INITIALIZATION
1. RESET MEMORY
NOTICE:
HINT:
The ECM memorizes the control conditions of the automatic transmission assembly and engine assembly. Therefore, when the automatic transmission assembly, valve body assembly or any of the shift solenoid valves has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.
The reset procedure is as follows.
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory.
NOTICE:
After performing Reset Memory, be sure to perform the Road Test (See page
) described earlier.
HINT:
The ECM learns through the Road Test.
2. ATF THERMAL DEGRADATION ESTIMATE RESET
NOTICE:
If either of the following conditions is met, perform ATF Thermal Degradation Estimate Reset.
HINT:
If 50000 or more is displayed for the Data List item "ATF Thermal Degradation Estimate", thermal degradation of the ATF is suspected. Perform ATF Thermal Degradation Estimate Reset after replacing the ATF.
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
NOTICE:
Do not start the engine.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Utility / ATF Thermal Degradation Estimate Reset.
