A750F AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMISSION SYSTEM: INITIALIZATION

INITIALIZATION

1. RESET MEMORY
NOTICE:
- Perform the Reset Memory (AT initialization) when replacing the automatic transmission assembly, engine assembly or ECM.
- The Reset Memory can be performed only with Techstream.
HINT: The ECM memorizes the vehicle conditions when the ECT controls the automatic transmission assembly and engine assembly. Therefore, when the automatic transmission assembly, engine assembly, or ECM 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) Turn the ignition switch OFF.
(b) Connect Techstream to the DLC3.
(c) Turn the ignition switch ON, and turn the tester main switch ON.
(d) Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory.
CAUTION:
After performing the Reset Memory, be sure to perform the ROAD TEST Road Test described earlier.
HINT: The ECM learns through the ROAD TEST.
