Initialization
U660E AUTOMATIC TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: INITIALIZATION
INITIALIZATION
1. RESET TRANSAXLE COMPENSATION CODE
NOTICE:
- If the following parts have been replaced, initialize the TCM and perform the following "Reset Memory" and "Perform Road Test to Allow TCM to learn" steps.
- Valve body assembly
- Shift solenoid valve SL3
- Shift solenoid valve SL4
- TCM
- The transaxle compensation code can only be initialize with the Techstream.
HINT: The TCM memorizes the condition that the ECT controls the automatic transaxle assembly according to those characteristics. Therefore, when the automatic transaxle assembly, or TCM has been replaced, it is necessary to reset the memory so that the TCM can memorize the new information. Reset procedure is as follows:
(a) Move the shift lever to N or P.
(b) Turn the engine switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the engine switch on (IG).
(e) Turn the Techstream on.
(f) Enter the following menus: Powertrain / ECT / Utility / A/T Code Reset.
(g) Press "Next" again to proceed.
NOTE:
After the transaxle compensation code is initialized, perform the following "Reset Memory" and "Perform Road Test to Allow TCM to learn" steps.
(h) Press "Exit".
2. PERFORM ROAD TEST TO ALLOW TCM TO LEARN
NOTE:
Perform the following procedures while strictly observing all traffic laws and speed limits.
(a) Warm up the engine.
(b) From a standstill, achieve highest possible speed with the accelerator pedal opened 15% or less. Keep the accelerator pedal angle steady while driving the vehicle.
(c) Repeat the previous step until shift shock no longer occurs.
(d) From a standstill, achieve highest possible speed with the accelerator pedal opened 25% or more. Keep the accelerator pedal angle steady while driving the vehicle.
(e) Repeat the previous step until shift shock no longer occurs.
3. RESET MEMORY
NOTICE:
- The RESET MEMORY can be performed only with Techstream.
HINT: The TCM (ECT) memorizes the vehicle conditions when controlling the automatic transaxle assembly and engine assembly.
Therefore, when the automatic transaxle assembly, valve body assembly, shift solenoid valve SL3, shift solenoid valve SL4, or TCM has been replaced, it is necessary to reset the memory so that the TCM can memorize the new information.
(a) Reset procedure is as follows:
(1) Turn the engine switch off.
(2) Connect Techstream to the DLC3.
(3) Turn the engine switch on (IG).
(4) Turn Techstream main switch on.
(5) Select the following items: "Powertrain / ECT / Utility / Reset Memory". Then, press "Next".
NOTE:
After performing Reset Memory, be sure to perform "Perform Road Test to Allow TCM to Learn" described earlier.
