INITIALIZATION

RESET MEMORY

NOTICE:

Perform the RESET MEMORY (AT initialization) when replacing the automatic transmission
assy or ECM.

The RESET MEMORY can be performed only with the Hand–held tester.

HINT:
The ECM memorizes the condition that the ECT controls the automatic transmission assy and engine assy
according to those characteristics. Therefore, when the automatic transmission assy, engine assy, or ECM
has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.
Reset procedure is as follows.

Turn the ignition switch off.

(b)

Connect the hand–held tester to the DLC3.

(c)

Turn the ignition switch to the ON position.

(d)

Turn the hand–held tester main switch on.
