





HINT:
- *1: After gradually accelerating over a distance of approximately 130 m (426.4 ft.) for a period of approximately 15 seconds, gradually decelerate over a distance of approximately 45 m (147.6 ft.) for a period of approximately 5 seconds.
- *2: After gradually accelerating over a distance of approximately 40 m (131.2 ft.) for a period of approximately 8 seconds, gradually decelerate over a distance of approximately 20 m (65.6 ft.) for a period of approximately 5 seconds.
- When decelerating, apply the brakes as necessary to adjust the vehicle speed.




HINT:
- *1: The speed, time and distance values are approximate values.
- *2: After accelerating, the deceleration does not need to be performed immediately.
(3) Repeat until the shift shock and engine overrun settles down.
NOTE:
Before repeating tests, stop the vehicle once, and then start moving the vehicle again.

2. RESET MEMORY
NOTICE:
- 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 reconnecting the cable to the negative (-) battery terminal.
HINT: The TCM memorizes the vehicle conditions when the ECT controls the automatic W/transfer transmission assembly and engine assembly.

(a) 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.
NOTE:
After performing Reset Memory, be sure to perform Road Test Road Test described previously.
