Initialization
INITIALIZATION1. 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) "Road test" procedure is as follows:
(1) Warm up the engine.
(2) According to the replacement parts, perform the road test shown below.
HINT:
^ *1: After gradually accelerating a distance of approximately 130 m (426.4 ft.) for a period of approximately 15 seconds, gradually decelerate a distance of approximately 45 m (147.6 ft.) for a period of approximately 5 seconds.
^ *2: After gradually accelerating a distance of approximately 40 m (131.2 ft.) for a period of approximately 8 seconds, gradually decelerate 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 speed overrun settles down.
NOTICE: Before repeating tests, stop the vehicle once, and then start moving the vehicle again.
2. RESET MEMORY
NOTICE:
^ Perform the RESET MEMORY (AT initialization) when replacing the engine assembly or ECM.
^ The RESET MEMORY can be performed only with the intelligent tester or 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 transmission assembly and engine assembly.
(a) "RESET MEMORY" procedure is as follows:
(1) Turn the engine switch off.
(2) Connect the intelligent tester or Techstream to the DLC3.
(3) Turn the engine switch on (IG).
(4) Turn the tester ON.
(5) Enter the following menus:
Intelligent tester
Select: DIAGNOSIS / OBD/ MOBD / ECT / RESET MEMORY.
Techstream
Select: Powertrain / ECT / Utility / Reset Memory.
NOTICE: After performing the RESET MEMORY, be sure to perform the ROAD TEST described previously. Road Test
